The Company has not independently verified any of the data from third-party sources nor has it verified the underlying economic assumptions relied upon by those third parties.

**PROSPECTUS SUMMARY**

*The SEC allows us to "incorporate by reference" certain information that we file with the SEC, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be part of this prospectus, and information that we file later with the SEC will update automatically, supplement, and/or supersede the information disclosed in this prospectus. Any statement contained in a document incorporated or deemed to be incorporated by reference in this prospectus shall be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained in this prospectus or in any other document that also is or is deemed to be incorporated by reference in this prospectus modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this prospectus. You should read the entire prospectus carefully, including the matters set forth under "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," our financial statements, and related notes included elsewhere in this prospectus and the information incorporated into this prospectus by reference*. *In this prospectus, unless context requires otherwise, references to "we," "us," "our," "INVO Fertility," "INVO," or "the Company" refer to INVO Fertility, Inc. and its subsidiaries.*

**The Company**

We are a healthcare services and technology company focused on the fertility marketplace and dedicated to expanding access to assisted reproductive technology ("ART") care for patients in need. Our principal commercial strategy is focused on building, acquiring, and operating fertility clinics, including "INVO Centers" dedicated primarily to offering the intravaginal culture ("IVC") procedure enabled by our INVOcell® medical device ("INVOcell") and US-based, in vitro fertilization ("IVF") clinics. We have two operational INVO Centers and one IVF clinic in the United States. We also continue to engage in the sale and distribution of our INVOcell technology solution into third-party owned and operated fertility clinics and intend to seek out additional, innovative fertility-focused technologies to license or acquire in order to utilize within our clinics.

In October 2024, we acquired a 100% interest in NAYA Therapeutics, Inc. ("NAYA Therapeutics" or "NTI"), a clinical-stage oncology and autoimmune technology company. In May 2025, we divested an 80.1% ownership interest in NTI, returning to an exclusive focus on the fertility marketplace, and changed our name and ticker symbol to "INVO Fertility, Inc." and "IVF", respectively.

*Fertility Clinics*

On August 10, 2023, we consummated the first acquisition of an existing IVF clinic, the Wisconsin Fertility Institute ("WFI"). As an established and profitable clinic, the consummation of the WFI acquisition more than tripled our annual revenue and became a major part of our clinic-based operations. The acquisition accelerated our expansion from a medical device company to a healthcare services company and immediately added scale and a significant source of positive cash flow to our operations. The acquisition of profitable IVF clinics complements our efforts to build new INVO Centers, and we expect to continue this strategy to accelerate overall growth.

On March 10 and June 28, 2021, we established joint ventures to open INVO Centers in Birmingham, Alabama, and Atlanta, Georgia, respectively. We established these clinics to increase use of the INVOcell, to accelerate the growth and awareness of the IVC procedure and to expand the availability of statistical data supporting its use. These clinics also enabled us to expand our revenue per fertility cycle from hundreds of dollars (from the sale of each INVOcell device) to thousands of dollars, and to significantly advance our path to profitability. We believe dedicated INVO Centers require less investment than traditional IVF clinics and are operationally efficient, making them ideal for underserved secondary markets. We plan on opening additional wholly owned INVO Centers in the coming years.

*INVOcell Device*

Our proprietary technology, INVOcell®, is an innovative medical device that allows fertilization and early embryo development to take place in vivo within the woman's body. This treatment solution is the world's first intravaginal culture technique for the incubation of oocytes and sperm during fertilization and early embryo development and provides patients with a connected, intimate, and affordable experience. As reflected in available data, we believe the IVC procedure can deliver comparable results at a lower cost than traditional IVF and is a significantly more effective treatment than intrauterine insemination ("IUI").

Unlike IVF, where the oocytes and sperm develop into embryos in an expensive laboratory incubator, the INVOcell allows fertilization and early embryo development to take place in the woman's body. The IVC procedure can provide many benefits, including the following:

● May reduce lab procedures, helping clinics and doctors to increase patient capacity, lower costs and offer a more affordable advanced fertility treatment option;

● Provide a more natural, stable incubation environment;

● Offer a more personal, intimate experience in creating a baby; and

● Reduce the risk of errors in the lab.

