Title: Fertility Kits with Sterile Syringes and Collection Jars, Method of Sterilization and Use

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority as a continuation-in-part to U.S. patent application Ser. No. 17/526,705, now allowed, that was filed on Nov. 15, 2021; and in which the disclosure is incorporated by reference herein in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to sets comprising fertility syringes and semen collection jars for use in at-home intracervical insemination (ICI), applicator kits, and methods of use. 
     BACKGROUND OF THE INVENTION 
     Intrauterine Insemination (IUI) requires delivery of washed semen via a syringe through the cervix and directly into the uterus; while Intracervical Insemination (ICI) requires delivery of unwashed semen only to the cervical opening. Methods and instruments for conducting IUI and ICI fertility treatments are well known in the art. IUI requires treatments within a clinical setting, to include taking oral and/or injectable fertility drugs, and the washing of semen. Treatment costs on average about $895; but it can run up to $4000 depending on the clinic (Gurevich, R.  What is Intrauterine Insemination,  published Nov. 11, 2020 on website VeryWellFamily). 
     A 2018 study showed that during non-medically induced ovulation, Intrauterine Insemination (IUI) and Intracervical Insemination (ICI) have the same live birth rate (Kop, P. A., Mochtar, M. H., et al. (2018). “Intrauterine insemination versus intracervical insemination in donor semen treatment”  The Cochrane database of systematic reviews,  1 (1)). 
     ICI is a much less expensive treatment (e.g., the cost of the kit shipped to a user&#39;s home). The additional preparation of washing semen, along with needing to be inside of a clinical setting, results in IUI being approximately 4 times the cost of ICI. Due to the high difference in cost, as well as the insignificant difference in live birth rate, it&#39;s been suggested that over the initial three months, ICI should be the preferred initial treatment (Kop, PAL, et al. (2015) “Intrauterine insemination or intracervical insemination with cryopreserved donor semen in the natural cycle: a cohort study”,  Human Reproduction,  30 (3)). 
     Fertility syringes for both IUI and ICI methods are well known in the art; but most available syringes are generally intended for use within a medical setting by a clinician for IUI treatments. IUI syringes are generally thinner and longer than ICI syringes in order to extend through the cervix for direct delivery of semen into the uterus. ICI syringes are generally round at the distal end to block the cervical opening to prevent the released semen from traveling backward into the vagina. ICI syringes can be difficult to handle by users who are not medical professionals, e.g. pushing the plunger in with one hand while lying down. 
     ICI kits occasionally include a semen collection jar in addition to the fertility syringe. Unfortunately, the jars normally comprise traditional round containers with inside seams or cracks where semen can become trapped, thus reducing the amount that can be transferred to the syringe. 
     Current sterilized syringes are often not designed for insemination, while at home insemination syringes are not sterilized. Research on the vaginal microbiome and diagnoses of infertility have becoming increasingly present in the art. This research demonstrates the need for sterilized at home syringes, designed for intracervical insemination within the art to reduce likelihood of introducing infection. (Xu et al., (2020) “Fertility factors affect the vaginal microbiome in women of reproductive age”  American J of Reproductive Immunology,  83 (4); Garcia-Velasco, J, et al. (2020) “The reproductive microbiome—clinical practice recommendations for fertility specialists”, RBMO, 41 (3): 443-453; Garcia-Velasco, J, et al. (2017) “What fertility specialists should know about the vaginal microbiome: a review”,  RBM online,  page 103-112; and Gupta, S, et al. (2019) “Crosstalk between Vaginal Microbiome and Female Health: A review”,  Microbial Pathogenesis,  136 (103696): 1-10). 
