Testicular hormone concentrations by age for individual males with XYY (solid black) and controls (open circles) and the corresponding regression lines. (a) Testosterone had a sigmodal relationship with age that was similar between cases and controls (p = .89). (b) Inhibin B was associated with a pubertal rise in controls but not for males with XYY, resulting in a significant group difference in the relationship of inhibin B and age (p = .004). (c) Anti-mullerian hormone (AMH) declined with age for both cases and controls, and there was a significant difference between XYY and controls for this relationship (p = .010)