In both current utilization of the INVOcell, and in clinical studies, the IVC procedure has demonstrated equivalent pregnancy success and live birth rates as IVF.

While INVOcell remains part of our efforts, our commercial and corporate development strategy within the fertility market has expanded to focus more broadly on providing ART services through our emphasis on operating clinics. However, we will continue to provide INVOcell as well as seek out additional, innovative technologies, we can utilize to benefit patients and enhance our clinic operations.

**Certain Recent Developments**

 

*Warrant Inducement*

 

<u>Inducement Letter Agreement</u>

On January 28, 2026, we entered into the Inducement Letter Agreement with Armistice, which was a holder of certain warrants (the "Existing Warrants") to purchase up to 4,733,728 shares of the Common Stock. The Existing Warrants were originally issued on December 3, 2025, with an exercise price of $1.69 per share.

The issuance of the shares of Common Stock upon exercise of the Existing Warrants is registered pursuant to a registration statement on Form S-1 (File No. 333-292206), which was declared effective by the Securities and Exchange Commission on December 29, 2025.

Pursuant to the Inducement Letter Agreement, Armistice agreed to exercise the Existing Warrants for cash at a reduced exercise price of $1.59 per share in consideration for the Company's agreement to issue the Inducement Warrant

We agreed to file a registration statement on Form S-1 (or other appropriate form if it is not eligible to utilize Form S-3) providing for the resale of the shares (the "Inducement Warrant Shares") of Common Stock issuable upon the exercise of the Inducement Warrant (the "Resale Registration Statement") on or before the 15th calendar day following the date of the closing of the exercise of the Existing Warrants (the "Closing Date"), and to use commercially reasonable best efforts to cause the Resale Registration Statement to become effective within sixty (60) calendar days following the Closing Date (or within ninety (90) calendar days following the Closing Date in case of "full review" of such registration statement by the Commission) (the "Effectiveness Date").

Pursuant to the Inducement Letter Agreement, except for certain exempt issuances set forth in the Inducement Letter Agreement, we agreed not to issue, enter into any agreement to issue or announce the issuance or proposed issuance of any Common Stock or Common Stock equivalents or file any registration statement or any amendment or supplement to any existing registration statement, subject to certain exceptions, for a period of 30 trading days after date of the Inducement Letter Agreement. In addition, from the date of the Inducement Letter Agreement until three (3) months following the Effectiveness Date, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any subsidiary of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction. "Variable Rate Transaction" means a transaction in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based upon, and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit or an "at-the-market offering", whereby the Company may issue securities at a future determined price, regardless of whether shares pursuant to such agreement have actually been issued and regardless of whether such agreement is subsequently canceled.

We agreed to file a proxy statement on Schedule 14A with the SEC no later than ten (10) days after the filing of the our Annual Report on Form 10-K for the period ended December 31, 2025, for the purpose of holding a meeting of stockholders (which may also be at the annual meeting of stockholders) at the earliest practical date after the date thereof, for the purpose of obtaining Stockholder Approval, with the recommendation of the our board of directors that such proposals be approved, and we shall solicit proxies from its stockholders in connection therewith in the same manner as all other management proposals in such proxy statement and all management-appointed proxyholders shall vote their proxies in favor of such proposals. If we do not obtain Stockholder Approval at the first meeting, we shall call a meeting every three months thereafter to seek Stockholder Approval until the earlier of the date Stockholder Approval is obtained or the Inducement Warrant is no longer outstanding.

The aggregate gross proceeds to the Company from the exercise of the Existing Warrants was approximately $7,500,000, before deducting offering expenses payable by the Company.

<u>Financial Advisor Agreement</u>

In connection with the Inducement Letter Agreement, on January 28, 2026, we entered into a letter agreement (the "Financial Advisor Agreement") with Maxim Group LLC (the "Financial Advisor"), pursuant to which (i) the Financial Advisor agreed to act as exclusive lead warrant solicitation agent on a "reasonable best efforts" basis in connection with the transactions contemplated by the Inducement Letter Agreement, and (ii) we agreed to pay the Financial Advisor an aggregate fee equal to 6.5% of the gross proceeds received by the Company from the exercise of the Existing Warrants. Additionally, we reimbursed the Financial Advisor for certain expenses and legal fees up to $20,000.

