Penis shrinking can result from conditions such as diabetes, cardiovascular problems, Peyronie’s disease, and priapism. The absence of involuntary night-time or morning erections and certain medical treatments can also reduce size. Clear up your doubts about penis dimensions.

Can a penis really shrink in size? Few men know this, but the penis can indeed lose length. Of course, it never happens by chance. Penile reduction is usually linked to conditions that cause erection difficulties or internal fibrosis.

If this subject worries you, don’t panic. In this post I’ll detail the causes, the precautions, and how you can assess whether your buddy needs medical help. The good news is that treatment exists.

Some ways to check if the penis has shrunk

First of all, take a look at your penis size. To get a good idea, you should measure it while standing and fully erect. Use an easy reference such as your hand, fingers, a ruler, or the distance to your navel for periodic comparison. If you notice poor erection quality, I advise you to see a urologist for a more accurate diagnosis, since self-assessment will only be precise if the penis is fully rigid. With medical guidance you can have a Doppler ultrasound after an induced erection to evaluate internal structures, blood flow, and the presence of superficial or internal fibrosis that can leave the penis shrinking.

Conditions that cause penis shrinking

Penile shortening is linked to certain medical and surgical conditions that usually lead to erectile dysfunction. Below you’ll understand each of them.

Absence of involuntary night-time or morning erections

You know when you wake up in the middle of the night, or in the morning, and notice your penis is erect without any sexual stimulus? This is perfectly normal and should happen fairly regularly when penile health is good. If these erections disappear the penis becomes less oxygenated, which can promote fibrosis over time.

Be alert: it may be related to hormonal imbalance or a more serious erectile-dysfunction issue. If you have had erection problems for some time or noticed a significant reduction in penile size in recent years, get in touch through this link so we can plan an in-person evaluation.

Prostate-cancer treatment

Surgery, radiotherapy, brachytherapy, or hormone therapy—methods for treating prostate cancer—are highly associated with side effects such as erectile dysfunction, fibrosis, and penile shortening. Learn about other consequences of prostate cancer, how to prevent them, and how to treat each one.

Treatment of erectile dysfunction

Continuous use of pills and injections to stimulate erection often causes side effects that create scars in the penis and can develop into fibrotic plaques. These plaques can cause not only shortening but also curvature and narrowing of the penis.

Patients with diabetes

Diabetes is linked to elevated blood-sugar levels. Poor control damages nerves and blood vessels, which can lead to erectile dysfunction. Because erection difficulty encourages fibrosis in penile tissue, it can also cause the penis to shrink.

Patients with cardiovascular problems

Cardiovascular conditions, such as arteriosclerosis, can slow blood flow inside the penis, hampering erection capacity and causing penile shortening in addition to preventing satisfactory sexual intercourse.

Patients who developed Peyronie’s disease

Peyronie’s disease is caused by fibrotic plaques that can affect both sides of the penis. This situation impacts not only curvature but can also cause significant length reduction and worsen erection problems.

Patients who had priapism

Priapism is a very prolonged erection without physical or psychological stimuli. Besides being very painful, it can lead to serious consequences such as irreversible erectile dysfunction, necrosis, and internal fibrosis of the corpora cavernosa—responsible for reducing penile length and girth.

Considerations on penis size and penile implant

The first thing men think when penis shrinking is linked to a penile implant is that it will enlarge the organ. As we’ve seen, that’s a myth.

The implant is designed to give rigidity and firmness to the penis. Before surgery, the doctor must evaluate and identify any expected size reduction. This penis-shrinking issue can be corrected during the same implant surgery through penile reconstruction, bringing more comfort and satisfaction to the patient. This is the great advantage of the Egydio Technique.

How many centimetres can the penis shrink?

According to scientific studies, the penis can shrink between 1.5 and 3.5 centimetres. This loss of length usually occurs gradually. One contributing factor is penile micro-trauma—small injuries that can arise, for example, during poorly lubricated sex. Because these traumas often don’t cause immediate pain, they go unnoticed but can, over time, affect the organ’s structure and length.

“I’m not sure whether my penis has shrunk.”

This doubt is very common among patients experiencing penis shrinking. Some men easily notice size reduction; others can’t tell because of erection problems. In any case, it’s important to seek medical help for a more accurate diagnosis and appropriate treatment.

I understand this is a delicate subject and can feel embarrassing. I’m here to listen and provide the necessary medical guidance with confidentiality and discretion.
