Quantitative Analysis of Spermatogenesis and Apoptosis in the Common Marmoset (Callithrix jacchus) Reveals High Rates of Spermatogonial Turnover and High Spermatogenic Efficiency1

Abstract excerpt

Spermatogenesis is characterized by the succession in time and space of specific germ cell associations (stages). There can be a single stage (e.g., rodents and some macaques) or more than one stage (e.g., chimpanzee and human) per tubular cross section. We analyzed the organization of the seminiferous epithelium and quantified testicular germ cell production and apoptosis in a New World primate, the common...