     What is needed in the art of at-home ICI treatments, is sterilized disposable fertility syringes and semen collection jars for use by non-medical professionals to significantly reduce the costs of treatment while increasing the efficacy in delivering the maximum amount of semen to the user&#39;s cervix. At a minimum, the fertility syringes should be easy to use with one-hand; the collection jars should be seamless inside; and the syringe structure should be able to deliver all of the semen to the target site while leaving a minimum amount in the syringe. Additionally, the kits comprising the syringes and the jars should be sterilized to prevent pathogens from hindering the user&#39;s fertility. 
     SUMMARY OF THE INVENTION 
     Various embodiments of the present invention comprise a fertility kit for performing self-insemination, comprising a container storing one to three sets of the disposable sterilized ICI fertility syringes and a semen collection jar, each wrapped in a pathogen proof plastic and having undergone sterilization. The present invention also includes methods of sterilization and methods of kit use. 
     Each fertility syringe comprises: an outer rigid tubular barrel and an inner plunger. The barrel comprises a curved distal end with a small circular distal opening, and a sealed proximal end, and an inner hollow tube housing the plunger. The barrel&#39;s proximal end also comprises two opposing circular members to fit a user&#39;s fingers; and a plunger flat end fitting in-between. The plunger distal end has a circular rubber with a tubular member that fits into the barrel curved end to push all the semen out while preventing a backflow. The collection jar comprises a sealable lid, and an inner surface comprising smooth seamless edges. Fresh or frozen, washed or unwashed semen is deposited into the jar, pulled into the syringe, and administered intra-cervically during a user&#39;s maximum monthly level of luteinizing hormone. 
     Various embodiments of the present invention further comprise an intracervical insemination (ICI) fertility kit for performing at home self-insemination, comprising at least one set (e.g. preferably three sets) of disposable: a) a plastic sterile fertility syringe; and b) a plastic sterile semen collection jar, individual wrapped sterile packing, which are shipped together in a package with instructions. 
     The sterile ICI fertility syringe comprises: a) an outer rigid tubular barrel comprising a curved distal end with a distal opening and a sealed proximal end, and said barrel enclosing an inner hollow tube with a narrowed distal opening joined to the barrel distal opening; b) the barrel sealed proximal end further comprising a handle combination comprising two opposing substantially hollow circular members able to fit a user&#39;s fingers; and c) a plunger positioned within the inner hollow tube and able to slide within to draw up and expel semen from the distal opening. 
     The plunger further comprises a distal end encircled by rubber seal positioned to tightly fit within (or flush to) the barrel curved distal end. And the plunger further comprises a tubular end distal to the rubber seal, said tubular end positioned to fit tightly within the tube narrowed distal opening to push all of the semen out of the distal opening. And the plunger further comprises a proximal end comprising a flat handle positioned to fit within the barrel circular members when the syringe is closed/retracted. And the plunger further comprises parallel ribs, divided into three sections of equal length, encircling and extending the length of the plunger. 
     The sterile semen collection jar comprises a plastic hand-held container and a sealable lid, and an inner surface comprising smooth seamless edges to prevent semen from being trapped within the seamless edges. It holds about 34 milliliter volume; and is round shaped on the outer bottom surface and inner bottom surface. In an embodiment, the semen collection jars comprise a screw top or snap on lid. With a screw top, threads on the lid match threads on the container-jar. 
     The ICI fertility kit further comprises a transparent or opaque plastic wrapper sealing one or more of the fertility syringes and semen collection jars to keep them sterile. The wrappers comprise pores able to pass air, gamma radiation, and ethylene oxide gas, but that are too small to permit the passage of pathogens (e.g. bacteria and viruses) into the wrapper. 
     The ICI fertility kit further comprises a container or box or package for shipping the one or more sets, said package comprising a printed instructions on a method of using the fertility kit, and/or a printed website link or QR code to the instructions. 
     In an embodiment, the ICI fertility kit may further comprise an ovulation calendar to track luteinizing hormone result levels; and/or luteinizing test strips. 
