Which duct carries sperm from the testicle toward the urethra?

• A. Epididymis
• B. Urethra
• C. Seminal vesicle
• D. Vas deferens

Answer: (D)

Sperm travel from the testicles through a series of ducts, undergoing maturation in the epididymis, where they are stored and gain motility. From there, they move into the vas deferens, a muscular tube that propels sperm toward the urethra mainly through peristaltic contractions during ejaculation. This transport role makes the vas deferens the duct that carries sperm toward the urethra. The urethra is the final pathway for semen to exit, but it’s the vas deferens that provides the main conduit from the testis toward that destination. The epididymis is important for maturation and storage, but its role is not the primary transport toward the urethra, and the seminal vesicles are glands that add fluid rather than serve as the main transport duct.
