Testis has about 250 compartments (Testicular lobules) which contains 1-3 highly coiled seminiferous tubules. Each tubule is lined by 2 types of cells. Male germ cells (immature) (spermatogonic) and Sertoli cells.
Male germ cells form sperms by meiosis and Sertoli cells provide nutrition to these germ cells. Male germ cells and Sertoli cells together form germinal epithelium. Seminiferous tubule is covered outside by basement membrane.
