Which parts make up the male reproductive system?

The male reproductive system is primarily comprised of the testes, scrotum, and penis. The testes are responsible for producing sperm and hormones, particularly testosterone. The scrotum holds and regulates the temperature of the testes, which is crucial for optimal sperm production. Lastly, the penis serves as the organ for delivering sperm to the female reproductive system and is involved in urination. This understanding of the male reproductive anatomy is crucial for EMDs, as it enables them to recognize specific medical emergencies and provide appropriate pre-arrival instructions.

The other options contain components that are associated with the female reproductive system or mix male and female reproductive parts incorrectly, highlighting their inapplicability to the question at hand. For instance, ovaries and fallopian tubes are exclusive to the female reproductive tract, and the presence of the uterus and vagina indicates a focus on female anatomy.
