title: Fine structure of Sertoli and Leydig cells in azoospermic human testis.
abstract: Testicular biopsy specimens taken from seven patients with azoospermia were studied by electron microscopy. We considered the possibility of a relationship between the annulate lamellae in the Sertoli cells and azoospermia. In the Leydig cells, we observed intranuclear and intracytoplasmic paracrystalline inclusions and considered their relationship with the Reinke crystalloid.
