Peyronie's disease is the development of fibrous scar tissue inside the penis that causes curvature, narrowing or pain during erection, most often following a minor injury during intercourse that heals with scar tissue instead of normal elastic tissue. It runs in two phases, and which phase you are in, not how much the curve bothers you, determines what treatment is available.

Peyronie's is not a static condition that you either treat or do not. It moves through an acute phase in which the plaque is still forming, and then settles into a chronic phase in which it has stopped. Surgery belongs entirely to the second one, and this is the most common reason a patient is told to wait. Not scheduling, biology.
| Acute phase | Chronic phase | |
|---|---|---|
| What is happening | The plaque is still forming; the angle is still changing | The plaque has matured; the angle is stable |
| Typical duration | Roughly the first 6 to 18 months, though it varies widely | Onward, once change has stopped |
| Pain | Common, particularly with erection | Usually resolved by this point |
| What is offered | Non-surgical treatment and observation | Surgery, once stability is established |
| Why not operate yet | Correcting an angle that is still moving risks correcting it to the wrong one | Not applicable |

Peyronie's most often follows a minor injury to the erect penis (usually during intercourse, and usually an event nobody noticed at the time) that heals with fibrous scar tissue instead of normal elastic tissue. That is why it so reliably feels like it appeared out of nothing. It is associated with Dupuytren's contracture of the hand and with diabetes, which points to an underlying tendency to form scar rather than to anything that happened. It is not caused by masturbation, and it is not a consequence of anything you did wrong.
On erection the affected side stays short while the rest of the shaft expands, which produces curvature, an hourglass narrowing, or a hinge partway along the shaft. Pain is common early and usually settles as the plaque matures. Erectile dysfunction accompanies Peyronie's in a substantial share of cases, sometimes from the disease itself, sometimes because the anxiety it causes becomes its own problem. Whether rigidity is intact is one of only two facts that decide which operation applies. The other is the angle. See /procedures/peyronies-correction/.
