BULBOURETHRAL GLANDS ANATOMYJust below the prostate gland there are two small glands, about the size of a pea, known as either the bulbourethral glands or Cowper’s glands.
These glands individually measure about 1 centimeter in diameter and drain via a 2 ½ centimeter tube into the urethra.
The purpose of these glands is to respond to sexual arousal by releasing a coating enzyme into the urethra to neutralize the Ph level left behind by urine.
In the most common explanation, it is the cleansing system of the penis. This occurs to prevent early death of sperm cells during ejaculation. It also helps to provide the penis with ample lubrication before sexual activity.
