Ovarian Reserve Reduction With Surgery Is Not Correlated With the Amount of Ovarian Tissue Inadvertently Excised at Laparoscopic Surgery for Endometriomas

The aim of the present study was to evaluate the effect of laparoscopic cystectomy on ovarian reserve by means of anti-Müllerian hormone (AMH) serial measurements and to compare AMH values with the number of inadvertently removed follicles in histological specimens. Fifty-two women were enrolled: 34 patients with endometriomas (group 1) and 18 patients with other benign ovarian cysts (group 2). All patients underwent laparoscopic cystectomy performed by a single experienced surgeon. The AMH was measured before, and 1, 3, and 6 months after cystectomy in group 1, and before and 6 months after surgery in group 2. Preoperative AMH levels (mean [standard deviation, SD]) in group 1 (3.39 [2.43] ng/mL) were not significantly different from group 2 (3.74 [2.57] ng/mL; P =.68). In group 1, a significant decrease in AMH levels of 43.4% was observed at 1 month (1.93 [1.36]; P =.003), and of 63.1% at 3 months (1.25 [1.00]; P =.007) postoperatively. The AMH increased not significantly between the third and sixth months in group 1 (+9.4%). Six months after surgery, AMH was reduced by 59.3% compared to baseline values in group 1 (P =.012), and by 29.5% in group 2 (P =.200). A significant difference in the AMH decrease was present between bilateral and monolateral endometriomas (P =.006). There was no correlation between the reduction rate of AMH and the number of follicles inadvertently removed in patients with endometriomas (P =.669). In conclusion, AMH decreases significantly after surgical excision of ovarian endometriomas. The postoperative decrease does not appear to correlate with the amount of ovarian tissue inadvertently excised with the endometrioma wall. Similar content being viewed by others
