When Your Penis Takes a Left (or Right, or Up, or Down)Turn: The Truth About Peyronie’s Disease
Dr. Robert Bonzani, M.D.
If you’ve ever noticed your penis curves to one side, you’re not alone—and you’re not broken. Many men have some natural curvature, and mild bends are usually nothing to worry about. But for some, the bend is caused by Peyronie’s disease, a condition that affects a small portion of men and can develop over time.
You’ve probably seen TV commercials comparing Peyronie’s to fruit—like bent bananas or crooked cucumbers. While those images are memorable, they don’t tell the full story. Peyronie’s isn’t a joke, and it isn’t permanent if addressed. It’s a condition that can be treated, and men with it are more common than most people realize.
What Really Happens
Peyronie’s disease occurs when fibrous scar tissue (plaque) develops inside the penis, creating a bend or curve. This can happen in any direction—up, down, left, or right—and usually develops slowly over months.
Here’s what typically happens over time:
Early Phase (Inflammatory Stage)
Pain during erections is common
Curvature may gradually increase
The penis may feel firm or lumpy in areas of plaque
Stable Phase (Chronic Stage)
Pain usually subsides
Curvature generally stabilizes
Sexual function may be affected if the bend is severe
Spontaneous improvement is uncommon, but treatments are available
Why You Shouldn’t Feel Abnormal
Mild penile curvature is extremely common—up to 30–40% of men have some natural bend. Peyronie’s disease is different because it may develop later in life and sometimes causes discomfort or makes sexual activity difficult. But even when Peyronie’s occurs, it’s treatable.
Treatment Options
Treatment depends on severity and symptoms. Most mild cases may not need intervention, but for those who need correction:
Non-surgical options
Collagenase injections (Xiaflex - FDA-approved) can help reduce curvature
Traction therapy or vacuum devices may gradually straighten the penis, although this process oftentimes does not work).
Surgical options
Plication (shortening the opposite side)
Plaque incision or excision with grafting
Penile prosthesis (for severe cases with erectile dysfunction)
A board-certified urologist can help guide the best option based on your anatomy and goals.
Bottom Line
Peyronie’s disease happens, but it doesn’t define you. Most men experience minor bends naturally, and even when curvature is more pronounced, treatment is available. What matters is recognizing the condition, understanding that it’s common, and knowing you can seek help from a trained urologist—someone who knows exactly how to manage it safely and effectively.
So if your penis has “taken a left turn,” don’t panic. You’re normal, you’re not alone, and there are solutions.
