Cowper's Glands

Cowper's glands, also known as bulbourethral glands, are a pair of small, pea-sized glands in the male reproductive system. Located beneath the prostate gland, these glands play a crucial role in sexual function by producing a clear, slippery fluid that is released into the urethra during sexual arousal and before ejaculation.

The primary function of Cowper's glands is to secrete pre-ejaculate, or pre-cum, which helps to lubricate the urethra and neutralize any acidic urine residue. This process creates a more hospitable environment for sperm to travel through during ejaculation.

Additional Information

Cowper's glands are named after the English anatomist William Cowper, who first described them in detail in the late 17th century. The fluid produced by these glands typically contains no sperm, but in some cases, it may pick up residual sperm in the urethra. This is why the "pull-out" method of contraception is not considered reliable.

The secretions from Cowper's glands make up a small portion of the total volume of semen, with most of the ejaculate coming from the seminal vesicles and prostate gland. However, the pre-ejaculate from these glands plays a vital role in successful sexual intercourse and potential fertilization.
