Which duct transports sperm from the testicle toward the urethra?

• A. Ureter
• B. Urethra
• C. Vas deferens
• D. Bladder

Answer: (C)

Sperm move from the testicle toward the urethra through the vas deferens, a muscular duct that carries sperm from the epididymis in peristaltic waves toward the ejaculatory ducts and then the urethra. After maturation in the epididymis, sperm are propelled along this duct as part of the semen’s journey to exit the body. The ureter transports urine from the kidney to the bladder, and the bladder stores urine. The urethra is the final conduit for urine and semen to leave the body, but the tube that actively transports sperm away from the testicle is the vas deferens.
