[noun]

Seminal vesicle

[NOUN]

a paired gland in the male reproductive system that secretes fluids to nourish and support the sperm cells

What is "seminal vesicle"?

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.

Examples

1. At this point, the contractions carry the mature sperm from the epididymis through two muscular ducts called the vas deferens, which carry them up from the testes, up and over the bladder, and down past the seminal vesicles.

2. One set can develop into the uterus and fallopian tubes, while the other set has the potential to become the epididymis, vas deferens, and seminal vesicles.

3. The seminal vesicles are a pair of small, hollow glands behind the bladder that secrete a yellowish, slightly alkaline fluid that contains coagulating enzymes, fructose, and other things to help nourish and transport sperm.
