This long muscular tube runs from the epididymis into the pelvic cavity behind your bladder and connects to your urethra through a structure called the ejaculatory duct. Your vas deferens is surrounded by your spermatic cord and transports mature sperm to the urethra before you ejaculate.
Your testes are the place where sperm cells are created. From there, the sperm moves into the epididymis, which is a structure located on top of the testicle. The epididymis stores sperm cells and has the job of bringing them to maturity so they’re able to fertilize eggs.
When you’re sexually aroused, muscle contractions move the sperm from the epididymis to the vas deferens and from there into the urethra so you’re able to ejaculate semen outside of your body. During the process, your body adds secretions to the sperm cells to make semen.
