The structure of the male anatomy that carries sperm out of the epididymis is called the vas deferens (also known as the ductus deferens).

Here's a breakdown:

* Epididymis: This is a coiled tube located on the back of each testicle where sperm mature and are stored.

* Vas Deferens: This is a long, muscular tube that carries mature sperm from the epididymis to the ejaculatory duct, which then joins with the urethra.
