[Usefulness of examining gonadotropin hormones and testosterone in men with abnormal semen].

The aim of the study was to estimate the usefulness of some hormonal investigations in cases of males with abnormalities in semen analysis in the diagnosis of the male factor in the infertile couple. 107 males with the abnormalities in spermiogram underwent the analysis of the blood serum hormonal levels. Estimated was the level of FSH, LH, prolactin and testosterone. The control group consisted of 31 males with normospermia. The study group was divided according to terminology. In all four groups of infertility the mean values of FSH were significantly higher than in control group. There was no significant differences in LH levels between the groups. The mean values of prolactin level were not significantly higher in the cases of hypospermia than in normospermia group, but significantly higher in the other groups of infertility. The mean level of testosterone was significantly lower in all four groups of infertility in comparison with it's mean level in normospermia group. It was found that the FSH is the most discriminatory hormone in respect of infertility classification and therefore it's diagnostic value is the highest among the four hormones investigated.