**RISK FACTORS**

*An investment in the securities offered under this prospectus involves a high degree of risk. You should carefully consider and evaluate all of the information contained in this prospectus and in the documents that we incorporate by reference herein before you decide to invest in our securities. In particular, you should carefully consider and evaluate the risks and uncertainties described below, as well as those set forth under the heading "Risk Factors" in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference in this prospectus. Our business, financial condition, or results of operations could be materially and adversely affected by any of these risks and uncertainties. Investors are further advised that the risks described below may not be the only risks we face. Additional risks that we do not yet know of, or that we currently think are immaterial, may also negatively impact our business operations or financial results. Any of the risks and uncertainties set forth in this prospectus and in the documents incorporated by reference herein, as updated by annual, quarterly, and other reports and documents that we file with the SEC and incorporate by reference into this prospectus, could materially and adversely affect our business, results of operations, and financial condition, which in turn could materially and adversely affect the value of our securities.*

<u>Risks Related to this Offering</u>

***The Selling Stockholder may choose to sell the shares at prices below the current market price.***

The Selling Stockholder is not restricted as to the prices at which it may sell or otherwise dispose of the Shares covered by this prospectus. Sales or other dispositions of the Shares below the then-current market prices could adversely affect the market price of our Common Stock.

***Neither we nor the Selling Stockholder has authorized any other party to provide you with information concerning us or this offering.***

You should carefully evaluate all of the information in this prospectus, including the documents incorporated by reference herein. We may receive media coverage regarding our Company, including coverage that is not directly attributable to statements made by our officers, that incorrectly reports on statements made by our officers or employees, or that is misleading as a result of omitting information provided by us, our officers or employees. Neither we nor the Selling Stockholder has authorized any other party to provide you with information concerning us or this offering, and recipients should not rely on this information.

***Investors who buy shares at different times will likely pay different prices.***

Investors who purchase Shares in this offering at different times will likely pay different prices and so may experience different levels of dilution and different outcomes in their investment results. The Selling Stockholder may sell shares of Common Stock underlying the Inducement Warrant at different times and at different prices..

***The issuance of Common Stock to the Selling Stockholder upon exercise of the Inducement Warrant may cause substantial dilution to our existing stockholders, and the sale of such shares acquired by the Selling Stockholder could cause the price of our Common Stock to decline.***

We are registering for resale by the Selling Stockholder of up to 9,467,456 shares of Common Stock that we may issue to the Selling Stockholder upon exercise of the Inducement Warrant. The number of shares of our Common Stock ultimately offered for resale by the Selling Stockholder under this prospectus is dependent upon the number of shares of Common Stock issued to the Selling Stockholder upon exercise of the Inducement Warrant. Depending on a variety of factors, including market liquidity of our Common Stock, the issuance of Shares to the Selling Stockholder may cause the trading price of our Common Stock to decline. Following receipt by the Selling Stockholder of Shares issued to the Selling Stockholder upon exercise of the Inducement Warrant, the Selling Stockholder may sell all, some or none of such Shares. The sale of a substantial number of shares of our Common Stock by the Selling Stockholder in this offering, or anticipation of such sales, could cause the trading price of our Common Stock to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire.

***Our management will have broad discretion over the use of the net proceeds received upon exercise of the Inducement Warrant, you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.***

Our management will have broad discretion over the use of proceeds from the shares of Common Stock received upon exercise of the Inducement Warrant. We intend to use the net proceeds primarily for acquisitions of additional fertility clinics and related businesses, capital expenditures, working capital, and general and administrative expenses. The net proceeds, if any, may be used for corporate purposes that do not improve our operating results or enhance the value of our Common Stock. The failure of our management to use these funds effectively could have a material adverse effect on our business or cause the market price of our Common Stock to decline.

