What are Cowper's glands?
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.
Bulbourethral glands are located posterior and lateral to the membranous portion of the urethra at the base of the penis.
The bulbourethral gland contributes about 5% of the ejaculate. The secretion is a clear fluid that is rich in mucoproteins. The secretion also helps to lubricate the distal urethra and neutralize acidic urine which remains in the urethra.
