Testes formation[ edit ] During mammalian development, the gonads are at first capable of becoming either ovaries or testes. At about week 6, epithelial sex cords develop within the forming testes and incorporate the germ cells as they migrate into the gonads. In males, certain Y chromosome genes, particularly SRY , control development of the male phenotype, including conversion of the early bipotential gonad into testes.

In males, the sex cords fully invade the developing gonads. Androgen production[ edit ] The mesoderm-derived epithelial cells of the sex cords in developing testes become the Sertoli cells, which will function to support sperm cell formation. real dick toy
