Fluid produced by the male on ejaculation.
It is composed of fluid from the seminal vesicles, fluid from the prostate and Cowper’s glands, and sperm.
Fluid produced by the male on ejaculation from the penis at sexual orgasm. Each ejaculate contains up to 500 million spermatozoa (male germ cells) suspended in a ?uid that is secreted by the PROSTATE GLAND, seminal vesicles (see TESTICLE), and Cowper’s glands – a pair of small glands (also called the bulbo-urethral glands) that open into the URETHRA at the base of the penis. Semen, or seminal ?uid, contains a form of sugar (fructose) essential for the motility of sperm. The hormone TESTOSTERONE is a key element in the production of sperm and of seminal ?uid.
(seminal fluid) n. the fluid ejaculated from the penis at sexual climax. Each ejaculate may contain 300–500 million spermatozoa suspended in a fluid secreted by the *prostate gland and *seminal vesicles with a small contribution from *Cowper’s glands. It contains fructose, which provides the spermatozoa with energy, and *prostaglandins, which affect the muscles of the uterus and may therefore assist transport of the spermatozoa. —seminal adj.
