WebFeb 9, 2024 · Germinal epithelium is a thick layer of cells that covers the sex organs during the early developmental stage of the embryo. These are cuboidal cells found in both testes and ovary. In males, it covers the wall of seminiferous tubules within testes. In females, it covers the outermost layer of the ovary. The germinal epithelium is the epithelial layer of the seminiferous tubules of the testicles. It is also known as the wall of the seminiferous tubules.
