A curved penis can be straightened through traction therapy, injections, or surgery, depending on the cause and severity of the curve. Some degree of curvature is normal and doesn’t require treatment. But if the bend is significant enough to cause pain, difficulty with sex, or distress, several proven options exist. The right approach depends on whether the curve has been present since puberty or developed later in life.
Why the Penis Curves
There are two main causes. Congenital penile curvature results from uneven development of the tough tissue surrounding the erectile chambers. It’s present from birth but usually becomes noticeable after puberty, when erections become more frequent. The curve is most often downward (ventral), though it can bend sideways or, rarely, upward. There’s no scar tissue or plaque involved.
Peyronie’s disease is acquired, meaning it develops later. It typically appears between ages 50 and 60, though it can affect younger men too. The hallmark is a buildup of fibrous scar tissue (plaque) inside the penis that pulls it into a curve during erection. You or your doctor can often feel this plaque as a hard nodule or ridge. Peyronie’s has two phases: an active phase, when the curve may still be changing and erections are often painful, and a stable phase, when the deformity has stopped progressing. That distinction matters because most treatments, especially surgery, are only appropriate once the disease has stabilized, typically 12 to 18 months after symptoms first appear.
Traction Devices
Penile traction therapy is one of the least invasive options and the only non-surgical approach with solid evidence for both reducing curvature and preserving (or gaining) length. It works by applying a gentle, sustained stretch to the penis over weeks and months, gradually remodeling the scar tissue.
In a clinical trial of the RestoreX traction device, men who used it for 30 to 90 minutes daily over three to six months saw an average curvature improvement of 14 degrees and a length increase of 1.8 centimeters. Seventy-seven percent of participants experienced measurable improvement in their curve. Erectile function scores also improved significantly. Continuing use beyond three months yielded additional gains.
The commitment is real: you need to wear the device daily, consistently, for months. But for men in the active phase of Peyronie’s (when surgery isn’t yet an option) or those hoping to avoid an operation, traction therapy is a reasonable first step. Some surgeons also recommend it before or after surgery to maximize results.
Injections for Moderate Curves
For men with stable Peyronie’s disease and a curve between 30 and 90 degrees, injections directly into the plaque can help. The most studied option is an enzyme that breaks down the collagen in scar tissue, delivered through a series of injection cycles followed by gentle manual modeling (bending) of the penis to further disrupt the plaque.
Another injectable option, interferon, has shown benefit in men with curves greater than 30 degrees and no calcified plaque. Both approaches require multiple office visits and work best in carefully selected patients. They won’t eliminate a severe curve entirely, but they can reduce it enough to restore comfortable sexual function.
Oral Medications
Oral treatments for Peyronie’s disease have limited evidence. A study comparing different regimens found that a combination of multiple oral agents produced statistically significant improvements in curvature, plaque size, and erectile function. A commonly discussed single-agent therapy (potassium para-aminobenzoate) showed some improvement but did not reach statistical significance on its own.
During the active phase, when pain is the primary concern, over-the-counter anti-inflammatory medications can help manage discomfort. But no pill alone is likely to straighten a significant curve. Oral medications are best thought of as supportive rather than curative.
Surgery for Stable, Significant Curves
Surgery is the most effective way to straighten the penis and is considered once the disease has been stable for at least three to six months, with a minimum of 12 months since symptoms began. There are two main surgical strategies, chosen based on the severity of the curve.
Plication for Curves Under 60 Degrees
Plication is the simpler procedure. After creating an erection during surgery, the surgeon places a series of stitches on the longer side of the penis (opposite the curve) to “tuck” the excess tissue and bring the penis straight. Think of it like taking in a seam on a piece of clothing. The technique is reliable and carries a low risk of erectile problems afterward.
The trade-off is some shortening. The final length matches the shorter, scarred side of the penis. For mild to moderate curves, this loss is usually modest and acceptable to most men.
Grafting for Curves Over 60 Degrees
When curvature exceeds 60 degrees, plication would require removing too much length from the longer side. Instead, surgeons cut into the plaque on the short side and patch it with graft material, effectively lengthening the concave side to match the other. This preserves more length but is a more complex operation with a somewhat higher risk of changes to erectile function or sensation.
For men who have both severe curvature and erectile dysfunction that doesn’t respond to medication, a penile implant can straighten the penis and restore rigidity at the same time.
What Recovery Looks Like
After plication surgery, most men return to work and daily activities within two to three days. The restrictions that matter most are sexual: no intercourse, masturbation, or oral sex for six weeks. Cycling and similar activities that put pressure on the area should wait four weeks. Submerging the area in water (baths, pools, hot tubs) is off-limits for two weeks.
Surface healing takes about six weeks, but complete internal healing can take several months. Grafting procedures generally involve a longer and more variable recovery, and your surgeon will give you a specific timeline based on the complexity of your case.
Congenital Curvature Is Treated Differently
If your penis has always curved, the cause isn’t scar tissue, so injections and traction therapy aimed at breaking down plaque won’t apply. The standard treatment for congenital curvature that interferes with sexual function is surgical correction, typically a plication technique. Because there’s no plaque involved and the tissue is otherwise healthy, outcomes are generally straightforward with predictable results. A detailed medical history and photos of the erect penis (often taken at home) are usually enough to confirm the diagnosis and plan the procedure.
