Which duct transports sperm from the testis toward the prostatic urethra?

• A. Vas Deferens
• B. Epididymis
• C. Urethra
• D. Seminal Vesicle

Answer: (A)

The main idea is the path sperm take as it moves toward ejaculation. The duct responsible for carrying sperm from the epididymis toward the prostatic urethra is the vas deferens (ductus deferens). It is a muscular tube that transports sperm from the epididymis up into the pelvis, where it joins with the duct from the seminal vesicle to form the ejaculatory duct, which then empties into the prostatic urethra. The epididymis primarily functions as the site where sperm mature and gain motility, storing them before they move into the vas deferens. The urethra is the final passageway for semen and urine, not the conduit that carries sperm from the testis toward the prostate. The seminal vesicles contribute fluid to semen but do not transport sperm themselves.
