Primate spermatogenesis: New insights into comparative testicular organization, spermatogenic efficiency and endocrine control

Article Abstract:

New data and insights into comparative primate spermatogenesis, dealing specifically with quantitative aspects of germinal epithilial organization and germ cell production and with roles of gonadotrophic hormones in this process is presented. Key spermatogenic features are preserved across all primate taxa whereas male reproductive endocrinology features appear substantially different in the neotropical primates compared to other primate lineages.