     Various embodiments of the present invention further comprise a kit enclosing a plurality of individually packaged sterile fertility syringes and semen collections jars, such as three sets thereof. If the kit comprises one set of syringe and collection jar, then a user will need three kits for a one-month treatment. If the kit comprises three sets of syringes and collection jars, then the user will only need one kit for one month of treatment. 
     In an embodiment, the semen collection jars comprise a screw top or snap on lid; and round edges on the outer surface and inner walls. The later prevents the semen from collecting in the jar&#39;s inner seams, thus making the majority of the semen able to be extracted from the jar into the fertility syringe. 
     The present invention further comprises a method of sterilization of a plurality of ICI syringes and collection jars, comprising: 
     1) sealing an ICI fertility syringe and a semen collection jar in a plastic wrap, wherein the syringe and the jar are in the same wrap or a different wrap, and the plastic wrap is non-penetrable to pathogens; 
     2) determining a sterilization dose level and duration, and setting a sterilization machine to the dose level, wherein the sterilization machine is ethylene oxide or gamma radiation; 
     3) placing a plurality of the wrapped syringes and the jars into sterilization machine, and exposing for at the determined dose level and duration; and 
     4) removing the plurality of wrapped syringes and jars from the sterilization machine, and placing one to three sets of the syringes and jars into a kit. 
     In an embodiment, the sterilization machine emits gamma radiation at a dose level up to 10,000 kilograys, preferably 20-50 kGy, and for a duration up to 24 hours. In an embodiment, the gamma radiation is from Cobalt 60. In another embodiment, the sterilization machine emits ethylene oxide up to 7 days duration. 
     In an embodiment, the sterilization machine emits ethylene oxide, and requires up to seven days processing. 
     The present invention further comprises a method of use of the kit disclosed herein to complete a one-month round of at-home fertility treatments, comprising the steps of: 1) providing a fertility kit housing one-three sets of sterile fertility syringes and collection jars; 2) determining a user&#39;s calendar date of displaying a maximizing luteinizing hormone levels; 3) receiving a fresh or frozen deposit of a semen sample within the collection jar; 4) holding an unwrapped, sterile fertility syringe vertically in the collection jar, and withdrawing all of the semen sample into the fertility syringe by pulling upward on the plunger; 5) while lying down, inserting the sterility syringe until it is flush with a user&#39;s cervical opening, then pushing the plunger one or two-handedly inward to release all of the semen sample into the cervix; 6) remaining lying down for at least a half hour; and 7) repeat steps (1)-(6) two times per month with the two remaining sets of syringes and jars. The treatments are done in three consecutive days. The first application is the day before the user has reached their maximum luteinizing hormone level for the month. The second application should be done on the day of the users maximum luteinizing hormone level, and the third application the day after the luteinizing hormone peak. 
     One aspect of the present invention is to provide a fertility syringe that is able to reach the cervical opening to provide targeted delivery of the semen directly to the cervical opening. This decreases the distance the semen needs to ‘swim’ to meet the egg. This is especially helpful for anyone experiencing male factor infertility, such as decreased semen motility or abnormal semen morphology. 
     Another aspect is that the fertility syringes are sterilized, and then packaged in sterile, plastic wraps. Scientific studies have linked certain bacterial species present in the vaginal microbiome to women with unknown (or idiopathic) infertility. The sterilized syringes of the present invention bypass these bacteria if present. Sterilized syringes also decrease the introduction of new bacteria into the microbiome, which can impact fertility. 
     Another aspect is that the large opening of the syringe tip combined with the scientifically engineered plunger cap, works to minimize semen sample waste so that the maximum amount of semen is dispersed from the syringe leaving a minimal residual semen within the syringe. 
     Another aspect is a novel syringe with an elongated and curved distal tip, with a circular opening to maximize a user&#39;s chances of impregnating by reaching to, and increasing the surface area contact with the user&#39;s cervix. The curved end allows insemination to occur directly at the cervical opening. 
