Vas deferens

August 2017


Definition

The vas deferens is a channel in the male reproductive tract, which begins in the testicles and brings spermatozoa to the prostate. It is also called the sperm duct. It connects to the ejaculatory duct. The vas deferens is composed of contracting muscles that make the spermatozoa flow. In the case of a vasectomy, the vas deferens is blocked. However, spermatozoa are still produced by the testicles.
