Peyronie's disease is caused by repeated penile injury, typically during sex or physical activity.
Men's penises vary in shape and size, and having a curved erection isn't necessarily a cause for concern. In Peyronie's disease, the bend is significant, and may occur along with pain or interfere with sexual function.
Medication or surgery may be recommended if symptoms are significant or worsening.
