Title: Does Endometrial Injury in the Non-Transfer Cycle Improve the IVF-ET Outcome in the Subsequent Cycle in Patients With Previous Failed IVF Cycles: A Randomized Control Trial
Brief Summary: Implantation of the human embryo is the limiting factor in the success of invitro-fertilization and embryo transfer(IVF-ET).We wanted to find out whether creating a local injury to the endometrium in the non-transfer cycle would improve the IVF-ET outcome in the subsequent cycle.We believe that the injury created causes release of substances which help in implantation.

* Basal levels of estradiol (≤ 80 pg/ml) and progesterone (≤ 1.6ng/ml) on day one of the cycle and a day three FSH level of \<12IU/L
* Patients can enter the study only once.
* Only the first IUI attempt will be included ( at the 2nd and 3 rd attempt progesterone could be administrated if it is necessary but these attempts will be excluded from the study)
* Normal HSG (maximum 3 months prior starting the stimulation).
* Donor sperm can be included

Exclusion Criteria:

* Endometriosis(≥AFS III)
B: 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
