Abstract

Testicular biopsy specimens taken from 7 patients, 31 to 41 yr old, with azoospermia were studied by electon microscopy. The patients displayed well-developed secondary sex characteristics, normal endocrine functions (determined by circulating and urinary gonadotropin levels), and normal plasma testosterone and T4 levels. It was clear that the infertility was directly related to a primary testicular defect. The possibility was considered of a relation between the annulate lamellae in the Sertoli cells and the azoospermia. In the Leydig cells, intranuclear and intracytoplasmic paracrystalline inclusions were observed and a relation with the Reinke crystalloids is considered.
