The bulbourethral glands are two small, rounded, somewhat lobulated formations, yellow in color and pea-sized. They are close to the bulb and surrounded by transverse fibers of the urethral sphincter. They are located inferiorly to the prostate and drain its secretions (Mucosa) to the spongy part of the urethra.
Its secretion is similar to mucus, it enters the urethra during sexual arousal. They constitute 5% of seminal fluid.
During sexual arousal, the bulbourethral glands secrete an alkaline substance that protects sperm and also secretes mucus, which lubricates the tip of the penis and the lining of the urethra, reducing the amount of sperm damaged during ejaculation.
