Induction of fertility in a man with hypogonadotropic hypogonadism with very low seminal volume.

Pituitary function studies were performed on a 31-year-old man who had oligospermia and a very low seminal volume (0.1 ml). The low testosterone and gonadotropin levels, the remarkable testosterone response to human chorionic gonadotropin (hCG) stimulation, and the sluggish luteinizing hormone (LH) response to luteinizing hormone stimulating hormone (LH-RH) stimulation suggested the presence of hypogonadotropic hypogonadism. Treatment with a combination of human menopausal gonadotropin (hMG)-hCG resulted in the increase in the volume of seminal fluid and the sperm density. His wife achieved two pregnancies during the treatment. This report indicates that the findings of oligospermia and very low seminal volume should be followed by an investigation of the hypothalamo-pituitary testicular axis. Fertility in men with hypogonadotropic hypogonadism can be effectively induced with a combination of hMG-hCG treatment.
