What is the name of the tube that transports sperm from the testis to the prostate gland?

The correct term for the tube that transports sperm from the testis to the prostate gland is the vas deferens. This muscular tube is part of the male reproductive system and plays a key role in the transport of sperm during ejaculation.

The vas deferens connects to the epididymis, where sperm matures and is stored before it moves through the vas deferens to the ejaculatory duct, which then leads to the urethra. The urethra serves a different function, as it is the channel through which both urine and semen are expelled from the body, but it does not transport sperm directly from the testis.

The term "sperm duct" may colloquially refer to the same pathway, but the anatomical term is more precisely the vas deferens. While the seminal duct is not a commonly used term in human anatomy, it can sometimes refer to structures involved in seminal fluid, which is produced by the prostate and seminal vesicles to nourish and transport sperm.

Understanding the distinction between these terms helps clarify the specific roles and pathways within the male reproductive system. Thus, identifying the vas deferens as the key tube for transporting sperm is crucial for grasping human reproductive anatomy.
