The seminal vesicle, associated with the male reproductive system, contributes to semen production by secreting fluids that provide nourishment and mobility to sperm cells. The seminal vesicles primarily produce fructose, prostaglandins, and other substances that support sperm function. Hormonal regulation of the seminal vesicles occurs indirectly through the hypothalamic-pituitary-gonadal axis, which influences testosterone production in the testes. However, the seminal vesicles themselves do not produce hormones or play a direct role in the endocrine system.