**USE OF PROCEEDS**

We will not receive any proceeds from the sale of Shares by the Selling Stockholder pursuant to this prospectus. However, we may receive aggregate gross proceeds of up to $15,053,255 upon the Selling Stockholder's exercise of the Inducement Warrant. We intend to use the net proceeds primarily for acquisitions of additional fertility clinics and related businesses, capital expenditures, working capital, and general and administrative expenses.

We will pay all expenses associated with effecting the registration of the Shares, including filing and printing fees, the Company's counsel and accounting fees and expenses, costs associated with clearing the shares for sale under applicable state securities laws, and listing fees, , but excluding discounts, commissions, fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the sale or other disposition of the Shares.

**DIVIDEND POLICY**

We have never declared or paid any dividends on our Common Stock. We currently intend to retain all available funds and any future earnings for the operation and expansion of our business and, therefore, we do not anticipate declaring or paying dividends in the foreseeable future. The payment of dividends will be at the discretion of our Board and will depend on our results of operations, capital requirements, financial condition, prospects, contractual arrangements, any limitations on payment of dividends present in our future debt agreements, and other factors that our Board may deem relevant.

**Inducement Warrant**

*The following description of the Inducement Warrant is a summary and is qualified by reference to the Inducement Warrant and Inducement Letter Agreement.*

<u>Exercisability</u> 

The Inducement Warrant will be exercisable upon receipt of such approval as may be required by the applicable rules and regulations of the Nasdaq Capital Market (or any successor entity) from the stockholders of the Company with respect to issuance of all of the Inducement Warrants and the shares (the "Inducement Warrant Shares") of common stock upon the exercise thereof ("Stockholder Approval", and such date, the "Stockholder Approval Date") and have a term of five and one-half years from the Stockholder Approval Date. If a registration statement registering the issuance of the Inducement Warrant Shares under the Securities Act is not effective or available, the holder may, in its sole discretion, elect to exercise the Inducement Warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of Inducement Warrant Shares determined according to the formula set forth in the Inducement Warrant.

<u>Exercise Limitation</u>

A holder of the Inducement Warrant will not have the right to exercise any portion of the Inducement Warrant if the holder (together with its affiliates) would beneficially own in excess of 9.99% (the "Beneficial Ownership Limitation") of the number of shares of the Common Stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Inducement Warrant; provided, however, such holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of the Inducement Warrant held such holder. Any change in the Beneficial Ownership Limitation will be effective not be effective until the 61st day after such notice is delivered to the Company.

<u>Exercise Price Adjustment</u>

Subject to the aforementioned limitations, the exercise price of the Inducement Warrant is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications, or similar events affecting the Common Stock, and upon any distributions of assets, including cash, stock, or other property to our stockholders. In addition, subject to the rules and regulations of the Nasdaq Capital Market (or any successor entity), the Company may, at any time during the term of the Inducement Warrant, reduce the then current exercise price to any amount and for any period of time deemed appropriate by the board of directors of the Company.

<u>Subsequent Rights Offerings</u>

The Inducement Warrant provides that, if the Company conducts a pro rata distribution of rights, warrants or other securities to holders of its Common Stock, the holder of the Inducement Warrant will be entitled to participate in such offering as if it held the shares of Common Stock issuable upon full exercise of the Inducement Warrant immediately prior to the applicable record date. Participation is subject to the Beneficial Ownership Limitation, and any portion of such rights that would cause the holder of the Inducement Warrant to exceed those limitations will be deferred until such limitations no longer apply.

<u>Pro Rata Distributions</u>

While the Inducement Warrant is outstanding, the holder of the Inducement Warrant is entitled to participate in any dividend or other pro rata distribution of cash, securities, or other property to holders of Common Stock as if it held the shares of Common Stock issuable upon full exercise of the Inducement Warrant immediately prior to the applicable record date. Participation is subject to the Beneficial Ownership Limitations, with any portion of a distribution that would cause such holder to exceed such limitations deferred until the limitation no longer applies.

