Testis (2) Diagram

The testes are covered by outer fibrous tunica vaginalis, middle tunica albuginea, and inner tunica vasculosa. Internally, the testes are divided into about 250-300 pyramid-shaped compartments called testicular lobules.
On the testis, we can observe two sides (medial and lateral) that are separated by two edges (anterior and posterior). We can also observe superior and inferior poles since it is an ovoid organ.
The testes have two primary functions. The first function of the testes is to produce testosterone. Testosterone is a steroid hormone that is responsible for sexual differentiation of the male. It is important for prenatal development.
