Light microscopy of a fetal testis. The characteristic features are the solid, coiled seminiferous cords that in postnatal life will become seminiferous tubules, and clusters of Leydig cells (red) between the cords. The cords contain Sertoli cells and germ cells termed spermatogonia (round cells). The spermatogonia will become the stem cells for subsequent sperm development during spermatogenesis. Blood vessels some large, are located just deep to the testis capsule. Magnification x80 when printed at 10 cm wide.
