Injury or trauma to the penis can be accidental or deliberate. Deliberate penile injury is a particularly violent event that is usually self-induced, or inflicted by a jealous partner or their former lover. Despite the publicity surrounding a case of penile amputation in the USA, deliberate penile injury is rare in Western cultures, but seen more often in the Far East. Common injuries are:

• penile amputation
• penile fracture.

• A 'cracking' noise.
• Pain.
• Bruising.
• Immediate loss of erection.

Bleeding from the urethra may occur if the urethra is damaged.
