Abstract

Serum estrone, estradiol, estriol, progesterone, 17 α-hydroxyprogesterone, and testosterone were determined in the sera of 25 normal males and 25 patients with obstructive azoospermia. An increase in testosterone and estriol levels, and a decrease in other hormones were demonstrated in patients with obstructive azoospermia. These long-term effects of obstruction of the vas apparently also occur in comparable situations, for example, after vasectomy.
