Which structure is responsible for carrying sperm out of the epididymis?

• A. Vas deferens
• B. Seminal vesicle
• C. Urethra
• D. Prostate gland

Answer: (A)

The vas deferens is the structure responsible for transporting sperm from the epididymis, where sperm are stored and matured, to the ejaculatory duct. This muscular tube is essential in the male reproductive system, as it acts as a conduit for sperm to exit the epididymis and move toward the urethra during ejaculation. The other structures mentioned play different roles in reproduction. The seminal vesicle produces fluids that nourish sperm and form a significant part of semen but does not transport sperm. The urethra is the channel through which urine and semen exit the body, but it does not carry sperm from the epididymis specifically. The prostate gland contributes additional fluids to semen but does not serve as a transport pathway for sperm. Therefore, the vas deferens is the key structure for the movement of sperm from the epididymis.
