Correlation between follicle-stimulating hormone, luteinizing hormone, prolactin, and testosterone with sperm cell concentration and motility.
Follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), and testosterone were measured by radioimmunoassay in blood and seminal plasma of normo-spermic and oligospermic men. These parameters were correlated with sperm cell concentration as well as sperm motility. Average motility in the oligospermic group was significantly decreased as compared with the normospermic group (P less than .001). A significant reciprocal correlation was demonstrated between blood LH concentrations and sperm cell concentrations (P less than .05) as well as sperm motility (P less than .02). In contrast, a significant positive correlation was demonstrated between seminal LH concentrations and sperm cell count and motility (P less than .001). Seminal FSH and testosterone concentrations were positively correlated with sperm output but not sperm motility (P less than .05). The increased concentrations of LH in circulation accompanying idiopathic oligospermia suggests that LH secretion may be linked to the factors regulating spermatogenesis. The significant correlation between seminal testosterone and sperm concentration demonstrated in this study offers further support to this hypothesis. The significance of the correlation between the levels of LH and FSH in seminal plasma and sperm cell concentration and sperm motility is unknown.