<u>Fundamental Transactions</u>

Upon the occurrence of certain fundamental transactions, including mergers, consolidations, asset sales, tender or exchange offers, recapitalizations or changes of control, the holder of the Inducement Warrant will be entitled, upon exercise of the Inducement Warrant, to receive the same form and amount of consideration that would have been received had the Inducement Warrant been exercised immediately prior to such transaction, with the exercise price appropriately adjusted as set forth in the Inducement Warrant. In certain fundamental transactions, the holder of the Inducement Warrant may instead elect to require the Company or a successor entity to repurchase the unexercised portion of the warrant for its Black-Scholes Value (as defined in the Inducement Warrant). The Inducement Warrant further provides for assumption by any successor entity and continuation of the Inducement Warrant holder's rights following a fundamental transaction.

**SELLING STOCKHOLDER**

This prospectus relates to the resale by Armistice from time to time of the Shares, consisting of up to 9,467,456 shares of Common Stock issuable upon exercise of the Inducement Warrant. We are registering the shares of Common Stock to permit Armistice to offer the Shares for resale from time to time. Armistice has not had any material relationship with us within the past three years, except as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Inducement Letter Agreement and the transactions contemplated thereby;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the participation of Armistice in a private placement (the "December 2025 Offering") that occurred on December 3, 2026, in which we issued shares of Common Stock, pre-funded warrants to purchase shares of Common Stock, and common stock purchase warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the participation of Armistice in our public offering (the "August 2023 Offering") of 5,486 units ("Units"), each consisting of either one share of Common Stock and two warrant to purchase, each to purchase one share of Common Stock, which consummated on August 8, 2023;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the amendment (the "July 2023 SPA Amendment") to that certain securities purchase agreement (the "July 2023 SPA") dated July 7, 2023, by and among us and the Armistice, pursuant to which, among other things, (I) the parties agreed to delete the Subsequent Equity Financing Provision (as defined in the July 2023 SPA Amendment) contained in the July 2023 SPA, (II) we agreed to pay the Armistice a fee of $1,000,000 as consideration of the Armistice's agreement to enter into the July 2023 SPA, and (III) we agreed to obtain the approval of our stockholders to lower the exercise price of certain warrants held by the Armistice as further described in the July 2023 SPA Amendment, noting each of the foregoing and the transactions in connection therewith have been consummated; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) the participation of the Armistice in a concurrent private placement and registered direct offering (the "March 2023 Offering") that occurred on March 27, 2023, in which we issued common stock purchase warrants to certain institutional investors.

The table below lists the Selling Stockholder and other information regarding the beneficial ownership (as determined under Section 13(d) of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder) of the shares of Common Stock held by the Selling Stockholder. The second column lists the number of shares of common stock beneficially owned by the Selling Stockholder, based on its ownership of shares of Common Stock, the Inducement Warrant, and any other warrants, as of January 30, 2026, assuming the exercise, of the Inducement Warrant and any other warrants held by the Selling Stockholder on that date, taking account of any limitations on exercise set forth therein.

Because the exercise price of the Inducement Warrant may be adjusted in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications, or similar events affecting the Common Stock, and upon any distributions of assets, including cash, stock, or other property to our stockholders, the number of shares that will actually be issued may be more or less than the number of shares being offered by this prospectus. The fourth column assumes the sale of all of the shares offered by the Selling Stockholder pursuant to this prospectus.

Under the terms of the Inducement Warrant, the Selling Stockholder may not exercise the Inducement Warrant to the extent (but only to the extent) the Selling Stockholder or any of its affiliates would beneficially own a number of shares of Common Stock which would exceed 9.99% of the outstanding shares of the Company. The number of shares in the second column reflects these limitations. The number of shares in the second column reflects this limitations, whereas the fourth column do not reflect this limitation The Selling Stockholder may sell all, some, or none of their shares in this offering. See "Plan of Distribution."

Beneficial ownership is determined in accordance with Rule 13d-3(d) promulgated by the SEC under the Exchange Act and includes shares of Common Stock with respect to which the Selling Stockholder has voting and investment powers. The percentage of shares of Common Stock beneficially owned by the Selling Stockholder prior to the offering shown in the table below is based on an aggregate of 6,961,095 shares of Common Stock outstanding as of January 30, 2026. The number of Shares that may actually be sold by the Selling Stockholder may be fewer than those being offered by this prospectus.

