LH peak / FSH peak ratio after GnRH test. Peak LH / peak FSH ratio after the GnRH test in patients with ambiguous genitalia (◆: without AR mutation, ■: with AR mutation) and normal control subject (△) in this study. Data of patients with mutation at ages of 1 yr 9 mo (# 25b: peak LH / peak FSH ratio=4.6) and 3 yr 8 mo (# 26: peak LH / peak FSH ratio =4.0) were obtained from patients 25 and 26, respectively.
