Electron-microscopic examination of the human fetal testis between 10 and 20 weeks gestation reveals the presence of two distinct cell types within the tubules: Sertoli cells and germ cells. The latter are distinguished by their spherical shape, smooth nuclear membranes, globular mitochondria and paucity of cytoplasmic organelles. The gonocytes, or primitive germ cells, occur as single cells in the central portions of the tubules. Their chromatin is finely granular and evenly dispersed… CONTINUE READING
