Final answer:
The urethra is the part of the male urogenital tract that is utilized by both the urinary and reproductive systems. It facilitates the passage of urine and serves as the conduit for semen during ejaculation.
Step-by-step explanation:
The part of the male urogenital tract that is shared by the urinary and reproductive systems is the urethra. The urethra serves a dual function in males; it carries urine from the bladder to the outside of the body and also transports semen during ejaculation. The other options listed, such as the vas deferens, prostate gland, and epididymis, are specifically associated with the reproductive system and not the urinary tract. The vas deferens transports sperm from the testes towards the urethra, the prostate gland produces a fluid that is a component of semen, and the epididymis is where sperm mature after being produced in the seminiferous tubules.
Additionally, it is important to note that one of the false statements provided is that the prostate gland is located in the testes, when in fact, it is situated below the bladder surrounding the urethra.
