In multivariable analysis, AMH levels ≤ 1 ng/ml (OR 0.50, 95% CI 0.29–0.87, p = 0.014), TPMSC ≤ 5 mil (OR 0.37, 95% CI 0.19–0.723, p = 0.004), and a diagnosis of endometriosis, uterine malformation, or tubal obstruction (OR 0.54, 95% CI 0.33–0.89, p = 0.016) were associated with a decreased per cycle success rate (Table 3: Model 3). This evidence concerns the gene AMH and Abnormality of the uterus.
