Accessory Sex Glands of Male Animals
Accessory sex glands of male animals are a group of glands associated with the male reproductive system that contribute non-sperm components to the semen.
These glands secrete various fluids that nourish, activate, and transport sperm, as well as facilitate copulation and fertilization.
The secondary andrological organs, which monitor the associated functions for the production of seminal fluid (seminal plasma), are termed andrological accessory glands.
The glandular apparatus consists of the following:
- Seminal vesicle (vesicular gland)
- Prostate gland
- Cowper’s gland
1. Seminal Vesicle (Vesicular Gland)
The seminal vesicles are paired glands located near the bladder. They produce a significant portion of the seminal fluid, which is rich in fructose, providing energy to sperm. This fluid also contains prostaglandins that help with sperm motility and fertilization. Read more about seminal vesicle.
2. Prostate Gland
The prostate gland surrounds the urethra and is responsible for producing a thin, milky fluid that helps nourish sperm and neutralizes the acidity of the urethra. This secretion is vital for sperm activation and mobility. Read more about prostate gland.
3. Cowper’s Gland
Cowper’s gland also known as the bulbourethral glands, Cowper’s glands are located beneath the prostate and secrete a clear, slippery fluid that lubricates the urethra and neutralizes any acidic urine remnants before ejaculation. This fluid also plays a role in facilitating smoother copulation. Read more about Cowper’s gland.
