[Pathomorphological studies of the testes in various forms of hypogonadism in young men].

The authors studied 32 biopsies of testes of patients, aged 18 to 26 with various forms of male hypogonadism: Klinefelter's syndrome--16, primary hypotrophy pogonadism with other known and unknown etiology--6, cryptorchism--1, secondary hypogonadism--4, later puberty--3. The materials were studied by the standard histological techniques. The authors report about definite structural changes with the various forms of hypogonadism, manifested in the elements of seminal tubules, Sertoli's cells, basal membrane of the ducts and Leydig's cells, situated in the interstitial spaces.