     Another aspect is the structure of the plunger and barrel distal end to create a one-way like valve that prevents the semen from remaining in the syringe when the plunger is completely pushed in. This is due to the plunger&#39;s funnel like end and pointed tip, pushing all semen out of the barrel&#39;s hollow tube hole, which is aligned with the barrel outer hole. The plunger&#39;s pointed tip plugs these holes to prevent any backwash of the semen. 
     Another aspect is the novel syringe&#39;s combination handle that allows the user to hold the syringe one-handedly, while pushing the plunger completely in. The user holds the syringe with their index and middle finger through the barrel circular loops, and pushes the plunger in with their thumb; and while lying on their back, preferably on a pillow or with their hips otherwise elevated. 
     Another aspect is the collection jars hold unwashed, fresh or frozen semen. 
     The objects features and effects of the invention are described in detail below with accompanied drawings and embodiments. The aforementioned objects of the present invention are attained by an apparatus and method that functions for fertilization. Other objects, advantages and novel features of the present invention will become readily apparent from the following drawings and detailed description of preferred embodiments.

       FIGS.  1 - 6    illustrate one exemplary embodiment of the fertility kits of the present invention:  FIGS.  1 - 4 C , syringe  10 ;  FIG.  5    a semen collection jar  40 ; and  FIG.  6    a fertility kit  50 . 
     Syringe 
     As illustrated in  FIGS.  1 - 4 C , each fertility syringe comprises a proximal end  35  and a distal end  30 , and the general components of: an outer barrel  12  with a hollow tube  20  centered along the barrel length; and a plunger  22  that easily slides back and forth through tube  20 . 
     The syringe also has a handle unit combining: circular members  26  attached to the barrel  12 ; and with a flat head end  36  attached to the plunger  22 . This combination allows a user (if necessary), to hold and control the movement of the plunger using just three fingers: thumb, index, and middle finger. Preferably the user has both hands available to stabilize the syringe. 
     In an exemplary embodiment, syringe  10  is about 125-130 mm in length and about 72 mm in width due to the handle loops  26  (but about 20 mm at barrel  12 ); and the syringe is made of disposable plastic that is able to be sterilized via exposure to gamma radiation or ethylene oxide. 
     Syringe Barrel 
       FIG.  3 A  is an illustration of an exemplary side view of the outer surface of barrel  12 ; and  FIG.  3 B  is a longitudinal cross-section view of  FIG.  3 A , rotated ninety degrees. In an exemplary embodiment, the syringe&#39;s barrel comprises: an outer rigid tubular barrel  12 , a center hollow tube  20 , and a curved distal end  14  (e.g. generally half oval shaped and about 26 mm in length). This distal end further comprises a small circular distal opening 16 (e.g. about 2.4 to 3 mm in diameter). 
     As shown in the cross-sectional view of  FIG.  3 B , barrel  12  may be made of solid opaque material  13  (except for the hollow tunnel  20 ). In another embodiment, the space between barrel outer body  12  and tube  20  is hollow. 
     The middle of the barrel houses a hollow tube  20  with inner walls  21 , and having a cross-sectional area of about 10 mm in diameter, while the entire barrel has a cross-sectional area of about 20 mm, in one exemplary embodiment. 
     Tube  20  distal end tapers inward to form a funnel-like shape that matches the distal end  52  of the plunger  32 ,  34  (see  FIGS.  4 A- 4 D ). This funnel member either: 1) forms a small narrowed distal opening  31 , which aligns and may be joined to the barrel distal opening  16 ; or 2) joins directly to distal opening  16 . Either (1) or (2) allows semen to be pulled into and ejected from the hollow tube  20  while the plunger ends  32 ,  34  can plug barrel hole  16  to function as a one-way valve after the semen is ejected. 
     The barrel proximal end comprises a perpendicularly positioned disc  18  with a hole  15  equal to the plunger diameter, and forming a sealed proximal end that prevents plunger  22  from fully detaching from barrel  12 . Proximal end  18  further comprises one part of the handle combination, two opposing loop members  26 . 
