Infertile men in the lowest AMH tertile had significantly lower sperm concentration (∆T3-1 16 mill/mL (228%); P < 0.001), sperm count (∆T3-1 55 million (262%); P < 0.001), motile sperm count (∆T3-1 28 million (255%); P < 0.001), progressive motile sperm count (∆T3-1 18 million (300%); P < 0.001), testis size (∆T3-1 2.7 mL (16%); P < 0.001), serum inhibin B (∆T3-1 72 pg/mL (59%); P < 0.001), inhibin B/FSH ratio (∆T3-1 48 (145%); P < 0.001), and higher FSH (∆T3-1 2.6 (38%); P < 0.001) than the tertile of infertile men with highest serum AMH. Here, BRD2 is linked to Infertility.
