A bulbourethral gland, also called a Cowper gland 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 only absent in the dog).They are homologous to Bartholin's glands in females.he bulbourethral glands are compound tubulo-alveolar glands, each approximately the size of a pea in humans. In chimpanzees, they are not visible during dissection, but can be found on microscopic examination. In boars, they are up to 18 cm long and 5 cm in diameter.
In the case of the bulbourethral gland, such secretions leave the body through the urethra. A clear, colorless, and somewhat viscous component of pre-ejaculatory fluid, known as Cowperâs fluid, is discharged by the bulbourethral gland into the urethra when the male becomes sexually aroused. It is then secreted out of the body through the urethra before ejaculation.
