Title: The Efficacy of Endometrial Biopsy on the Outcome of In Vitro Fertilization (IVF) /Intra-Cytoplasmic Sperm Injection (ICSI) Treatment (Endoscratch): A Feasibility Pilot Study
Brief Summary: This study aims to see if taking a small sample from the lining of the womb (the 'scratch') before starting in vitro fertilization (IVF) treatment can influence the chance of getting pregnant and having a healthy, term baby.

This study also aims to explore why an embryo is not accepted or indeed rejected by the lining of the womb. This will be analysed by carefully looking at the sample taken from the lining of the womb under the microscope and analysing the levels of natural killer (NK) cells. These cells are thought to regulate the implantation process and to be altered in some women with infertility and miscarriage.


Options:
A: Inclusion Criteria:

1. Pre-menopausal females between the ages of 18 and 42 years
2. Diagnosed with polycystic ovary syndrome (PCOS), using criteria adopted as the 2003 Rotterdam PCOS Consensus (2 out of 3, excluding other etiologies \[congenital adrenal hyperplasia, androgen-secreting tumors, Cushing's syndrome\])

   * Oligo- or anovulation
   * Clinical and/or biochemical signs of hyperandrogenism
   * Polycystic ovaries
3. Body mass index (BMI) of 18-39
4. Early follicular phase (Day 3) follicle stimulating hormone (FSH) \< 15 IU/L and estradiol (E2) within normal limits
5. Documented history of infertility (e.g., unable to conceive for at least one year, or for 6 months for women \> 38 years of age, or bilateral tubal occlusion or absence, or male factor but excluding severe male factor requiring invasive or surgical sperm retrieval. Donor sperm may be used.)
6. Transvaginal ultrasound at screening consistent with findings adequate for assisted reproductive technology (ART) with respect to uterus and adnexa
7. Signed informed consent

Exclusion Criteria:

1. Gestational or surrogate carrier, donor oocyte
2. Presence of any clinically relevant systemic disease (e.g., uncontrolled thyroid or adrenal dysfunction, an organic intracranial lesion such as a pituitary tumor, insulin-dependent diabetes mellitus, uterine cancer)
3. Surgical or medical condition which, in the judgment of the Investigator or Sponsor, may interfere with absorption, distribution, metabolism, or excretion of the drugs to be used
4. Two or more previous failed in vitro fertilization (IVF) cycles or in vitro fertilization (IVF)/assisted reproductive technology (ART) failure due to a poor response to gonadotropins, defined as development of 2 mature follicles
5. History of recurrent pregnancy loss, defined as more than two clinical losses
6. Presence of abnormal uterine bleeding of undetermined origin
7. Current or recent substance abuse, including alcohol or smoking \> 10 cigarettes per day
8. Refusal or inability to comply with the requirements of the Protocol for any reason, including scheduled clinic visits and laboratory tests
9. Participation in any experimental drug study within 30 days prior to Screening
10. Severe male factor requiring invasive or surgical sperm retrieval (e.g., microsurgical epididymal sperm aspiration \[MESA\], testicular sperm extraction \[TESE\])
11. Prior hypersensitivity to any of the protocol drugs
B: Inclusion Criteria:

1. Women ≥18 to ≤40 years of age, with one or more years infertility history, desirous of conceiving, regularly ovulating (defined as 9 or more menses per year), at initiation of participation.
2. Normal uterine cavity and at least one open fallopian tube confirmed by hysterosalpingography (HSG), sonohysterography, or laparoscopy/hysteroscopy in the last three years preceding enrollment into the study. An uncomplicated intrauterine non-IVF pregnancy and uncomplicated delivery and postpartum course resulting in live birth within the last three years will also serve as sufficient evidence of a patent tube and normal uterine cavity as long as the subject did not have, during the pregnancy or subsequently, risk factors for Asherman's syndrome or tubal disease or other disorder leading to an increased suspicion for intrauterine abnormality or tubal occlusion.
3. Evidence of ovarian function/reserve as assessed by day 3 (+/-2 days) FSH ≤12 IU/L within one year prior to study initiation.
4. Normal or corrected thyroid function within one year of study initiation.
5. Normal prolactin level within one year of study initiation.
6. In general good health, not taking any medications which could interfere with the study (e.g., FSH, insulin sensitizers).
7. Ability to have inseminations following hCG administration.
8. Male partner with total motile sperm in the ejaculate of at least 5 million sperm, within one year of study initiation.

Exclusion Criteria:

1. Currently pregnant or successful pregnancies within 12 months of initiating participation. Clinical intrauterine miscarriages prior to initiating participation, within ASRM guidelines: subjects over 35 must wait six months, while subjects under 35 must wait 12 months. No exclusion for biochemical pregnancies.
2. Undiagnosed abnormal uterine bleeding.
3. Suspicious ovarian mass.
4. Patients on oral contraceptives, depo-progestins, or hormonal implants (including Implanon). A two month washout period will be required prior to screening for patients on these agents. Longer washouts may be necessary for certain depot contraceptive forms or implants, especially when the implants are still in place. A one-month washout will be required for patients on oral cyclic progestins.
5. Known 21-hydroxylase deficiency or other enzyme defect causing congenital adrenal hyperplasia.
6. Type I or Type II diabetes mellitus, or if receiving antidiabetic medications.
7. Known significant anemia (Hemoglobin \<10 g/dL).
8. History of deep venous thrombosis, pulmonary embolus, or cerebrovascular event.
9. Known heart disease (New York Heart Association Class II or higher).
10. Known Liver disease (defined as AST or ALT\>2 times normal, or total bilirubin \>2.5 mg/dL).
11. Known Renal disease (defined as BUN \>30 mg/dL or serum creatinine \> 1.4 mg/dL).
12. History of, or suspected cervical carcinoma, endometrial carcinoma or breast carcinoma.
13. History of alcohol abuse (defined as \>14 drinks/week) or binge drinking of ≥ 6 drinks at one time).
14. Known Cushing's disease.
15. Known or suspected adrenal or ovarian androgen secreting tumors.
16. Allergy or contraindication to the treatment medications: AI, gonadotropins, CC or hCG.
17. Couples with previous sterilization procedures (e.g. vasectomy, tubal ligation) which have been reversed.
18. Patients with untreated poorly controlled hypertension defined as a systolic blood pressure ≥ 160 mm Hg or a diastolic ≥ 100 mm Hg obtained on two measures obtained at least 60 minutes apart.
19. Subjects who have undergone a bariatric surgery procedure in the recent past (\< 12 months) and are in a period of acute weight loss or have been advised against pregnancy by their bariatric surgeon.
20. Known moderate or severe endometriosis
21. Known polycystic ovarian syndrome as evidenced by anovulation or oligoovulation, hirsutism and/or elevated testosterone levels, and ovarian morphology on ultrasound examination.
22. Donated semen.
23. Couples in which either partner is legally married to someone else.
24. Medical conditions that are contraindications to pregnancy.
