Serum prolactin concentration in impotent African males.

abstract：:In 17 cases of male sterility with so-called "mixed atrophy" in testicular biopsies, the germinal epithelium was investigated by quantitative as well as by ultrastructural means. In 13 cases, the number of spermatids only was reduced, in 2 cases earlier stages of germinal cells were diminished also. Normal quantitativ...
