What are the functions of prostate gland and seminal vesicle?

The prostate gland and seminal vesicles are key components of the male reproductive system. Their functions are as follows:

Prostate Gland:

• Secretion of Prostate Fluid: The prostate gland produces a slightly alkaline fluid that forms part of the semen. This fluid helps to neutralize the acidic environment of the vagina, providing a better environment for sperm to survive and swim.
• Enhancing Sperm Motility: The fluid produced by the prostate contains enzymes that aid in sperm motility, enhancing the chances of fertilization.
• Regulation of Semen: The prostate also helps in the regulation of semen, adding volume and providing a medium for sperm to move through the reproductive tract.
• Hormonal Function: It produces substances like prostate-specific antigen (PSA), which play a role in sperm liquefaction, allowing sperm to swim more freely after ejaculation.

Seminal Vesicles:

• Production of Seminal Fluid: The seminal vesicles produce a significant portion of the seminal fluid, which is rich in fructose. This provides energy for the sperm, helping them to move efficiently.
• Nutrient Supply for Sperm: The fluid produced by the seminal vesicles contains proteins, enzymes, and prostaglandins, which nourish sperm and support their motility.
• Formation of Semen: The seminal fluid from the seminal vesicles mixes with sperm from the testes and fluids from the prostate gland, forming semen during ejaculation.
