A meta-analysis based on the random-effects model of these 6 studies showed a noteworthy rise of the AMH level in neonates of PCOS mothers compared with control groups of healthy mothers, with an overall SMD =0.62, 95% CI (0.28, 0.95), Q test p-value <0.0001, and I2 = 74%, suggesting heterogeneity among these studies (Fig. 2). This evidence concerns the gene AMH and polycystic ovary syndrome.
