Function of the Seminal Vesicles:

* Produce seminal fluid: The seminal vesicles contribute about 60% of the volume of semen. This fluid is rich in:

* Fructose: A sugar that provides energy for sperm.

* Prostaglandins: Hormones that help with sperm motility and cervical mucus thinning.

* Citric acid: An antioxidant that protects sperm.

* Other proteins and enzymes: These support sperm function and survival.

* Contribute to semen volume and viscosity: The seminal vesicles help to provide the volume and consistency of semen, making it suitable for transporting sperm.

* Neutralize acidity: Semen is slightly alkaline, helping to neutralize the acidity of the vaginal environment, which is important for sperm survival.

In summary, the seminal vesicles play a crucial role in:

* Providing nutrients and support for sperm.

* Ensuring the correct environment for sperm transport and survival.

* Contributing to the volume and consistency of semen.

It's important to note that the prostate gland and bulbourethral glands are also involved in semen production, each contributing unique components that support sperm function.
