What is the role of the urethra in the male reproductive system?

The urethra in the male reproductive system serves the important role of transporting both urine and sperm out of the body. This dual function is a key aspect of male anatomy. In males, the urethra runs through the penis, allowing it to carry urine from the bladder as well as semen during ejaculation, which contains sperm.

This structure is specifically designed to manage the excretion of urine and the reproductive process, facilitating the passage of sperm during sexual intercourse. Understanding its function helps to appreciate how the male reproductive and urinary systems are interconnected, providing both the means for waste elimination and reproduction through a single pathway.

Other options presented do not account for this dual capability of the urethra, which is essential for its role in human biology. The urethra does not solely transport urine or sperm, nor does it serve as a storage location for sperm, as sperm is stored in the epididymis and not within the urethra. Thus, option C accurately captures the functional significance of the urethra in the male reproductive system.
