What is the primary function of the prostate gland?

The primary function of the prostate gland is to produce seminal fluid, which plays a crucial role in male reproduction. This fluid makes up a significant portion of the semen, providing a medium for sperm to swim and enhancing sperm viability. The prostate gland secretes this fluid during ejaculation, which is vital for the transportation of sperm from the male reproductive system to the female reproductive system.

The production of seminal fluid by the prostate not only nourishes the sperm but also helps to protect them from the acidic environment of the female vagina, thereby increasing the chances of successful fertilization. Understanding the prostate's role in seminal fluid production is fundamental to grasping male reproductive health.
