What is the primary function of the male reproductive system?

The primary function of the male reproductive system is to produce sperm and deliver it to the female reproductive system. This encompasses several critical processes, including the production of spermatozoa within the testes through spermatogenesis, as well as the maturation and transport of sperm through the male reproductive tract.

The male reproductive system is specifically designed for this purpose, featuring structures such as the epididymis for storing and maturing sperm, and the vas deferens for transporting sperm during ejaculation. Additionally, the seminal vesicles and prostate gland contribute fluids that nourish and protect sperm, facilitating successful delivery into the female reproductive tract during reproduction.

Focusing on the other options: while hormone production is indeed a function of the male reproductive system, particularly testosterone, it is secondary to the main role of sperm production and delivery. Similarly, urine storage and transport are managed by structures like the bladder and urethra, which are part of the urinary system, not specific to the reproductive system. The exchange of genetic material occurs during fertilization when sperm penetrates an egg, but this is a result of the primary function of the reproductive system rather than its core purpose.
