What structure serves as the exit point for urine and semen in males?

The urethra functions as the exit point for both urine and semen in males. It is a tube that runs through the penis and opens to the outside of the body, allowing for the expulsion of these fluids. The dual function of the urethra—which is involved in both the urinary and reproductive systems—plays a critical role in male physiology.

The vas deferens is primarily responsible for transporting sperm from the testes to the urethra but does not serve as the exit point itself. The penis is the external organ that facilitates the expulsion of urine and semen, but it is the urethra within that organ that actually conducts these fluids outside the body. The prostate gland contributes to the production of seminal fluid but is not the structure through which urine or semen exits. Therefore, the urethra is the correct answer due to its essential role in the male reproductive and urinary systems.
