Glossary Seminal Vesicles

glands producing fluid that nourishes and supports sperm

Seminal vesicles, also known as seminal glands, are a pair of glandular structures located behind the bladder in males. They produce a significant portion of the fluid that becomes part of semen, which contains proteins, enzymes, and fructose to nourish and support sperm cells during ejaculation.
