The structure of the male reproductive system that carries sperm from the epididymis to the ejaculatory duct is indeed the vas deferens. The vas deferens is a muscular tube that plays a crucial role in the reproductive process by transporting mature sperm during ejaculation.

As sperm mature in the epididymis, they are stored there until they are ready to be delivered. When ejaculation occurs, the sperm move into the vas deferens, which contracts to propel the sperm forward. This pathway is essential for the normal function of the male reproductive system, ensuring that sperm is efficiently transported and mixed with seminal fluid before being expelled from the body.

The prostate gland, while important for producing fluids that nourish and protect sperm, does not transport sperm itself. Instead, it plays a supportive role in the reproductive process. The ejaculatory duct is the passage that sperm enters after traveling through the vas deferens, but it does not carry sperm directly from the epididymis. The seminal vesicle produces fluid that contributes to the composition of semen, but again, it is not responsible for carrying sperm. Thus, the vas deferens is the correct answer for this question regarding the transport of sperm following maturation in the epididymis.
