Epididymis

Definition

The epididymis is a coiled tube located at the back of the testicle that stores and carries sperm. It plays a crucial role in the maturation and transport of sperm cells.

5 Must Know Facts For Your Next Test

1. The epididymis is divided into three parts: the head, body, and tail.
2. Sperm mature as they pass through the epididymis, gaining motility and fertilization capability.
3. Infections in the epididymis are known as epididymitis and can cause pain and swelling.
4. The normal microbiota of the urogenital tract can affect the health of the epididymis.
5. The epididymis connects to the vas deferens, which transports mature sperm to the urethra during ejaculation.
