Epididymis

Epididymis is a tube located at the back of the testicles that stores and carries sperm. It is a part of the male reproductive system and is essential for the maturation of sperm, which are produced in the testicles. The epididymis transports sperm from the testicles to the vas deferens, another tube that carries the sperm to the urethra for ejaculation.

Structure

The epididymis is a long, coiled tube that is divided into three sections: the head, body, and tail. The head receives sperm from the testicle via the efferent ductules. The body is the middle portion, and the tail connects to the vas deferens.

Function

The primary function of the epididymis is the storage, maturation, and transport of sperm. Sperm that are produced in the testicles are immature and lack the ability to swim forward or fertilize an egg. It is in the epididymis that sperm gain these abilities.

Clinical significance

Problems with the epididymis can lead to male infertility. Inflammation of the epididymis, known as epididymitis, is a common condition that can cause pain and swelling in the testicles. Other conditions that can affect the epididymis include epididymal cysts and epididymal obstruction, which can block the passage of sperm.
