Peyronie's disease

Also called Penile curvature

Peyronie's disease is a condition where a hard lump of scar tissue (plaque) forms in the penis, causing it to bend or change shape when erect. It may follow an injury to the penis, but often the cause is not known. It mostly affects men over 40.

What it is

In some men it settles by itself. Pain often eases within 12 to 18 months, but the bend may stay.

Medicines, injections, a device to straighten the penis, or surgery may be offered if the bend makes sex difficult.

Common signs

  • A bend in the penis when erect
  • A lump in the penis
  • Pain in the penis, especially during an erection
  • Problems getting or keeping an erection
  • The penis becoming shorter

How it is usually diagnosed

  • Examination
  • Photos of the erect penis to show the bend
  • Sometimes an ultrasound scan

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Urology letters
  • Ultrasound reports
  • Treatment plans

Questions to ask your doctor

  • Is the condition still changing?
  • What treatment options do I have?
  • Will treatment affect erections?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden pain with a cracking sound and swelling of the penis during sex: get urgent help, call 112