     Plunger 
       FIG.  4 A  illustrates a side view of plunger  22 ;  FIG.  4 B  is a longitudinal cross-sectional view thereof; and  FIG.  4 C  is a magnified view of the plunger&#39;s distal end. Plunger  22  slides smoothly distally and proximally through the barrel hollow tube  20 , while contacting the tube&#39;s inner walls  21  to push all the semen out of the distal opening  16 . In an embodiment, the length of plunger  22  is about 135 to 137 mm, the diameter is about 9.5 mm, and the diameter of tube  20  is about 10 mm. 
     As illustrated in the close-up view of  FIG.  4 C  and cross-sectional view  4 D, plunger  22  further comprises on the distal end a circular rubber end  32  (e.g., a plug), with or without individual rings  41  (e.g., 3 total) that are wider than the plunger&#39;s diameter  43 , and taper downward/inward distally; and may further comprise a tubular extension  34  (e.g., a pin or “pointed tip”) adjoined distally to the rubber ring(s)  32 . Plunger distal end ( 52 ) comprising the rubber end  32  and pin  34  are within a funnel-like shape distal end  45 , and are sized to fit tightly into the both the barrel&#39;s hollow tube  20  funnel-like shape distal end  31  and the barrel&#39;s distal end opening  16  (e.g., see  FIG.  3 B ). This enables the expulsion all of the semen from the syringe, while also functioning as a one-way valve (e.g., the opening  16  is too small and blocked by  32 ,  34  so as to prevent any semen from re-entering the syringe). In an embodiment, plunger  22  further comprises a plurality of parallel ribs  23  (e.g., 5 total) evenly spaced around the plunger, and extending its length (proximal to distal). Plunger  22  may also be divided into multiple sections  25  along its length, e.g., three sections of about equal length, with a flat disc  17  joining two aligned sections  25 . Parallel ribs  23  and sections  25  facilitate plunger  22  to slide smoothly back and forth through tube  20  by minimizing the surface contact area, and by making the plunger more rigid. 
     Syringe Handles 
     As illustrated in  FIGS.  1 - 3 B , the syringe handle combination comprises: 1) the barrel&#39;s two looped rings  26 ; and 2) the plunger&#39;s flat end  36 , which is rotated 90 degrees to fit in-between loops  26 . Barrel loops comprise two opposing substantially hollow, circular members  26  able fit a user&#39;s index and middle fingers. In an embodiment, the inner diameter of circular members  26  is about 25 mm; and the circular members  26  do not form a complete circular, but rather about 75%. In another embodiment, they form a complete hollow circle. 
     In an embodiment, the shape of circular members  26  also tapers wider while extending outward from barrel proximal end  18 . As shown in  FIG.  2   , at end  18  the minimum width  27  of a circular member  26  is about 2-3 mm; and the maximum width  29  is about 15 to 16 mm. In another embodiment, circular members  26  have a uniform width the entire length. In all embodiments, plunger flat end  36  is rotated to fit in-between circular members  26  when the plunger is completely pushed in via a user&#39;s thumb on flat end  36 . Plunger flat end  36  may also comprise a variety of substantially thin about 2 mm flat shapes, such as rectangular, or oval, or the exemplified, center circle with opposing rectangular ends. 
     Collection Jars 
       FIG.  5    is an illustration of an exemplary semen collection jar  40  comprising a round hand-held container  42  and a sealable snap-on lid  44  with inner rim  41 , Container  42  has an inner surface  46  comprising smooth seamless edges  48  on the outer surface  48   o  and on the inner surface  48   i  to prevent semen from being trapped within the seamless edges. In one embodiment, jar  40  can hold up to 30 milliliters volume, and it about 50 mm width on the lid, and about 40 mm height. In an embodiment, the collection jar is made of disposable plastic that is able to be sterilized via exposure to gamma radiation or ethylene oxide. 
