Pre-IVF Treatment With a GnRH Antagonist in Women With endometriosis_temp

Inclusion Criteria9

• Women who plan to undergo IVF for treatment of infertility.
• Age ≥18 and <40 years at time of egg retrieval or signing informed consent.
• Documentation of diagnosis of endometriosis by surgical visualization of endometriosis (laparoscopy or laparotomy) or diagnosis by pathology within the last 10 years before the initial trial entry visit or documentation of ovarian endometrioma >2 cm or two or more smaller endometriomas that total >2 cm in diameter. If entry is based on the presence of an endometrioma, transvaginal ultrasound evaluation must document the same unambiguous endometrioma on two separate occasions in more than one menstrual cycle. Images will be printed or transmitted electronically and read centrally by investigators at Yale to assure uniform diagnostic criteria (classic ground glass appearance) are applied.
• Body mass index (BMI) of 18-40 kg/m2 (both inclusive) at screening.
• AMH > 0.5ng/ml, within 12 months of a fresh IVF cycle start. For frozen embryo transfers (FET) , AMH level eligibility criteria may not be met as long as the patient has at least one good quality blastocyst stored for the FET.
• No known uterine cavity abnormalities at time of screening. Uterine cavity assessment by sonohysterogram or hysteroscopy within 12 months of embryo transfer indicating absence of focal intracavitary pathology and hence establishing adequate cavity at the time of embryo transfer. Ultrasound or MRI features suggestive of adenomyosis will be acceptable for inclusion. Type 3 fibroids are allowed up to 4cm size.
• Presence of at least one ovary with no clinically significant abnormalities other than endometrioma. For eligible women with evidence of a hemorrhagic ovarian cyst, a repeat US will be needed in a subsequent menstrual cycle to ensure persistent cyst for patient to be deemed eligible.
• Negative urine or cervical swab for gonorrhea and chlamydia within 12 months of screening.
• Willing and able to comply with trial procedures, including reporting of obstetrical outcomes after delivery.
