The testes are ovoid organs that produce sperm (spermatogenesis).

Tunica Albuginea is a thick connective tissue capsule. Lobules are pyramid-shaped lobules that are separated by connective tissue septae that extend inward from the capsule.

Each seminiferous tubule contains 1 to 4 highly coiled seminiferous tubules lined by sperm-producing germinal epithelium.

Sertoli Cells are large, columnar cells that extend throughout the germinal epithelium.
