摘要
ObjectiveTo investigate changes in serum anti-Mullerian hormone (AMH) concentrations following ovarian cyst surgery, and predictors of these changes. DesignProspective cohort study with follow up at 3 and 6months. SettingUniversity hospital. PopulationWomen of reproductive age scheduled for ovarian cyst surgery. MethodsWomen were recruited between March 2011 and March 2012 (n=75). Serum AMH concentrations were measured preoperatively and at 3 and 6months postoperatively. Main outcome measuresChanges in AMH after surgery and predictors for these changes. ResultsAfter surgery, median AMH levels decreased significantly from 2.7g/L (0.2-16.9) to 1.6g/L (0.2-9.9) at 3months and were still low, 1.6g/L (0.2-8.3) at 6months (both p<0.001). In patients with unilateral cysts, a significant and more rapid AMH decrease was seen after enucleation of endometriomas (n=19) vs. dermoid cysts (n=22) (p=0.010). The reduction was long-lasting at 6months. In a multivariate regression analysis, a higher baseline AMH concentration was predictive of AMH reduction at 3 [odds ratio (OR) 1.9, 95% CI 1.1-3.1] and 6months postoperatively (OR 2.5, 95% CI 1.2-5.2). Women with normal or elevated baseline AMH presented with a significant reduction of -23% and -43% at 3 and 6months, respectively, whereas women with low or very low AMH had minimal or no changes over time. Patient's age, cyst size, duration of surgery or intraoperative bleeding were not predictive of a postoperative AMH decrease. ConclusionsReduction of AMH was of greater magnitude and longer duration after enucleation of endometriomas and in women with normal and high preoperative AMH levels.