     ICI Fertility Kits 
     In an exemplary embodiment, kits  50  of the present invention comprise: at least one set (e.g., three sets total) of sterile fertility syringes  10  and sterile collection jars  40 , which are shipped in one container (e.g., a substantially rectangular shaped, recyclable, cardboard box  50 ). For example, one kit comprises one treatment with one collection jar  40  and one packaged syringe  10 . A user would buy three kits for one month of treatment. In another embodiment, three sets of collection jars and syringes come in the same package. 
     Each fertility syringe is individually packaged with a transparent or opaque plastic wrapper  60  to keep the syringe sterile. In another embodiment, two or three fertility syringes are sealed within one plastic wrapper  60 . Likewise, each jar is individually packaged with a transparent or opaque plastic wrapper  61  to keep the jar sterile. In another embodiment, two or three jars are sealed within one plastic wrapper  61 . In another embodiment, one syringe and one jar are within each plastic wrapper. Wrappers  60 ,  61  of the present invention are also known in the medical device industry as C-packs, and are made in compliance with ISO 11607-1:2019—“Packaging for terminally sterilized medical devices—Part 1: Requirements for materials, sterile barrier systems and packaging systems”. In an embodiment, that C-pack is made of Tyvek™ with pores that allow air, ethylene oxide, and gamma radiation to pass through, but not pathogens (e.g. bacteria, fungi, viruses, etc.). The kits may further comprise printed instructions 62 and/or posted instructions on a website link or QR code 64 to a website that is printed on the outside or inside of the shipping box. Instructions may further comprise a printed calendar, a website link, or a QR code for downloading a calendar of the present invention for a user to track their ovulation cycle. 
     Ovulation Calendars and Luteinizing Hormone Strips 
     The ovulation calendar ( FIG.  7 A,  70   ) and luteinizing hormone test strips ( FIG.  7 B,  80   ) (also known herein as “ovulation test strips”) are used to determine the optimal time for the user to attempt insemination, which occurs when the user is ovulating. In an embodiment, the ovulation calendar and test strips are in the same kit as the syringes and jars; and in another embodiment, they are mailed separately. 
     An exemplary luteinizing hormone (LH) test strip  80  is illustrated in  FIG.  7 B  and comprises: a thin rectangular paper that is dipped on end  82  into a cup of the user&#39;s fresh urine at a level not to exceed the maximum line. After waiting about 5 minutes, at least one line  84  appears in the middle of the strip  80 . If only one line appears, this is the “control” and the results are negative for LH. If two distinct separate lines appear, as illustrated in  FIG.  7 B , then the first line from end  82  is LH, and the second line from end  82  is the control line, and thus the results are positive for LH. 
     In an embodiment, the ovulation calendar is a paper table, or an online table able to receive and save user input (e.g. text and images); and comprising columns, e.g.: cycle date  72 ; date of recording  73 ; time of recording  74 ; intercourse  75 ; LH test strip image  76 ; “+/−”  77 ; and Notes  78 . 
     Cycle date  72  refers to menstrual cycle day, wherein “CD1” is the first day of onset. Intercourse  75  refers to whether the user had intercourse on the day of recording  73 . LH  76  refers to the luteinizing hormone (LH) test strip identification number or a photo of the strip test results; and “+/−”  77  refers to whether the LH test strip results were positive or negative for the presence of LH. The user can also add notes  78 , such as how they are feeling—extreme fatigue, cramps, etc. Once the user begins to see their LH levels rise, they should test 3 times a day to determine when they reach their peak LH level, as indicated when the LH starts to drop again. They should then use kit  60  is inseminate three days in a row: when the think they are about to reach their peak LH level; the day of the peak; and the day after. The ovarian egg is released about 24 hours after the peak LH level, and it can only be fertilized by the semen deposited using the syringe for the next 24 hours. So, there is only about a 48 hour window to optimize the user&#39;s chance of a pregnancy occurring. 
