摘要

Spermatogenesis is a dynamic, finely hormonally regulated, and strictly spatially organized process by which spermatogo-nia divide, develop, and differentiate into spermatozoa. Spermatogenesis relies on two apparently opposite processes: the maintenance of the integrity of the seminiferous epithelium and the movement of germ cells from its base to its apex. Maintenance of the architectural integrity that is fundamental for spermatogenesis is, ensured by three checkpoints: the seminiferous tubule basement membrane; the inter-Sertoli cell blood-testis barrier (BTB), sometimes more accurately referred to as the blood-seminiferous tubule barrier; and ectoplasmic specializations (ES) between Sertoli and differentiating germ cells. The BTB divides the seminiferous epithelium into two compartments: the basal compartment, which forms the niche for spermatogonial proliferation and renewal and the initiation of meiosis, and the adlumenal compartment, where meiosis is completed and spermiogenesis occurs.
