What are the epididymis?

The epididymis is a long, coiled tube that connects the testes to the vas deferens. It is located on the back of each testicle. The epididymis is responsible for storing sperm and helping them to mature.

Sperm are produced in the seminiferous tubules of the testes. They are then transported to the epididymis, where they are stored for up to several months. During this time, the sperm mature and become capable of fertilizing an egg.

The epididymis is also responsible for reabsorbing water and other fluids from the sperm. This helps to concentrate the sperm and make them more motile.

The epididymis is lined with cilia, which are small, hair-like structures. These cilia help to move the sperm through the epididymis.

The epididymis is an important part of the male reproductive system. It is responsible for storing sperm and helping them to mature. Without the epididymis, sperm would not be able to fertilize an egg.