     Method of use of Kits 
     The method of use of kits  50  comprise the user first determining their ovulation cycle. This can be done using a calendar downloaded herein, and/or by using a third-party test kit or strips for measuring their luteinizing hormone level (e.g., a non-digital ovulation predictor kit—OPK). A user first determines when they are near their monthly maximum luteinizing hormone level by using the ovulation calendar ( FIG.  7 A,  70   ) and luteinizing hormone test strips ( FIG.  7 B,  80   ). In an embodiment, the ovulation calendar and test strips are in the same kit as the sets of syringes and jar; and in another embodiment, they are mailed separately. 
     Then semen donor deposits a fresh semen sample, or the user can use a recently thawed semen sample, that is deposited into a clean, sterile semen collection jar  40  and sealed closed. 
     The user then removes the lid  44 , unwraps a sterile syringe  10 , and positions the syringe vertically in collection jar  40 . The user then pulls up on plunger  22  until all of the semen is within the syringe. In an additional embodiment, the user may re-use the syringe while still lying down, so as to inject all of the semen remaining in the jar (e.g., two or more consecutive injections). The syringe distal end is not laid down or touched in between injections. 
     Then while lying down and holding the syringe in their dominant hand using their index and middle fingers inserted into syringe loops  26 , the user inserts the distal end of the syringe into their vagina until it is flush with their cervical opening. They then push the plunger handle  36  inward or distally with their thumb to release all of the semen sample into their cervical opening (e.g., plunger distal ends  32 ,  34  are against barrel hole  16  and the plunger cannot further move distally). After administering the semen sample or specimen, the user should remain lying down for at least a half hour. 
     In an embodiment, each kit  50  comprises three sets of syringes  10  and collection jars  40 ; for use the day before, of, and after ovulation, as indicated by a user&#39;s maximum luteinizing hormone strips to test. Hence, the user should administer a semen sample during these three days (i.e. day before peak, day of peak, day after peak). If a pregnancy does not result, the user can repeat the process in a subsequent month. As with all forms of infertility treatment, it could take 3-6 months in order for the user to become pregnant with this method of ICI. 
     Method of Kit Sterilization 
       FIG.  8    is a flowchart of user steps in terminally sterilizing the syringes and jars of the present invention. They are “terminally sterilized” in accordance with the International Organization of Standardization (ISO) regulation ISO 11607, which is hereby incorporated by reference in the entirety. The syringes and jars of the present invention are “terminally sterilized” by undergoing a sterilization process while the product is already within its packaging (C-pack; wrapper  60 ,  61 ), which includes a sterile barrier system. A sterile barrier system is the minimum layer of protection that ensures sterility. 
     The “packaging system” as a whole is a combination of the sterile barrier system and any protective packaging (e.g. kit box) used to prevent damage to the sterile barrier system or the device. Terminally sterilized devices are sterilized using an agent that can penetrate their packaging system, such as ethylene oxide or gamma radiation. In an embodiment, the sterile barrier system comprises Tyvek™ material (a polypropylene blend) completely enclosing and sealing off at all seams the syringe and jar, in the same or different wraps ( FIG.  8   , step  810 ). Other materials well known in the art for use in the C-packs are also envisioned within the scope of the present invention, wherein the type and density of material largely determines that dose level and duration of sterilization (“Gamma Sterilization of Medical Devices”, FDA MEDICAL DEVICE ADVISORY MEETING NOV. 6, 2019, table “Plastics Comparison”). For example, polyesters can sustain up to 10,000 kilogray (kGy), while polypropylene only requires up to 50 kGy. 
