| Abstract: | Summary The ultrastructural study of testicular biopsies from 87 adult men revealed mitosis in two mature Leydig cells, each from a different man. The men showed normal hormone levels and had received no previous chemotherapy or hormone treatment, nor had they been exposed to known toxic agents. The presence of mitotic Leydig cells suggests that differentiated Leydig cells may divide and contribute either to the increase in the number of Leydig cells or to the formation of multinucleate Leydig cells.This work was partially supported by a grant from the  Comisión Asesora de Investigación Científica y Técnica , Madrid, Spain |
