|Artery of the urethral bulb
Bulbourethral glands are found near the urethra at the base of the penis, between the two layers of the fascia. The bulbourethral glands are about the size of a pea. They appear to slowly get smaller as a person gets older.
They are made of several lobules held together by a fibres.
During sexual arousal each gland makes a clear liquid known as pre-ejaculate or "pre-cum". This fluid helps to lubricate the urethra for sperm to pass through. It also helps clean out any urine or dirt.
