Penile curvature can be corrected through several approaches depending on the cause, severity, and how long you’ve had it. The options range from traction devices and injections to surgery, but the right path depends on whether the curvature is something you were born with or something that developed later, usually from a condition called Peyronie’s disease.
A slight curve during erection is normal and doesn’t need treatment. If the curve is significant enough to cause pain, make sex difficult, or cause distress, there are effective ways to address it.
What’s Causing the Curve Matters
There are two main reasons a penis curves, and they’re treated differently. Congenital curvature is present from birth, caused by uneven development of the tissue inside the penis. There’s no scar tissue or plaque involved. Some men notice it during puberty when erections become more frequent. Because there’s no underlying disease process, congenital curvature doesn’t change over time, and surgery is the primary fix when it’s bothersome.
Peyronie’s disease is an acquired condition where scar tissue (called plaque) forms inside the penis, pulling it in one direction. It typically develops after repeated minor injuries during sex or physical activity, though many men don’t recall a specific event. Peyronie’s goes through two distinct phases, and understanding which phase you’re in determines what treatments are appropriate.
The Two Phases of Peyronie’s Disease
The active phase is when things are changing. The curve may be getting worse, you might feel pain during erections or even at rest, and the plaque is still forming. This phase typically lasts 12 to 18 months from the onset of symptoms. During this time, the goal is to slow progression and manage pain rather than attempt a permanent correction. Surgery performed too early risks correcting a curve that hasn’t finished developing.
The stable phase begins once symptoms have stopped changing for at least three months. Pain usually fades, and the curve has settled into its final shape. This is when corrective treatments, especially surgery, become viable options. A urologist will confirm stability based on your symptom history before recommending any permanent intervention.
Traction Devices
Penile traction therapy uses a mechanical device to apply gentle, sustained stretching to the penis. The idea is to remodel the scar tissue over time, gradually reducing the curve. Traditional traction devices required 2 to 9 hours of daily use, which made them impractical for most men. Newer devices have been designed to achieve results with shorter sessions, around 30 minutes once or twice daily.
Traction works best during the active phase to slow worsening, or alongside other treatments. The improvements tend to be modest, typically a few degrees of correction. The main advantages are that traction is noninvasive, can preserve or even improve length, and carries minimal risk. The main drawback is commitment: you need consistent daily use over several months to see any benefit.
Injection Therapy
For men with stable Peyronie’s disease, injections directly into the plaque can reduce curvature without surgery. The most studied option uses an enzyme that breaks down the collagen in scar tissue. Treatment involves a series of injection cycles spaced over several months, combined with gentle stretching exercises at home.
Results are real but moderate. In clinical data from the Sexual Medicine Society of North America, men started with an average curvature of 47 degrees and ended at about 40 degrees after treatment. Overall, 44% of men saw improvement, 39% had no change, and 17% actually worsened. Interestingly, the worse the starting curve, the better the odds of improvement: 29% of men with curves of 30 degrees or less improved, compared to 60% of men with curves of 60 degrees or more.
Injection therapy is best suited for men with moderate curvature (30 to 90 degrees) who want to avoid surgery. Side effects can include bruising, swelling, and in rare cases, penile fracture, so treatments are administered carefully by a specialist.
Surgical Options
Surgery offers the most reliable correction and is considered once the disease has been stable for at least three months. There are three main approaches, chosen based on curve severity, erectile function, and how much length you can afford to lose.
Plication
This is the simplest surgical option. The surgeon places stitches on the longer side of the penis (opposite the curve) to pull it straight. It’s most effective for curves under 60 degrees when erections are still firm. The trade-off is some shortening on the longer side, which can be noticeable depending on the severity of the original curve. Recovery is relatively quick, and complication rates are low.
Plaque Excision and Grafting
For more severe or complex curvatures, the surgeon removes the scar tissue and patches the gap with a graft. This approach preserves more length. In a study of 240 men who underwent grafting procedures, about 80% were able to have penetrative sex afterward. Recurrent curvature occurred in roughly 12% of cases, and a small percentage (6 to 13%) experienced some decrease in penile sensation. Grafting resulted in a slight average length gain rather than loss, with men gaining about half a centimeter on average. This procedure is more complex than plication and requires stronger baseline erectile function.
Penile Implant
When Peyronie’s disease occurs alongside significant erectile dysfunction, a penile implant can solve both problems at once. An inflatable prosthesis is placed inside the penis, and the act of inflating the device often straightens the curve on its own. In one study, all men who received a specific type of inflatable implant achieved complete straightening through inflation and manual modeling alone. About 79% of men reported high satisfaction after the procedure, and 82% said they would choose the same operation again. This is reserved for men whose erections are too weak for other surgical options to work.
What Doesn’t Work
Oral supplements, particularly vitamin E, are widely promoted online for Peyronie’s disease. The American Urological Association’s clinical guidelines do not support their use. No oral supplement has been shown to meaningfully reduce penile curvature in well-designed studies. Taking vitamin E or similar products during the active phase is unlikely to cause harm, but it’s also unlikely to change the outcome.
Shockwave therapy is another treatment you’ll encounter in online searches. While low-intensity shockwave therapy has some evidence for improving blood flow in erectile dysfunction, current guidelines do not recommend it as a curvature correction tool. It may help with pain during the active phase, but it won’t straighten the penis.
Choosing the Right Approach
The best treatment depends on where you are in the process and how much the curve is affecting your life. During the active phase, when things are still changing, traction and monitoring are the most appropriate steps. Trying to fix a moving target with surgery or injections often leads to disappointment or repeat procedures.
Once the curve has stabilized, your options open up. For mild to moderate curves with good erections, plication is straightforward and effective. For severe or complex curves with good erections, grafting preserves more length. For curves combined with erectile dysfunction, an implant addresses both issues. Injections sit in the middle as a less invasive alternative for men who want to avoid the operating room, with the understanding that results are more modest and less predictable.
A urologist who specializes in sexual medicine can measure the degree of curvature, assess erectile function, and recommend the approach that fits your specific situation. The curve’s direction, degree, and whether you have any hourglass or hinge deformity all factor into the decision.
