Penile curvature can be reduced or corrected through several approaches, ranging from at-home traction devices to injectable treatments and surgery. The right option depends on what’s causing the curve, how severe it is, and whether it’s affecting sexual function. Most mild curves don’t need treatment at all, but when curvature reaches 30 degrees or more and interferes with sex or causes pain, effective treatments exist.
Why the Penis Curves
There are two main reasons a penis curves. The first is congenital curvature, which you’re born with and typically notice during your teenage years. This type doesn’t involve any scar tissue and generally stays stable over time. It doesn’t get worse, and erections aren’t painful.
The second and more common cause is Peyronie’s disease, an acquired condition that typically develops in a man’s 50s or 60s, though it can appear earlier. Peyronie’s starts with small injuries to the tough outer layer of erectile tissue, often from bending or buckling during sex. In some men, the healing process goes haywire. Instead of repairing normally, the body lays down excessive scar tissue (called plaque) that doesn’t stretch the way healthy tissue does. When you get an erection, the scarred side can’t expand as much as the other side, pulling the penis in that direction. This can also cause indentations, a hinge-like weak point, or shortening.
Peyronie’s disease has two phases. The acute phase, lasting roughly 12 to 18 months, involves active inflammation where the curvature may still be changing and erections can be painful. The stable phase comes after, when the plaque has matured and the curve stops getting worse. Most treatments work best once the disease has stabilized.
When Treatment Is Worth Pursuing
There’s no official minimum curvature that requires treatment. In clinical studies, men who sought intervention had curves ranging from 10 to 90 degrees, with a median of about 48 degrees. The real question is whether the curve is causing problems: pain, difficulty with penetration, or psychological distress. A slight bend that doesn’t interfere with sex is normal and doesn’t need correction.
Injectable and surgical treatments are typically recommended for curves greater than 30 degrees in men with stable disease. If your curve is still actively changing or erections are still painful, your urologist will likely recommend waiting until things settle before pursuing correction.
Traction Devices
Penile traction therapy is one of the least invasive options with real evidence behind it. A 2019 review found that penile stretching is an effective therapy for Peyronie’s disease specifically, even though stretching exercises don’t have good evidence for other purposes like increasing size.
The catch has historically been the time commitment. Older data suggested you’d need to wear a traction device three to eight hours a day for up to six months for modest improvements. Newer devices have shortened that considerably. A randomized controlled trial tested a newer traction system used for just 30 to 90 minutes daily over three months and found meaningful results. Traction works by gradually remodeling the scar tissue, and it’s sometimes used alongside other treatments to maximize improvement or prevent shortening after surgery.
Vacuum erection devices (the pump-style devices) also show some promise. One study found a significant decrease in curvature after 12 weeks of using a vacuum pump for 10 minutes twice daily. The mechanism is similar: the stretching force helps break down and remodel the plaque over time. In a six-month trial, men using a vacuum pump saw an average curvature reduction of about 7 degrees, with slightly better results when combined with shockwave therapy.
Injectable Treatment
For men with curves between 30 and 90 degrees who have stable disease and can still get erections, an injectable enzyme treatment is available that breaks down the collagen in the scar tissue. The treatment involves a series of injection cycles, each consisting of two injections spaced one to three days apart, repeated every six weeks. After each cycle, the provider manually models (bends) the penis to help break up the weakened plaque, and you’re also instructed to do gentle stretching at home between visits.
Men who completed all four cycles of treatment saw an average curvature reduction of about 20%. So if you started at 50 degrees, you might expect a reduction of roughly 10 degrees. That may sound modest, but for many men it’s enough to make sex comfortable again. The treatment tends to work progressively, with each cycle adding to the improvement.
Surgical Correction
Surgery offers the most dramatic and reliable straightening, but it’s reserved for men with stable disease whose curvature is severe enough to impair sexual function. There are three main surgical approaches, and the choice depends on how much curvature you have and how well your erections work.
Plication
This is the simplest option. The surgeon places stitches on the longer side of the penis (opposite the plaque) to shorten it so it matches the scarred side, pulling the penis straight. It’s a faster procedure with fewer complications. Men who undergo plication are less likely to experience loss of rigidity or sensation compared to more involved surgeries. The tradeoff is some degree of shortening, since you’re essentially tucking the longer side. Some men notice small palpable bumps at the stitch sites.
Plaque Incision or Removal With Grafting
For more severe curves, the surgeon cuts into or removes the plaque itself and patches the gap with graft tissue. This approach can correct larger deformities while preserving more length than plication. However, it carries a higher risk of reduced erectile rigidity, decreased sensation, and difficulty with intercourse afterward. In studies comparing the two approaches, patient satisfaction rates were similar, and both groups reported comparable levels of perceived shortening, which is a common complaint regardless of surgical technique.
Penile Prosthesis
When Peyronie’s disease occurs alongside erectile dysfunction that doesn’t respond to medication, an inflatable prosthesis can address both problems at once. The device itself helps straighten the penis during inflation, and the reliable erections it produces prevent the kind of buckling injuries that caused the scarring in the first place.
Recovery After Surgery
Following plication surgery, you’ll need to avoid all sexual activity, including masturbation, for six weeks. The plication procedure has a shorter operating time and generally faster recovery than grafting. Grafting procedures involve a longer recovery window and carry more risk of changes to erection quality and sensation. Your surgeon will give you a specific timeline based on how things heal.
What Doesn’t Work
Manual stretching exercises like jelqing have little evidence supporting their effectiveness for curvature correction, and they carry real risks. Broken blood vessels, bruising, numbness, and tissue inflammation are all possible side effects. Worse, improper technique or overdoing it can damage the erectile tissue itself, potentially leading to weaker erections. This is especially important if your curvature is caused by Peyronie’s disease, since the underlying problem is scar tissue from injury. Aggressively stretching or bending the penis on your own could trigger more of the exact scarring you’re trying to fix.
Various supplements, creams, and oral medications marketed for Peyronie’s disease have also failed to show reliable benefit in rigorous studies. If you see a product promising to straighten your penis without a prescription or medical supervision, the evidence isn’t there.
Choosing the Right Approach
For mild curvature that’s recently developed and still in the acute phase, traction therapy is a reasonable starting point. It’s low risk, can be done at home, and may slow or reduce the curve while things stabilize. For moderate stable curves in the 30 to 60 degree range with good erectile function, injectable treatment combined with traction is a solid nonsurgical path. For severe curvature or cases where nonsurgical options haven’t helped enough, surgery provides the most definitive correction. And for men dealing with both curvature and erectile dysfunction, a prosthesis solves both issues simultaneously.
A urologist who specializes in sexual medicine can measure your curvature precisely, determine whether the disease is still active or has stabilized, and help you weigh the realistic benefits and tradeoffs of each option.