     Methods of sterilizing medical devices using ethylene oxide or gamma radiation are well known in the art. In the sterilization of medical devices via exposure to ethylene oxide, the exposure conditions used are those required as listed in ANSI AAMI ISO 11135:2014, and ANSI AAMI ISO 10993-7:2008(R)2012. Ethylene oxide sterilization requires three phases: preconditioning; chamber cycle; and aeration (e.g. see Reisbacher, S, “Introduction to Ethylene Oxide Sterilization and Regulatory Updates”, 22 May 2019, pages 1-54). For example, preconditioning is performed at about 35-45 degrees Celsius and about 45-75% relative humidity; the chamber cycle is performed in cycles up to about 850 mbarA; the aeration is performed at about 35-50 degrees Celsius with forced circulation. In another embodiment, the temperature is between about 37 to 63 degrees Celsius, or about 104-140 degrees Fahrenheit; at a fixed pressure; concentration of about 500-800 mg/L and inversely dependent on the temperature; and exposed for about 2-10 hours, and aerated for about 7-10 days. 
     The gamma sterilization process is significantly different than the ethylene oxide process, and it starts by placing the source of radiation (usually Cobalt 60, but sometimes Caesium 137) in a radiation-shielded room. Packaged medical devices are then brought in using a conveyance system and circulated around the source of radiation to expose all sides of the product to the gamma rays. 
     In contrast to sterilization methods like ethylene oxide (EO), gamma irradiation does not require strict humidity, temperature, or pressure controls. The gamma sterilization process also does not significantly increase the temperature of the products being treated, making it ideal for sterilizing heat sensitive devices. 
     Radiation sterilization is performed under ISO 11137-1, which covers gamma, x-ray, and e-beam. In an embodiment, gamma radiation is performed on a plurality of syringes and jars at ambient temperature up to 20 degrees Celsius; for up to 24 hours; at a dose level of about 20-50 kilogray (kGy) ( FIG.  8   , step  820 ); and no requirement for fixed pressure. 
     Sterilization dose determination is performed by methods outlined in ISO 11137-1 and 2. The minimum dose [or sterilization dose (Dster) [as defined in ISO 11137] is the minimum dose defined to achieve the desired sterility assurance level, typically SAL 10 −6 . The minimum dose is established to be in accordance with ISO 11137-2. 
     A maximum dose must also be established and not exceeded during gamma sterilization because gamma rays have the potential to break down the polymers that are used in many single-use medical devices that require sterilization. ISO 11137-2 offers three related methods for establishing a radiation dose that meets both these requirements. The first two methods are similar to each other and involve determining the natural bioburden—the number of microorganisms on a product—and verifying the appropriate dose via sterility testing. These methods are designed to be used with products that come in large batches and require at least 100 units of the product. The third method, known as VDmax, is used for products that are made in smaller batches, when grouping hundreds of devices together is not feasible. Instead of determining the minimum dose required to reach SAL 10 −6 , this method tests a predetermined dose: either 25 kGy or 15 kGy for products with a lower tolerance for gamma rays. 
     In an embodiment, dose mapping may be required, and is performed in accordance with ISO 11137 rules and the International Atomic Energy Agency (IAEI) rules—e.g. see “Guidelines for the Development, Validation, and Routine Control of Industrial Radiation Processes”, the entirety of which is incorporated herein by reference. 
     In an embodiment, up to about 500 wrapped syringes and 500 wrapped jars of the present invention that are C-packaged, are placed into large cardboard boxes and placed on a pallet, and then placed into a gamma radiation device (e.g. Steris™ Corporation, Cobalt-60 gamma radiation device, at about 25 kGy, and at room temperature) ( FIG.  8   , step  830 ). The pallet is rotated around the gamma beam for up to  24  hours, then one to three sets of the sterilized, wrapped syringes and the sterilized, wrapped jars are placed in each kit ( FIG.  8   , step  840 ) as shown in  FIG.  6   . 
     As shown in  FIGS.  7 A and  7 B , an ovulation calendar  70  and/or luteinizing hormone strips  80  are added to the kit, or preferably shipped separately.