**Item 14. Indemnification of Officers and Directors.**

We are a Nevada corporation and generally governed by the Nevada Private Corporations Code, Title 78 of the Nevada Revised Statutes (the "NRS").

Section 78.138 of the NRS provides that, unless the corporation's articles of incorporation provide otherwise, a director or officer will not be individually liable unless it is proven that (i) the director's or officer's acts or omissions constituted a breach of his or her fiduciary duties, and (ii) such breach involved intentional misconduct, fraud, or a knowing violation of the law. Our articles of incorporation provide the personal liability of our directors is eliminated to the fullest extent permitted under the NRS.

Section 78.7502 of the NRS permits a company to indemnify its directors and officers against expenses, judgments, fines, and amounts paid in settlement actually and reasonably incurred in connection with a threatened, pending, or completed action, suit, or proceeding, if the officer or director (i) is not liable pursuant to NRS 78.138, or (ii) acted in good faith and in a manner the officer or director reasonably believed to be in or not opposed to the best interests of the corporation and, if a criminal action or proceeding, had no reasonable cause to believe the conduct of the officer or director was unlawful. Section 78.7502 of the NRS requires a corporation to indemnify a director or officer that has been successful on the merits or otherwise in defense of any action or suit. Section 78.7502 of the NRS precludes indemnification by the corporation if the officer or director has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court determines that in view of all the circumstances, the person is fairly and reasonably entitled to indemnity for such expenses and requires a corporation to indemnify its officers and directors if they have been successful on the merits or otherwise in defense of any claim, issue, or matter resulting from their service as a director or officer.

Section 78.751 of the NRS permits a Nevada company to indemnify its officers and directors against expenses incurred by them in defending a civil or criminal action, suit, or proceeding as they are incurred and in advance of final disposition thereof, upon determination by the stockholders, the disinterested board members, or by independent legal counsel. If so provided in the corporation's articles of incorporation, bylaws, or other agreement, Section 78.751 of the NRS requires a corporation to advance expenses as incurred upon receipt of an undertaking by or on behalf of the officer or director to repay the amount if it is ultimately determined by a court of competent jurisdiction that such officer or director is not entitled to be indemnified by the company. Section 78.751 of the NRS further permits the company to grant its directors and officers' additional rights of indemnification under its articles of incorporation, bylaws, or other agreement.

Section 78.752 of the NRS provides that a Nevada company may purchase and maintain insurance or make other financial arrangements on behalf of any person who is or was a director, officer, employee, or agent of the company, or is or was serving at the request of the company as a director, officer, employee, or agent of another company, partnership, joint venture, trust, or other enterprise, for any liability asserted against him and liability and expenses incurred by him in his capacity as a director, officer, employee, or agent, or arising out of his status as such, whether or not the company has the authority to indemnify him against such liability and expenses.

Our articles of incorporation provide for indemnification of our officers and directors to the fullest extent permissible under Nevada General Corporation Law, in accordance with the Company's Bylaws. Our Bylaws provide for indemnification of our officers and directors to the fullest extent not prohibited by the Nevada; provided however, that the Company may modify the extent of such indemnification by individual contracts with its directors and officers; and provided, further, that the Company shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law; (ii) the proceeding was authorized by the board of directors; (iii) such indemnification is provided by the Company, in its sole discretion, pursuant to the powers vested in the corporation under the Nevada General Corporation Law or; (iv) such indemnification is a result of the enforcement of a contractual right.

See "Item 17. Undertakings" for a description of the SEC's position regarding such indemnification provisions.

(7) Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, as amended, and will be governed by the final adjudication of such issue.

**SIGNATURES**

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Sarasota, State of Florida, on February 2, 2026.

