What is produced by the seminal vesicle?

The seminal vesicle plays a crucial role in the male reproductive system, primarily producing a significant component of semen. This gland is responsible for secreting a fluid that is rich in fructose, which provides energy for sperm and aids in their motility. The fluids produced by the seminal vesicles make up a substantial portion of the total volume of semen, which is vital for the successful transportation and nourishment of sperm during ejaculation.

Semen itself is a mixture of sperm and various fluids produced by several glands, including the seminal vesicles, prostate, and bulbourethral glands. These fluids serve not only to facilitate the sperm's mobility but also to create a suitable environment for fertilization to occur when sperm meet an ovum. Therefore, the contribution of seminal vesicles is critical to reproductive success.
