Final answer:
The urethra is the part of the genitourinary system that also transports sperm in males. It serves dual functions of urine excretion and semen ejaculation. The urinary bladder is only involved in the urinary system and the vas deferens transports sperm but has no role in urine passage.
Step-by-step explanation:
The part of the genitourinary system that also transports sperm is the urethra. In males, the urethra is used for the excretion of urine as well as the ejaculation of semen which contains sperm. This differs from females, where the urethra is only involved in the excretion of urine. The structure that is only related to the male urinary system and not the reproductive system is the urinary bladder. Conversely, the vas deferens is responsible for carrying sperm from the testes towards the, but it is not involved in the passage of urine.
The statements about the male reproductive system that are false include: the prostate gland is located in the testes, and the vas deferens carries from the testes to the seminal vesicles. The vas deferens actually carries sperm from the testes towards the ejaculatory ducts, which then join the urethra.
