The bulbourethral glands are a part of the male reproductive system. They could even be known as the Cowper’s glands since they had been first documented by anatomist William Cowper within the late 1600s.
The paired bulbourethral glands are roughly the dimensions of a pea and are positioned within the deep perineal pouch. They’re on the base of the penis and are lateral (to the aspect) and posterior to (behind) the urethra, which is the tube via which semen and urine exit the physique.
They’re exocrine glands with roughly 2.5 cm ducts that cross via the perineal membrane and into the close by portion of the spongy urethra. When sexually aroused, the glands produce a mucous-like fluid known as pre-ejaculate. The pre-ejaculate fluid is a viscous, clear, and salty liquid that neutralizes any residual acidity within the urethra. The now neutralized urethra is a extra hospitable (versus dangerous) setting for the sperm to journey in.
