HISTOLOGIA TESTICULAR HUMANA COMPARADA, ADULTO JOVEN Y SENIL

In general, sperm production decreases with advanced age in men. Therefore the present work compares the histology and cellularity of aging human testis with that of a young adult. Gonads from three patients 69 years old and testis from a young subject (aged 25 years) were examined after histologic...
