title: Serum levels of gonadotropins, prolactin, and testosterone in oligo/azoospermic Nigerian males.
abstract: To determine the frequency of hormonal abnormalities in a Nigerian population of male partners of infertile relationships, serum levels of luteinizing hormone, follicle-stimulating hormone, prolactin, and testosterone were estimated using radioimmunoassay techniques in 454 oligo/azoospermic male partners of infertile marriages. Of these men, 272 (59.9%) had an abnormal serum level of one or more of the hormones. Hyperprolactinemia, found in 144 patients, was the most common hormonal disorder in the group. Elevated serum gonadotropins associated with low serum testosterone were found in 120 (26.4%) patients, while 32 (7%) had a reduced serum testosterone concentration in association with low serum gonadotropins. Since hyperprolactinemic, hypogonadotropic, and normogonadotropic testicular failures are amenable to treatment, routine hormonal evaluation of male partners of infertile marriages is suggested in Nigeria and other places where this practice is uncommon at present.
