WebJun 30, 2024 · The sperm move from the testes, through the epididymis, and into the vas deferens prior to being mixed with various secretions at the time of ejaculation. During their time moving through the epididymis, sperm mature and gain additional function. In particular, they gain the ability to propel themselves forward. WebSperm leave the testes through a series of efferent ducts that enter the epididymis. Each epididymis is a long (about 6 meters) tube that is tightly coiled to form a comma-shaped organ located along the superior and posterior margins of the testes.
