The majority of penile fractures occur with direct trauma during sexual intercourse.
Direct trauma to an erect penis results in increased pressure in the cavernosa. This increased pressure, in turn, results in the rupture of the tunica albuginea, the fibrous envelope that extends the length of the penis. SOURCE.

IMPORTANT SAFETY INFORMATION FOR XIAFLEX®
XIAFLEX® can cause serious side effects, including penile fracture (corporal rupture) or other serious injury to the penis. Receiving an injection of XIAFLEX® may cause damage to the tubes in your penis called the corpora.
After treatment with XIAFLEX®, one of these tubes may break during an erection. This is called a corporal rupture or penile fracture. This could require surgery to fix the damaged area. Damage to your penis might not get better after a corporal rupture. SOURCE.
What Is Peyronie’s Disease?
By James Myhre & Dennis Sifris, MD Published on March 24, 2023 | Medically reviewed by Jamin Brahmbhatt, MD
VERYWELL HEALTH – Peyronie’s disease (PD) is a condition in which the penis develops an abnormal curve. The bend is due to the buildup of scar tissue, called plaques, on the membrane surrounding the inner shaft of the penis.
PD tends to affect older people and can cause painful erections, pain with intercourse, and erectile dysfunction (ED). Treatment includes medical-grade penile injections, penile traction therapy, and surgical correction.1
PD is a benign (noncancerous) condition but one that can cause considerable stress and a loss of sexual function, affecting a person’s self-esteem and relationships.
This article describes the symptoms and causes of Peyronie’s disease and what can be done to diagnose, treat, and cope with a condition that affects up to 11% of people with penises in the United States.2
Penises can have some degree of curvature that you are born with and that is perfectly normal. Peyronie’s disease refers to a change in the curvature of the penis that can either evolve over time or occur spontaneously.
Common symptoms of PD include:
- An abnormal curve, usually upward but sometimes downward or to the side
- A curve with or without an erection
- A hardened divot or indentation at the junction of the bend
- Pain with an erection and, less commonly, without an erection
- Pain during intercourse
- Difficulty with penetrative sex
- Narrowing of the penis shaft around the junction of the bend
- A shortening of the penis due to the contraction of tissues
Beyond the deformity of the penis itself, PD is associated with an increased risk of erectile dysfunction (ED). The loss of erectile function may occur with the onset of PD symptoms, develop months or years later, or make existing ED symptoms worse.
The penile plaques can stem the flow of blood needed to engorge the penis during an erection. It can also disrupt the function of smooth muscles around the penis that stiffen during an erection.
Risks of Erectile Dysfunction
Studies suggest that anywhere from 40% to 60% of people with Peyronie’s disease have some degree of erectile dysfunction.5 However, as PD tends to affect older people who are already at risk of ED, it may be a contributing rather than the sole cause of ED …
