Mammalian spermatogenesis occurs in the convoluted seminiferous tubules of the testes, where spermatogenic stem cells （SSCs） reside on sustentacular Sertoli cells of somatic origin, forming a germinal epithelial structure. Spermato genesis is accomplished in a complicated, timely controlled differentiation of SSCs into premeiotic primary spermatocytes, followed by formation of postmeiotic round spermatids and their subsequent maturation into spermatozoa.展开更多
