The hormonal dosage includes systematically testosterone, FSH and LH. These analyses often highlight hypogonadism hypogonadotropic or hypergonadotropic. They can sometimes be normal. The present study aimed to establish the hormonal profile of infertile men residing in Brazzaville. Patients and Methods: It was a cross-sectional descriptive study during five years (from 2018 to 2023). It concerned 344 infertilemen with an abnormal spermogram and spermocytogram. The method was performed from the blood dosage of testosterone, FSH, and LH using the Elisa technique. Results: The hormonal assessment was not normal in 48.83% (168/344) of cases. Increased values of testosterone were noted in 6.10% of cases and decreased in 12.20%. Abnormal high values of FSH were observed in 14.24% of cases and decreased values in 8.13%. LH was elevated, i.e. 2.03% of cases and decreased in 6.10% of subjects. Conclusions: A hormonal disturbance was observed in almost half of the infertile men. It concerned the hypothalamus-pituitary and the testes axis and indicated mainly a state of hypogonadism with high FSH and low LH.展开更多
