The impact of laparoscopic cystectomy on ovarian reserve in patients with unilateral and bilateral endometrioma.

Objective: To evaluate the effects of laparoscopic cystectomy on serum anti-Müllerian hormone (AMH) level as a marker of ovarian reserve in patients with endometrioma.

Methods: A prospective observational study enrolled patients aged younger than 40 years who were referred to a tertiary center in Tehran, Iran, between January 1, 2013 and December 31, 2014 to undergo laparoscopic cystectomy for ovarian endometriomas at least 30 mm in diameter, or regardless of size for patients with infertility, dysmenorrhea, dyspareunia, or dyschezia. Baseline and 6-month post-operative AMH levels were compared.
