AMH and endometriosis: In univariate and multivariate linear regression analyses of AMH reduction rates (Table 3), age (β = 0.686), ovarian cyst size (β = 1.483), location of ovarian cyst (β = 8.059), complexity of surgery (β = 4.670), and the severity of endometriosis (β = 9.953) were associated with the rate of decrease in AMH levels.
