Learn something new every day More Info Together with the prostate and seminal vesicles, these glands make a mucus -like substance that goes into semen and also acts as a lubricant during sex. They also makes pre-ejaculate fluid, which is the primary lubricant secreted by men during sex and also helps with fertilization and keeps the urethra clear of debris. The amount of fluid secreted varies depending on how old a man is, how long it's been since he ejaculated, and how aroused he is. It's slightly alkaline, so it neutralizes acid levels in a man's urethra so that his sperm can move freely. It also flushes the urethra of debris like pathogens.

What is a Cowper's Gland? (with pictures)

Pre-cum, otherwise known as pre-ejaculatory fluid, is a clear, sticky fluid secreted by the penis during sexual arousal. Pre-cum is capable of transmitting sexually transmitted infections STIs like human immunodeficiency virus HIV from an infected individual to their partner, so it is recommended to use a form of protection like a male or female condom during sex to avoid any significant risk. These small glands are also known as the bulbourethral glands. This pair of organs is located just below the prostate gland and are parallel to the urethra , the primary channel which transports urine and semen out through the penis. This process of secreting pre-ejaculatory fluid most often occurs during the plateau phase of the male sexual response cycle. This fluid contributes to the overall sexual response by neutralizing the urethra, in turn creating a pH balanced environment in which sperm can survive before ejaculation.

Pre-ejaculate

Pre-ejaculate also known as pre-ejaculatory fluid , pre-seminal fluid or Cowper's fluid , and colloquially as pre-cum is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal. It is similar in composition to semen but has distinct chemical differences. The presence of sperm in the fluid is variable from low to absent. Pre-ejaculate functions as a lubricant and an acid neutralizer. The fluid is discharged from the urethra of the penis during arousal , masturbation , foreplay or at an early stage during sexual intercourse , some time before the individual fully reaches orgasm and semen is ejaculated.

The bulbourethral gland or Cowper's gland named for English anatomist William Cowper is one of two small exocrine glands in the reproductive system of many male mammals of all domesticated animals, they are absent only in dogs. The bulbouretheral glands are responsible for producing a pre-ejaculate fluid called Cowper's Fluid colloquially, pre-cum , which is secreted during sexual arousal, neutralizing the acidity of the urethra in preparation for the passage of sperm cells. Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis, between the two layers of the fascia of the urogenital diaphragm , in the deep perineal pouch. They are enclosed by transverse fibers of the sphincter urethrae membranaceae muscle. The bulbourethral glands are compound tubulo-alveolar glands , each approximately the size of a pea in humans.
