Why Penis Length Can Decrease Over Time—and What You Can Do About It
It may come as a surprise, but erections can gradually become shorter with age. This change is commonly linked to reduced blood circulation to the penis as arteries slowly accumulate plaque over time. When blood flow drops, the muscle cells responsible for erections weaken, making it harder for the penis to reach the same height as before.
Aging, weight gain, medical conditions, and smoking can all influence erection length. Learn the exact reasons, health links, and when to see a doctor.
As arteries become increasingly obstructed, erectile dysfunction (ED) can develop. In addition, the erectile fibers that allow the penis to expand may lose some of their elasticity over the years. This can slightly reduce maximum length, usually by very small amounts.

Still, growing older does not automatically mean erection problems. According to Dr. Bole, men who preserve good cardiovascular health and strong blood vessels may never notice any decline in erection quality or length.
How Weight Gain Plays a Role
Gaining weight can also affect perceived penis size. Extra fat that builds up in the pubic area below the abdomen may partially cover or “bury” the penile shaft, making it look shorter than it actually is.
In severe cases, particularly when body mass index reaches 40 or above—classified as class III obesity—a condition known as buried penis may occur. Dr. Bole notes that losing weight often improves the situation. However, if complications such as difficulty urinating, pain, or repeated infections arise, surgery may be advised to remove excess tissue surrounding the penis.
Medical Conditions That Can Impact Length
Several health-related issues may contribute to changes in penis length:
I. Peyronie’s disease: This condition involves the buildup of scar tissue, causing the penis to curve during erections and reducing usable length. Thickness may also be affected.
II. Penile injury: Trauma to penile tissue can result in scarring, which limits expansion since scar tissue lacks elasticity.
III. Prostate surgery: Men who undergo prostate removal for prostate cancer may experience a shortening of about 0.4 inches (1 centimeter). Studies show that length often returns within two to four years.
IV. Cardiovascular problems: Reduced circulation leads to weaker erections, and softer erections can sometimes be an early indicator of heart disease.
Treatments are available for these conditions and may help regain some length or prevent further changes. Speaking with a healthcare provider is essential to explore appropriate options.
Smoking and Its Effects
Smoking doesn’t just harm the lungs—it can also affect erection length. Long-term tobacco use restricts blood flow to the penis, which, as already noted, weakens erections. Smoking may also reduce the elasticity of penile tissue.
Dr. Bole explains that smokers face a higher risk of erectile dysfunction, Peyronie’s disease, and other conditions that influence penis size. The encouraging news is that quitting smoking can improve circulation and reverse some of these effects.
When You Should Talk to a Doctor
If your erections consistently fall short of what they once were, Dr. Bole advises consulting a doctor to identify the cause. Such changes may point to an underlying health concern that needs attention.
“Your sexual health often reflects your overall health,” Dr. Bole emphasizes. “If you notice an unexpected difference in your erections, start the conversation. We can help you find answers.”
