A bent penis can be corrected depending on what’s causing it, how severe the curve is, and whether it’s causing pain or interfering with sex. Most penile curvature falls into one of two categories: a curve you’ve had since puberty, or one that developed later in life from scar tissue buildup. The treatments range from traction devices and injections to surgery, and the right approach depends on your specific situation.
Why Your Penis Is Curved
A slight curve during erection is normal and doesn’t need treatment. When the curve is significant enough to cause pain, make sex difficult, or cause distress, it’s worth understanding the underlying cause.
Congenital curvature results from uneven development of the tough outer sheath (called the tunica albuginea) that surrounds the erectile chambers. It’s present from birth but typically becomes noticeable after puberty, when erections become more frequent. The curve is usually downward, though it can go sideways or, less commonly, upward. There’s no scar tissue or plaque involved.
Peyronie’s disease is the more common reason men develop a new curve later in life. It happens when the penis is injured, sometimes during sex or physical activity, and the healing process produces a patch of hard scar tissue (plaque) inside that outer sheath. During an erection, the scarred area can’t stretch the way healthy tissue does, so the penis bends toward the plaque. The typical age of onset is 50 to 60, but it occurs in younger men too, with prevalence reported between 1.5% and nearly 17% in men under 40. You may feel a hard lump under the skin, pain during erections, or notice the curve getting worse over weeks or months.
Active Phase vs. Stable Phase
If you have Peyronie’s disease, treatment timing matters. The condition goes through two distinct stages, and most corrective procedures only work once the disease has stabilized.
The active phase is when symptoms are changing. Pain during erections is the hallmark, and the curve may still be getting worse. This phase can last anywhere from a few months to over a year. During this time, the American Urological Association recommends pain management with anti-inflammatory medications while monitoring the progression.
The stable phase begins once the pain has resolved and the curvature hasn’t changed for at least three months. This is when injectable treatments and surgery become appropriate. Jumping into corrective procedures too early risks treating a moving target, since the plaque may still be developing.
Documenting Your Curvature
Before seeing a urologist, it helps to document your curvature at home. The most practical method is taking a photograph of your erect penis from the side at roughly arm’s length. Urologists have traditionally relied on visual inspection, but photo-based measurement is increasingly common and lets you track changes over time. Some smartphone apps allow you to overlay your photo against reference images representing each 10-degree increment of curvature from 10 to 90 degrees, giving you a reasonable estimate to bring to your appointment.
Traction Devices
Penile traction therapy uses a mechanical stretching device worn on the penis for extended periods. It’s one of the least invasive options and can be used during the active phase without the risks of surgery. The catch is compliance: traditional devices require 2 to 9 hours of daily use to be effective. Newer designs have reduced that to around 30 minutes per day. Treatment protocols typically run for several months. Traction therapy is often used alongside other treatments rather than as a standalone fix, and it may also help preserve penile length, which is a common concern with other interventions.
Injectable Treatments
For men with stable Peyronie’s disease and a curve between 30 and 90 degrees, injections directly into the plaque can break down the scar tissue. The most studied injectable is collagenase, an enzyme that dissolves the collagen fibers making up the plaque. After each injection, a clinician performs a modeling procedure (manually straightening the penis), and patients continue modeling exercises at home between visits.
A standard course involves up to eight injections. In clinical data, men who completed the full course or stopped early because they were satisfied saw a median curvature improvement of about 27.5 degrees, roughly a 41% reduction. A newer injection technique has shown even better results, with median improvements of 34 degrees (58% reduction) among men who completed treatment. Not every patient responds equally, but for moderate curves with intact erectile function, injections avoid the risks and recovery time of surgery.
Another injectable option uses a protein that helps regulate scar tissue formation. It’s appropriate for men with curves over 30 degrees and plaques that haven’t calcified (hardened with calcium deposits).
Surgical Options
Surgery is reserved for men with stable disease whose curvature is severe enough to prevent satisfactory sex. There are three main approaches, chosen based on the degree of curvature and whether erectile function is intact.
Plication
This is the simplest surgical option. The surgeon shortens the longer side of the penis by placing permanent stitches in the tunica albuginea opposite the plaque, pulling the penis straight. It works best for men with adequate erections and moderate curvature. The tradeoff is some penile shortening, since you’re cinching one side rather than lengthening the other.
Plaque Incision or Excision With Grafting
For more severe curves or complex deformities, the surgeon cuts into or removes the plaque and patches the area with a graft. This approach can correct larger curves while preserving more length than plication. It requires adequate erectile function, since the procedure doesn’t address the ability to get an erection. Recovery is longer than with plication.
Penile shortening is a common complaint after both plication and grafting procedures. Studies comparing the two approaches have found no significant difference in how much shortening patients report, so this concern applies regardless of which technique is used.
Penile Prosthesis
When Peyronie’s disease occurs alongside erectile dysfunction that doesn’t respond to medications or vacuum devices, an inflatable penile implant addresses both problems at once. The implant’s cylinders physically straighten the penis when inflated. Up to 90% of men with penile curvature are sufficiently straightened by cylinder inflation alone, without needing additional corrective steps during the same surgery. Patient satisfaction rates are high, and the implant provides a permanent solution for both the curve and the erection difficulty.
Shockwave Therapy
Extracorporeal shockwave therapy delivers focused sound waves to the plaque. It’s marketed widely, but the evidence is mixed. One comparative study found that 50% of treated patients experienced a 30% decrease in curvature. The more consistent benefit appears to be pain relief rather than curve correction. The UK’s National Institute for Health and Care Excellence has noted that the natural history of Peyronie’s disease (some men improve on their own), high placebo response rates, and a lack of high-quality controlled trials make it difficult to determine how much benefit comes from the shockwaves themselves.
Congenital Curvature Treatment
Since congenital curvature doesn’t involve scar tissue, injectable treatments that target plaque won’t help. The standard correction is surgical plication, the same shortening technique used for Peyronie’s disease. Because there’s no plaque to remove, grafting procedures aren’t typically needed. Men with congenital curvature generally have normal erectile function, so prostheses aren’t part of the picture. The results tend to be straightforward, with high success rates for straightening.
Risk Factors Worth Knowing
Peyronie’s disease is linked to several conditions that affect connective tissue throughout the body. Men with Dupuytren’s contracture (thickening of tissue in the palm that curls the fingers inward) or a similar condition affecting the soles of the feet are at higher risk. During a physical exam, a urologist will often check your hands and feet for these related conditions. Diabetes, which impairs wound healing and blood vessel health, is another established risk factor. Repeated minor injuries to the penis during vigorous sexual activity are thought to trigger the abnormal healing process in men who are predisposed.
