Definition and Pronunciation
Seminal vesicles (pronounced /ˈsɛm.ɪ.nəl ˈvɛs.ɪ.kəlz/) are a pair of small glands located behind the bladder in males. They produce a significant portion of the fluid that makes up semen, including sugars (fructose) that nourish sperm.
Easy Explanation
Seminal vesicles are two small glands inside the male body that help make semen. They add fluid that feeds sperm and helps them move.
Grammatical Formation
- Part of speech: Noun (plural)
- Singular: Seminal vesicle
- From Latin semen (“seed”) + vesicula (“small bladder or sac”).
Word Comparisons
- Seminal vesicles vs. Prostate gland: Both add fluid to semen, but the seminal vesicles contribute more volume and energy-rich nutrients.
- Seminal vesicles vs. Testicles: Testicles make sperm; seminal vesicles make fluid to carry and protect sperm.
- Seminal vesicles vs. Vas deferens: The vas deferens transports sperm, while seminal vesicles produce seminal fluid.
Connotations
Neutral and medical. The term is rarely used outside of anatomy, fertility, or reproductive health discussions.
Prepositional Usage
- In the seminal vesicles: describes where fluid is stored.
- Blockage of the seminal vesicles: linked to infertility.
- Fluid from the seminal vesicles: makes up the majority of semen.
Real-Life Examples
- About 60–70% of semen volume comes from the seminal vesicles.
- Infections of the seminal vesicles can cause pain and fertility issues.
- The seminal vesicles empty into the ejaculatory ducts during orgasm.
Synonyms
seminal glands, vesicular glands (medical synonyms)
Antonyms
Not direct; female counterpart would be Bartholin’s glands (though functions differ).
Related Terms

Sample Sentences
- The seminal vesicles add fructose to semen, providing energy for sperm.
- A problem with the seminal vesicles can lead to reduced fertility.
- Seminal vesicle fluid mixes with sperm during ejaculation.
Connection to Sexuality
Yes, seminal vesicles are directly tied to sexuality and reproduction. They provide the majority of the fluid that becomes semen, enabling sperm survival and transport during sexual intercourse. Sexual pleasure itself does not come from the seminal vesicles, but their role in ejaculation connects them to male fertility and sexual function. In conversations about masculinity, virility, and reproductive rights, the seminal vesicles are part of the hidden but essential anatomy supporting sexual activity.
