Chordee is a congenital curvature of the penis, present from birth, caused by uneven development of the penile tissue during fetal growth. It most commonly curves downward (ventrally) and is frequently found alongside hypospadias, a condition where the urinary opening is on the underside of the penis rather than the tip. In one registry study, 87% of boys with hypospadias also had some degree of chordee. It can also occur on its own, with a normally positioned urinary opening.
What Causes the Curvature
The penis has a tough elastic sheath called the tunica albuginea surrounding its erectile tissue. In chordee, part of this sheath doesn’t develop normally. The affected area is less elastic than the tissue around it, so during an erection the normal tissue stretches while the stiff portion doesn’t. The result is a bend toward the stiffer side.
When chordee occurs without hypospadias, the cause falls into roughly three equal categories based on a study of 87 patients: skin tethering (tight outer tissue pulling the penis downward), fibrous bands in the deeper tissue layers beneath the skin, and a size mismatch between the two erectile bodies inside the penis. A congenitally short urethra is a rare fourth cause.
How Chordee Differs From Peyronie’s Disease
The key distinction is timing. Chordee is congenital, meaning the curvature has been present since birth even if it only becomes noticeable during erections later in life. Peyronie’s disease is acquired, typically developing in adulthood when scar tissue (plaque) forms inside the penis after injury or inflammation. The two conditions involve different tissue problems and are managed differently.
How It’s Diagnosed
Mild chordee may not be obvious in a newborn. It often becomes apparent during diaper changes when an infant has a spontaneous erection, or parents may notice the downward curve over time. In some cases, it isn’t recognized until puberty when erections become more frequent and the curvature becomes functionally noticeable.
During a surgical evaluation, doctors use an artificial erection test to measure the exact degree and direction of curvature. This involves injecting saline into the erectile tissue while the child is under anesthesia. A newer, non-invasive alternative works by manually pressing at the base of the penis to trap blood and create firmness without an injection. The severity of the curve guides decisions about what type of repair is needed.
When Surgery Is Recommended
There is broad consensus that corrective surgery should happen between 6 and 18 months of age when the condition is identified early. Operating in this window takes advantage of the child’s rapid healing, minimizes psychological impact, and allows the repair to grow with the child. For older children, teens, or adults who weren’t diagnosed earlier, surgery can still be performed but may involve more complex techniques.
Not every case requires surgery. Very mild curvature that doesn’t interfere with urination or, later in life, sexual function may simply be monitored. Surgery is typically recommended when the curvature is significant enough that it would cause functional problems.
What Surgery Involves
The surgical approach depends on what’s causing the curve. In roughly a third of cases, simply releasing the tight outer skin and superficial tissue is enough to straighten the penis. Another third require removal of deeper fibrous bands beneath the skin. The remaining cases involve correcting a mismatch in the erectile bodies themselves, which is a more involved procedure.
For most patients, the standard techniques include degloving (pulling back the skin to access deeper tissue) and dorsal plication, where small tucks are placed on the longer side of the penis to match the shorter side. When these approaches aren’t sufficient, particularly in severe or previously repaired cases, surgeons may place a tissue graft on the shorter side to add length and flexibility. Dermal grafts tend to produce better outcomes than other graft types.
Recovery After Surgery
For young children, recovery typically follows a predictable course. The penis is wrapped in a special bandage that stays on until a follow-up visit 7 to 10 days after surgery. A small catheter may be placed to drain urine while the tissue heals. Parents are advised to sponge-bathe their child for the first week, keeping the surgical area dry, and can transition to brief baths or showers after that.
Straddle toys like bouncers, bicycles, and rocking horses are off-limits for at least 3 to 4 weeks. Mild discomfort with urination is normal and resolves on its own with plenty of fluids. Pain is managed with medication for the first 2 to 3 days, then over-the-counter options like ibuprofen. Most children bounce back quickly, though parents should watch for constipation since pain medications can make it worse and straining increases discomfort.
Long-Term Results
Most repairs are successful, but chordee correction isn’t always a one-and-done procedure. In long-term follow-up studies of patients who had surgery in childhood, about 29% reported some degree of persistent curvature, though most of those cases were minor (less than 45 degrees). A similar study found a 20% rate of residual curvature greater than 30 degrees.
Despite these numbers, satisfaction rates are high. In one long-term study, 86% of patients were satisfied with their surgical results. The most common ongoing concerns were minor residual curvature and cosmetic appearance rather than problems with urination or sexual function. In the small percentage of cases where significant curvature persists or recurs, a second procedure can address it, though secondary repairs are more likely to require grafting techniques.
Other potential complications of surgery include fistula (an abnormal connection between the urethra and skin surface, reported in about 11% of long-term cases), wound separation, infection, and narrowing of the urinary channel. These are uncommon and most are correctable with additional minor procedures if they occur.
