Everything about Cowper S Glands totally explained
A
bulbourethral gland (or
Cowper's gland) is one of two small
exocrine glands present in the
reproductive system of human males. They are
homologous to
Bartholin's glands in females.
Location
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 bytransverse fibers of the
sphincter urethrae membranaceae muscle.
Structure
The bulbourethral glands are compound tubulo
alveolar glands, each approximately the size of a pea. They are composed of several
lobules held together by a fibrous covering. Each lobule consists of a number of
acini, lined by columnar
epithelial cells, opening into a duct which joins with the ducts of other lobules to form a single excretory duct. This duct is approximately 2.5 cm long and opens into the urethra at the base of the penis. The glands gradually diminish in size with advancing age.
Function
During
sexual arousal each gland produces a clear, viscous secretion known as
pre-ejaculate. This fluid helps to lubricate the urethra for spermatozoa to pass through, it neutralizes traces of acidic urine in urethra, and helps flushing out any residual urine or foreign matter. It is possible for this fluid to pick up
sperm, remaining in the
urethral bulb from previous ejaculations, and carry them out prior to the next ejaculation.
