What is the primary function of the prostate gland?

The primary function of the prostate gland is to produce seminal fluid, which is a key component of semen. This fluid plays a critical role in the reproductive process, as it nourishes sperm and facilitates their movement during ejaculation. The prostate contributes to the fluid that makes up about 30% of semen, combining with sperm from the testes and other fluids from the seminal vesicles to create a medium that supports sperm during their journey through the female reproductive tract.

Understanding this function highlights the importance of the prostate in male fertility and reproductive health. By producing seminal fluid, the prostate gland ensures that sperm can survive longer and travel more efficiently, increasing the chances of successful fertilization. This is why the choice indicating the production of seminal fluid accurately reflects the primary role of the prostate gland in the male reproductive system.
