No drugs will be administered in the screening period. The screening visit should take approximately 60 minutes.\n\nDay 1 (15-minute visit): Blood pressure and heart rate will be measured prior to the administration of Relugolix 120 mg orally on an empty stomach.\n\nDay 2 (9 hour stay): Placement of IV and dosing of Testosterone Undecanoate 237 mg once with two ensures. The first dose of oral testosterone will be administered at 0900 (+/- 30 minutes) in the morning with two Ensures. After drug administration, subjects will have 10 ccs of blood drawn for the measurement of serum testosterone for the measurement of testosterone Predose, 0.5, 1, 1.5 2, 3, 4, 6, and 8 hours after the morning dose and will have the iv removed.\n\nDay 3 (9 hour stay): Placement of IV and dosing of Testosterone Undecanoate 237 mg once with two Ensures and 630 mg of oral Curcumin. The second dose of oral testosterone will be administered at 0900 (+/- 30 minutes) in the morning. After drug administration, subjects will have 10 ccs of blood drawn for the measurement of serum testosterone for the measurement of testosterone Predose, 0.5, 1, 1.5, 2, 3, 4, 6, and 8 hours after the morning dose and will have the iv removed.\n\nDay 4 (15-minute visit): Subjects will come into the clinic at 0900 for a 24-hour blood draw and adverse effect assessment.\n\nDay 28-42 (30-minute visit): Subjects will undergo a final assessment (physical examination, vitals and weight measurements and blood draw) on day 28-42. We will confirm at the follow-up visit that there has been recovery from Relugolix-induced hypogonadism (i.e., testosterone levels have returned to within 25% of baseline). If a subject has not recovered by this visit, he will be reassessed at 2-week intervals until recovery is documented. The total amount of blood drawn over the study protocol will not exceed 500 mL per subject.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 1\\. healthy male between 18 and 55 years of age\n* 2\\. agrees to not participate in another drug research study for the duration of this study\n* 3\\. agrees to not donate blood during the study\n* 4\\. subject provided written (personally signed and dated) informed consent before completing any study-related procedures\n* 5\\. subject able and willing to comply with the protocol\n* 6\\. subject able and willing to not take medications other than the study drug for the duration of the study\n\nExclusion Criteria:\n\n* 1\\. subject has poor general health, determined by medical history or physical exam\n* 2\\. subject have an abnormal evaluation on screening exam (consisting of serum chemistry, hematology and baseline hormone levels)\n* 3\\. subject have a known history or current use of alcohol drug or steroid abuse and/or the use of more than 3 alcoholic beverages per day\n* 4\\.
