title: Combined human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) treatment in gonadotropin-deficient males with pituitary dwarfism.
abstract: The effects of hCG-hMG treatment in 13 boys with pituitary dwarfism associated with gonadotropin deficiency, were assessed. No patients except one showed signs of puberty at a bone age of 13 years or above. The one patient with some signs of puberty did not become fully mature. The hCG-hMG was started at a mean age of 20.4 years. The hCG at a dose of 5,000 IU was injected intramuscularly twice a week and the hMG at a dose of 75 IU was given once a week at first. During treatment, the frequency of hMG injections was increased to twice a week in six patients who still had not produced normal sperm counts. After a mean duration of 19.23 months, spermatozoa appeared in eight patients, of whom four showed more than 20 x 10(6) sperm/ml. Among six patients who did not have normal sperm counts and had increased hMG injections, one produced a pregnancy and four achieved sperm counts of more than 35 x 10(6)/ml. One patient had refractory azoospermia. In 13 boys with growth hormone and gonadotropin deficiency, hCG-hMG treatment produced normal spermatogenesis in nine patients, one of whom fathered a girl. Thus, hCG-hMG treatment, especially twice-a-week injections of both hCG and hMG, appears to be effective for gonadotropin deficiency in males.