Re: INVO Fertility, Inc. <br> Registration Statement on Form S-1

To whom it may concern:

We are special counsel to INVO Fertility, Inc., a Nevada corporation (the "**Company**") in connection with the issuance of this opinion which relates to a Registration Statement on Form S-1 (the "**Registration Statement**"), including a related prospectus filed with the Registration Statement (the "**Prospectus**"), with the Securities and Exchange Commission (the "**SEC**") under the Securities Act of 1933, as amended (the "**Securities Act**") relating to the registration under the Securities Act and the offering and sale by Armistice Capital Master Fund Ltd. ("**Armistice**" or the "**Selling Stockholder**") of up to 9,467,456 shares (the "**Shares**") of the Company's common stock par value $0.0001 per share (the "**Common Stock**") issuable upon exercise of a warrant (the "**Warrant**" and together with the Shares, the "**Securities**") to purchase shares of Common Stock issued by the Company to Armistice pursuant to an inducement letter agreement, dated January 28, 2026 between the Company and Armistice (the "**Inducement Letter Agreement**").

This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the Prospectus, other than as expressly stated herein with respect to the issue of the Securities and the securities issued upon exercise thereunder, as applicable.

In rendering the opinions set forth below, we have made such investigations and examined and relied upon originals or copies, certified or otherwise, identified to our satisfaction, of the Registration Statement, the Articles of Incorporation of the Company, as amended to date (the "**Articles of Incorporation**"), the Bylaws of the Company, as amended to date (the "**Bylaws**"), (i) the Company's Articles of Incorporation as currently in effect, (ii) the Warrant, (iii) the Inducement Letter Agreement, and (iv) such records of corporate proceedings, certificates of public officials and officers of the Company, and other certificates, instruments, and documents relating to the authorization and issuance of the Securities as we have deemed relevant and necessary for the opinions hereinafter expressed, and other documents as we have considered to be necessary or relevant for the purposes of the opinions hereinafter expressed. In addition, we have reviewed and relied upon certain of the Company's filings with the SEC, which are publicly available on the SEC's website at <u>sec.gov</u> and the SEC's EDGAR database located therein (the "**EDGAR Database**").

In rendering the opinions set forth below, we have relied, to the extent we deem such reliance appropriate, on certificates of officers of the Company as to factual matters regarding the Company, the Shares, the Warrant, the Inducement Letter Agreement, and the transactions described in the Registration Statement and the Prospectus that were not readily ascertainable by us. In all such examinations and in giving our opinion, we have assumed that all documents identified in the EDGAR Database as filed by the Company were filed with the SEC on the dates set forth on the EDGAR Database. We have further assumed the conformity to authentic original documents of all documents identified in the EDGAR Database as filed by the Company, the conformity to authentic original signatures of all conformed signatures set forth in the documents identified in the EDGAR Database as filed by the Company with the SEC, and the genuineness of all such signatures. We have further assumed the genuineness of all signatures (including .PDF, DocuSign, or other generally accepted electronic signatures and signatures delivered by facsimile), the legal capacity and competency at all relevant times of all natural persons signing any documents, the authenticity of all documents submitted to us as originals, the conformity to authentic original documents of all documents submitted to us as certified, authenticated, conformed, notarized, photostatic, facsimile, or electronic copies and the authenticity of the originals of such certified, authenticated, conformed, notarized, photostatic, .PDF, or facsimile copies. We have further assumed that all facts set forth in the official public records, certificates, and documents supplied by public officials or otherwise conveyed to us by public officials are complete, true, and accurate. We have also assumed that all facts set forth in any certificates supplied by the Company (including, without limitation, the board resolutions pursuant to which the Securities are to be issued) or by any purchaser are complete, true, and accurate. We have further assumed that (i) the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the Nevada Revised Statutes, and (ii) upon the issue of any of the shares of Common Stock, the total number of shares of Common Stock issued and outstanding will not exceed the total number of shares of Common Stock that the Company is then authorized to issue under its Articles of Incorporation.

It is understood that this opinion is to be used only in connection with the offer and sale of the Shares being registered while the Registration Statement is effective under the Securities Act.

These opinions are subject to the effect of federal and state bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent conveyance, and other laws relating to or affecting the rights of secured or unsecured creditors generally (or affecting the rights of only creditors of specific types of debtors), with respect to which we express no opinion.

These opinions are subject to the effect of general principles of equity, whether applied by a court of law or equity, including, without limitation, concepts of materiality, an implied covenant of good faith and fair dealing, upon the availability of injunctive relief or other equitable remedies, and the application of principles of equity (regardless of whether enforcement is considered in proceedings at law or in equity).

