RESUMO
This prospective study had the objective to compare anti-Müllerian hormone (AMH) serum levels among women with endometriomas and those with other benign ovarian cysts and verify a possible correlation between the AMH post-operative decline and the achievement of pregnancy. The study included 57 women undergoing laparoscopic surgery. Serum levels of AMH were measured preoperatively and at 6 and 12 months postoperatively. AMH serum levels decreased in both endometriomas and other benign cysts, but significant recovery was reported only in endometriomas (p = .029). Through an interview, information on reproductive outcome was obtained. The secondary endpoint was to identify other predictors of spontaneous pregnancy onset. After surgery 27 women attempted to conceive. At 18-months follow-up, 12 of them got pregnant, with a live birth of 37%. We did not record statistically significant differences in reproductive outcome between women with AMH serum levels lower and higher than 1.1 ng/ml (41.7 and 53.3% respectively). There was no statistically significant difference in AMH serum levels between pregnant and non-pregnant women, neither before nor after surgery. AMH did not appear to have a predictive role on reproductive outcome.
