Abstract
It is commonly accepted that aging drastically affects the male reproductive power, disturbing and preventing hormonal secretions, germinal cell proliferation and ejaculation (1,2, 3,4,5). Fine structural studies have been carried out on Leydig cells both in humans (6,7) and Stallions (8), all of them mainly dealing with functional parameters, and on human Sertoli cells (9). Leydig cells appear increased both in number and in volume, in ageing stallions, decreased in humans concomitantly with a declining androgen status. Sertoli cells resume a high capacity to divide, and frequently give rise to binucleate cells. No informations are available concerning spermatozoa and spermatogenesis.
