What is the function of the seminal vesicle in the male reproductive system?

The function of the seminal vesicle in the male reproductive system is primarily to produce seminal fluid. This fluid is rich in sugars, proteins, and other substances that contribute to the nourishment and mobility of sperm. It mixes with sperm from the testes to form semen, which is then ejaculated during sexual intercourse. The seminal fluid also helps protect sperm in the acidic environment of the female reproductive tract, providing a more favorable environment for fertilization to occur.

The roles of producing sperm and storing sperm are associated with other structures in the male reproductive system, such as the testes and epididymis, respectively. While the transport of sperm is facilitated by structures like the vas deferens, the specific production of seminal fluid is a unique function of the seminal vesicles.
