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

• A. Produces testosterone
• B. Stores sperm
• C. Produces seminal fluid for sperm cells
• D. Regulates sperm transport

Answer: (C)

The seminal vesicle plays a crucial role in the male reproductive system by producing seminal fluid, which is a key component of semen. This fluid provides a nourishing medium for sperm cells and helps facilitate their mobility. By adding volume and nutrients, such as fructose, to the semen, the seminal vesicle enhances the chances of successful fertilization. Seminal fluid also contributes to the viscosity and alkalinity of the semen, creating a more favorable environment for sperm survival once inside the female reproductive tract.

Other choices reflect different functions associated with the male reproductive system. For instance, testosterone production is the primary function of the testes, while sperm storage occurs in the epididymis. Sperm transport regulation is mainly managed by the vas deferens and other associated structures. Therefore, the function of the seminal vesicle is specifically linked to the production of seminal fluid, making this choice the most accurate.
