[Male fertility in the elderly].
Fertility in the elderly is still a less known argument. We report some news about seminal parameters (SP) and testicular hystological parameters (THP) in this age. About SP: the volume of the ejaculate, the number and the motility of spermatozoa are reduced. The morphology is typical: spermatozoa with coiled tails are common. About THP: some testes show a normal hystological architecture; others show a reduced volume and some aspects of hypospermatogenesis or maturative arrest; others show a very reduced volume, thickness of the tubular basal membrane and other signs of cellular regression. These signs are dependent upon the vascular insufficiency and the hormonal alterations which may occur in the elderly.
