Final answer:
The shared structure between the male urinary and genital systems is the urethra, which carries both urine and semen during different bodily functions. Option A is correct.
Step-by-step explanation:
The structure shared by the male urinary and genital system is the urethra. The male urethra functions in the transport of urine from the urinary bladder to the outside of the body, and during ejaculation, it serves as a conduit for semen, which contains sperm from the ejaculatory ducts, along with secretions from the prostate gland and other accessory sex glands like the Cowper's gland or bulbourethral gland.
In contrast, the prostate, corpus, and ureter do not have a dual role and are not shared directly between the urinary and reproductive systems.
To clarify, the prostate is part of the male reproductive system but does not carry urine, whereas the ureter is only involved in the transport of urine from the kidneys to the bladder and the corpus is involved in erection.
The structure shared by the male urinary and genital system is the urethra.
The male urethra passes through the prostate gland and carries both urine from the bladder and semen from the ejaculatory ducts through the .
This shared structure allows for the elimination of urine and the passage of sperm during sexual intercourse.
