title: Pubertal development in male hypopituitarism.
abstract: The spontaneous or therapeutically induced pubertal development of 65 male patients with idiopathic hypopituitarism was analysed. Spontaneous puberty occurred in 82% of the patients with prepubertal isolated growth hormone deficiency and in 32.5% of those with impairment in the secretion of more than one pituitary hormone. Out of this group, 36 patients could be studied longitudinally. In 15 patients, the onset of spontaneous puberty was delayed, on average, 3.2 years. It started at a bone age of 10.36 +/- 1.25 "years" and followed a pattern similar to that of normal boys. Testosterone levels at each pubertal stage were not different from those of normal boys. Mean peak height velocity reached 7.27 +/- 1.82 cm/year. In 21 patients with gonadotropin deficiency, hCG treatment was started at a chronological age of 19.04 +/- 2.17 years and a bone age of 12.94 +/- 0.80 "years". Plasma testosterone attained normal adult levels in the majority of boys, while the development of sexual characteristics showed a wide variation. Mean growth velocity during the first year of hCG therapy reached 6.11 +/- 2.47 cm/year. Partial gonadotropin deficiency was diagnosed in two boys. Although testosterone seems today to be, for practical reasons, the replacement therapy of choice, hCG treatment is an alternative for hypopituitary patients with absent gonadotropin function.
