Abstract

OBJECTIVE: To evaluate whether endometrioma is associated with a progressive decline in ovarian reserve, and to compare the rate of decline with natural decline in ovarian reserve. DESIGN: Prospective, observational study. SETTING: Tertiary university hospital, endometriosis clinic. PATIENT(S): Forty women with endometrioma and 40 age-matched healthy controls. INTERVENTION(S): Women with endometriomas who did not need hormonal/surgical treatment at the time of recruitment and were expectantly managed. Controls were age-matched, healthy women. All participants underwent serum antimüllerian hormone (AMH) testing twice, 6 months apart. Sexually active patients with endometrioma also underwent antral follicle count. MAIN OUTCOME MEASURE(S): Change in serum AMH levels. RESULT(S): Median (25th-75th percentile) serum AMH level at recruitment was 2.83 (0.70-4.96) ng/mL in the endometrioma group and 4.42 (2.26-5.57) ng/mL in the control group. The median percent decline in serum AMH level was 26.4% (11.36%-55.41%) in the endometrioma group and 7.4% (-11.98%, 29.33%) in the control groups. Twenty-two women with endometrioma who had antral follicle count (AFC) had median AFC of 10 (8-12) at recruitment and 8 (6.3-10) at 6 months. CONCLUSION(S): Women with endometrioma experience a progressive decline in serum AMH levels, which is faster than that in healthy women. CLINICAL TRIAL REGISTRATION NUMBER: NCT02438735.
