This paper documents the case histories of 14 patients with hypogonadotropic hypogonadism and micropenis (penile length below 2.5 SD from the mean for the patient's chronological age, or for age corresponding to stage of sexual development). Nine of the patients were raised as males. Five of them received androgen for the purpose of stimulating penile growth: two realized normal adult penile length (-0.2 and -2.1 SD from normal mean length) whereas the other three had penile lengths significantly below the mean (-3.6, -4.6 and -5.2 SD from normal mean length). These data suggest that among hypogonadotropic patients with micropenis, those with prepubertal penile lengths between 2.5 and 3 SD below the mean may develop an adult penis of a length within the normal range. However, for those presenting with a shorter phallus, the expectation is that penile length will remain greater than 2 SD below the mean.
