What is the primary function of the vesicular glands?

The primary function of the vesicular glands, also known as seminal vesicles, is to provide nutrients and buffering to the seminal fluid. These glands produce a significant portion of the fluid that makes up semen, which contains sugars such as fructose that serve as energy sources for sperm. Additionally, the fluid produced by the vesicular glands has a higher pH to help neutralize the acidity of the female reproductive tract, creating a more favorable environment for sperm survival.

The nutrients supplied by the vesicular glands play a crucial role in enhancing sperm motility and viability, which is essential for successful fertilization. This aspect of the reproductive system supports the overall goal of reproduction by ensuring that sperm can effectively reach and fertilize the egg.

Other functions mentioned, such as producing hormones, cleansing the urethra, or forcing semen from the urethra, are not the primary roles of the vesicular glands, making their contributions in nutrient provision and buffering vital to the reproductive process.
