What tube carries sperm from the epididymis to the urethra?

The vas deferens is the tube responsible for transporting sperm from the epididymis to the urethra. This structure plays a crucial role in the male reproductive system as it serves as the pathway through which mature sperm travels during ejaculation. The vas deferens begins at the epididymis, where sperm matures and is stored, and then it moves upward, eventually joining the urethra.

The urethra is primarily a channel for urine but also serves to expel semen during ejaculation. The scrotum, on the other hand, is not a tube but rather a pouch that contains the testicles and regulates their temperature. The seminal vesicle contributes fluids to semen but does not transport sperm itself. Therefore, the vas deferens is the only structure specifically designed for the direct transportation of sperm to the urethra, making it the correct answer.
