title: 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.
abstract: 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.
