Male Anatomy

In the anatomy of the male human body, the bulbourethral glands (or Cowper's glands) are two small, rounded, and somewhat lobulated bodies, of a yellow color, about the size of peas, placed behind and lateral to the membranous portion of the urethra, between the two layers of the fascia of the urogenital diaphragm. They lie close above the bulb, and are enclosed by the transverse fibers of the Sphincter urethrae membranaceae. Their existence is said to be constant: they gradually diminish in size as age advances. Drawing of the Male Internal Sexual Anatomy From alt. ...
