Endocrine Studies of Azoospermia. I. Serum Steroid Levels in Sertoli Cell Only Syndrome

Abstract
Estrone, estradiol, estriol, progesterone, 17α-hydroxyprogesterone, testosterone, and dihydro-testosterone levels were determined in sera of 20 fertile men and 15 male patients with Sertoli cell only syndrome. In men with Sertoli cell only syndrome there was a significant decrease in serum estrone, estradiol, progesterone, 17α-hydroxyprogesterone, and dihydrotestosterone and a significant increase in serum estriol and testosterone. Changes in endocrine profile discussed in relation to the possible role of inhibin.
