Testicular

Testicular refers to anything related to the testes, the male reproductive glands. The testes are responsible for producing sperm and the male hormone, testosterone. They are located in the scrotum, a pouch of skin that hangs behind the penis.

Anatomy

The testes are oval-shaped and about the size of large olives. They are made up of a series of coiled tubes called seminiferous tubules, which are responsible for producing sperm. The tubules are surrounded by other cells that produce testosterone.

Function

The primary functions of the testes are to produce sperm and to produce hormones, particularly testosterone. Testosterone is responsible for the development of male secondary sexual characteristics, such as increased muscle mass, body hair, and a deep voice.

Health Issues

There are several health issues that can affect the testes, including testicular cancer, testicular torsion, and varicocele. Testicular cancer is a relatively rare form of cancer, but it is the most common cancer in men aged 15-35. Testicular torsion is a medical emergency that occurs when the spermatic cord, which provides blood flow to the testicle, twists and cuts off the blood supply. Varicocele is a condition characterized by enlarged veins in the scrotum, similar to varicose veins.
