Effect of synthetic LH-RH and hCG administration on plasma testosterone, androstenedione, and estradiol 17beta levels in normal men and in patients with idiopathic oligospermia.
Plasma testosterone, androstenedione, and estradiol 17beta levels were measured in 20 normal men and in 20 patients with idiopathic oligospermia before and after iv hCG (5,000 IU) and synthetic LH-RH (50 microgram) administration. No statistically significant differences in the concentrations of the steroids examined were detected between patients and controls either under control conditions or under exogenous and endogenous gonadotropin stimulation.