Based upon and subject to the foregoing assumptions, qualifications, and limitations, we are of the following opinions:

&nbsp;&nbsp;&nbsp;&nbsp;(1) The Warrant is the binding and enforceable obligation of the Company.

(2) If the Company obtains stockholder approval to issue the shares of Common Stock underlying the Warrant as may be required by the applicable rules and regulations of the Nasdaq Stock Market (or any successor entity), the shares of Common Stock to be issued upon exercise of the Warrant, when issued in accordance with the terms of their governing instruments and upon payment therefor, will be validly issued, fully paid, and non-assessable.

Our opinion is expressly limited to the matters set forth above, and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company, the Securities, or any other agreements or transactions that may be related thereto or contemplated thereby. We are expressing no opinion as to any obligations that parties other than the Company may have under or in respect of the Securities or as to the effect that their performance of such obligations may have upon any of the matters referred to above. No opinion may be implied or inferred beyond the opinion expressly stated above.

We are admitted to practice law in the State of California, and we render these opinions only with respect to, and express no opinion herein concerning the application or effect of the laws of any jurisdiction other than the existing laws of the State of California, the corporate laws of the State of Nevada (including Chapters 78 and 92A) of the Nevada Revised Statutes and applicable provisions of the Nevada constitution, but excluding local laws), and reported judicial decisions relating thereto.

We hereby consent to the use of this opinion as an exhibit to the Registration Statement and further consent to the use of our name under the caption "Legal Matters" in the Prospectus constituting a part of the Registration Statement. In giving the foregoing consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.

This opinion speaks only as of the date above written. We assume no duty to update, revise, or supplement this opinion or to communicate with you with respect to any change in law that comes to our attention hereafter.

Very truly yours,

The Company also agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company for or in connection with the engagement of the Financial Advisor by the Company or for any other reason, except to the extent that any such liability is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to have resulted primarily and directly from such Indemnified Party's gross negligence or willful misconduct.

These Indemnification Provisions shall extend to the following persons (collectively, the "**Indemnified Parties**"): The Financial Advisor, its present, former and future affiliated entities, managers, members, officers, directors, owners ,partners, stockholders, employees, legal counsel, agents, representatives and controlling persons (within the meaning of the federal securities laws), and its and their affiliated entities, managers, members, officers, directors, owners, partners, stockholders, employees, legal counsel, agents, representatives and controlling persons of any of them.

In order to provide for just and equitable contribution, if a claim for indemnification pursuant to these indemnification provisions is made but it is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) that such indemnification may not be enforced in such case, even though the express provisions hereof provide for indemnification in such case, then the Company shall contribute to the Losses to which any Indemnified Party may be subject (i) in accordance with the relative benefits received by the Company and its stockholders, subsidiaries and affiliates, on the one hand, and the Indemnified Party, on the other hand, and (ii) if (and only if) the allocation provided in clause (i) of this sentence is not permitted by applicable law, in such proportion as to reflect not only the relative benefits, but also the relative fault of the Company, on the one hand, and the Indemnified Party, on the other hand, in connection with the statements, acts or omissions which resulted in such Losses as well as any relevant equitable considerations. No person found liable for a fraudulent misrepresentation shall be entitled to contribution from any person who is not also found liable for fraudulent misrepresentation. The relative benefits received (or anticipated to be received) by the Company and its stockholders, subsidiaries and affiliates shall be deemed to be equal to the aggregate consideration payable or receivable by such parties in connection with the transaction or transactions to which the Agreement relates relative to the amount of fees actually received by the Financial Advisor in connection with such transaction or transactions. Notwithstanding the foregoing, in no event shall the amount contributed by all Indemnified Parties exceed the amount of fees previously received by the Financial Advisor pursuant to the Agreement.

Neither termination nor completion of the Agreement shall affect these Indemnification Provisions which shall remain operative and in full force and effect. The Indemnification Provisions shall be binding upon the Company and its successors and assigns and shall inure to the benefit of the Indemnified Parties and their respective successors, assigns, heirs and personal representatives.
