A
penis becomes erect when the lining of the cylinder in the penis
becomes engorged with blood. A penis fracture can occur when
there is trauma to the erect penis, resulting in rupture of
the cylinder lining. This very painful injury is often accompanied
by an audible cracking sound, followed immediately by dark bruising
of the penis due to blood escaping the cylinder. In ten to thirty
percent of penis fractures, the urethra is damaged and blood
may be visible at the urinary opening of the penis. |
