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.
