Which gland produces seminal fluid that nourishes and activates sperm?

The seminal vesicle plays a crucial role in human reproduction by producing seminal fluid, which nourishes and activates sperm. These glands are responsible for secreting a significant portion of the fluid that makes up semen. The fluid produced by the seminal vesicles contains nutrients like fructose, which provides energy for sperm, as well as other substances that aid in the mobility and viability of sperm cells once they are ejaculated.

In the context of reproduction, this nourishment is essential because sperm must travel through the female reproductive tract to reach the egg for fertilization. The functioning of the seminal vesicles ultimately enhances the chances of successful fertilization by providing an optimal environment for the sperm.

The other glands listed also contribute to the production of semen but serve different roles or provide different components. The prostate gland adds a slightly alkaline fluid to the semen, which helps to neutralize the acidic environment of the vagina. The bulbourethral glands secrete a small amount of pre-ejaculate fluid that lubricates the urethra and may help neutralize acidity. The testis is primarily responsible for the production of sperm and testosterone but does not produce seminal fluid. The seminal vesicle’s specific function in producing seminal fluid that nourishes and activates sperm makes it the correct answer
