The investigators' central hypothesis is that in infertile woman with endometriosis undergoing in vitro fertilization-embryo transfer (IVF-ET), live birth rates will improve in those pretreated with GnRH antagonist compared to those not pretreated with GnRH antagonist.", 'detailedDescription': "Infertility is a common complication of endometriosis; while IVF successfully treats endometriosis-associated infertility, pregnancy rates are diminished compared to other etiologies of infertility. The study's long- term objectives are to better identify and treat endometriosis related infertility. The investigators' central hypothesis is that in infertile woman with endometriosis undergoing in vitro fertilization-embryo transfer (IVF-ET), live birth rates will improve in those pretreated with GnRH antagonist compared to those not pretreated with GnRH antagonist. The use of gonadotropin releasing hormone (GnRH) agonist prior to IVF has been suggested to improve success, however studies have been small and rarely reported live birth rates. Further, use of this approach is limited by the long treatment time required. Recent approval of an oral GnRH antagonist for endometriosis provides a novel option for women with endometriosis who are undergoing IVF. This agent avoids parenteral administration and the prolonged delay in initiation of action as was seen with GnRH agonists. There have been no studies on the efficacy of GnRH antagonists for the treatment of endometriosis-related infertility. The investigators propose a clinical trial of oral GnRH antagonist pre-treatment for women with endometriosis who are undergoing IVF, with a primary outcome of live birth rate. Participants will include those who agree to be randomized and those who do not want to be randomized. Those who agree to be randomized will be randomly assigned to either the elagolix group or placebo group. Those who do not want to be randomized can choose either the active treatment elagolix and follow the same procedures as those agreeing to be randomized or continue their ongoing or planned IVF and follow standard of care (SOC) (SOC IVF) if they do not want to delay the IVF procedure."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '40 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.

Use of aromatase inhibitors, danazol or hormonal contraceptives (Including combined oral contraceptive pill, progestin-only pill, transdermal patch or contraceptive ring, or double barrier contraception) within 1 month of study start.\n5. Pregnancy greater than 8 weeks in length within the last 6 months.\n6. Number of previous IVF/ICSI attempts ≥3 unsuccessful (negative pregnancy test).\n7. Presence of hydrosalpinx measuring \\>2cm on ultrasound, untreated endometrial polyps or intrauterine adhesions.\n8.

(CIN1 or HPV allowed to participate in the study, CIN2 excluded unless treated and cleared, CIN3 excluded).\n9. History of malignancy within 5 years of the start of screening, except for treated basal cell carcinoma and squamous cell carcinoma of the skin.\n10. Any thoughts of suicide in the last 12 months per self-report, or documented in the electronic medical record (EMR).\n11. Hypersensitivity to the study drugs.\n12. Planned surgical treatment of endometriosis or planned surgery in the abdominal-pelvic area within the duration of the trial.\n13. Untreated abnormal prolactin or TSH\n14. Any conditions that preclude pregnancy.\n15. Patients with a known history of a low-trauma fracture or other risk factors for osteoporosis or bone loss.\n16. Patients with cirrhosis or abnormal LFTs per self report or documented in the electronic medical record (EMR).\n\n * Exclusion criteria number 1,2, and 3 are not required to be met by individuals in the standard of care arm of the study.
