Serum and seminal plasma prolactin levels in oligospermia.
Prolactin concentration was estimated by radioimmunoassay in seminal plasma and serum of 26 oligospermic and 23 normospermic men. No significant difference was found in the mean serum prolactin concentration between normospermic and oligospermic subjects, but there was an inverse correlation between serum prolactin level and sperm count within the group of oligospermic patients. Although the mean prolactin concentration in seminal plasma of oligospermic group was somewhat lower than in the normospermic group the difference did not reach statistical significance, and no correlation was found between seminal plasma prolactin concentration and sperm count within either group.
