Why Does The Penis Shrink?

One of the most frequent topics I have heard men talk about is the issue of penis shrinkage. Come to think of it, most men would want to increase the size of their penis. And now here comes the issue of the penis shrinking. As hard a pill this issue is to swallow; it’s possible.

In reality, the penis can shrink or decrease by up to an inch or more. The decrease can also be less than an inch. To set the records straight, the shrinkage will not prevent you from enjoying a satisfying and active sex life.

The concern here is usually on self-esteem as it is believed that women love men with a big penis. Moving on, let’s find out what causes the penis to shrink.

Things that can lead to penis shrinkage:


One of the major culprits of penis shrinkage is obesity. This is more obvious in men that gain weight around their lower abdomen. Once you start adding weight as a man in this part of your body, you will notice that the shaft of your penis is gradually covered by a thick pad of fat. When this happens, your penis will appear shorter when you look down at it. If you keep up with the weight increase, you might discover that fat encloses most of your penis.


This is an inevitable part of life as all human beings must age at some point in life. Aging comes with a decline in the way the body originally functions. And so, when it comes to the penis, aging can reduce the amount of blood that flows to the penis as a result of fatty deposits in the arteries. What happens is that the muscle cells which are the spongy tubes found in the erectile tissue of the penis begins to wither. It becomes engorged with blood in order to produce erections.

Sports or sex activities over time can lead to scars from repeated small injuries and this can lead to scar tissue building up. You tend to find that your once elastic and supple sheath now has a buildup of scar tissues in the area around the spongy erectile tissues of your penis. This is one of the reasons your penis may appear shorter with fewer erections.

Peyronie’s disease

In case the name sounds strange to you, Peyronie’s disease simply means an extremely curved penis. This situation makes sexual intercourse quite painful or in severe cases impossible. When you have this situation, you will find that the girth and length of your penis appear to have reduced. While mild penis curve can be manageable, when it makes having sex impossible, you might have to opt for surgery to get rid of the scar tissue that causes this. The size of the penis can also reduce in the process of scar tissue removal.

If at any point you start noticing that your penis is curving and is accompanied with swelling and pain, it could be Peyronie’s disease. You may need to consult your doctor or a urologist for treatment.

Prostate surgery

Another thing that can cause the penis to shrink is when a man undergoes a prostate surgery (radical prostatectomy) to remove a cancerous prostate gland. The shortening is not so huge but can happen in up to 70% of men that undergo this surgery.

It is not yet clear why the size of the penis reduces after such surgery but there are some things that could be responsible for this. Experts note that there is usually an abnormal muscle contraction that happens in a man’s groin which results in the penis being pulled farther into the body.

Also, the surgery might make it difficult for the man to get an erection. This means that the erectile tissue will lack oxygen and will ultimately lead to the shrinking of the muscle cells found in the spongy erectile tissue. Once again, the issue of scar tissues forming around the erectile tissue becomes another thing to worry about.

However, not all men experience shortening of the penis after undergoing prostate surgery. Speaking with your doctor before undergoing this procedure will help in calming your fears.

Are there solutions or treatment to penis shrinkage?

The answer to that is yes, there is something that can be done to prevent the penis from shrinking or at least restore it back to its normal length.

For obesity, this is more manageable than other issues mentioned in this article. If your penis is shrinking as a result of weight gain, you can reverse this by losing the extra weight. Get more active and get rid of junk foods. Choose a healthy balanced diet instead and watch your body as well as your penis return back to its original state.

For aging, some of the things mentioned in obesity can be applied here. You can reduce the process of aging by living an active and healthy lifestyle. You might also want to steer clear of smoking and only take alcoholic drink in moderation.

It is also important to maintain an adequate sex life as it helps in maintaining erectile function. When an erection occurs, the penis is filled with oxygen-rich blood that can prevent the penis from shortening.

For Peyronie’s disease, not much can be done here as not much can be done about the shortening. The main concern here is to get your sex life back by having the scar tissue buildup removed.

And for prostate surgery, most of the time, the penis shortening will reverse on its own within 6 months to 1 year. All that is required here is some patience.

Your doctor might also suggest penile rehabilitation which entails taking erectile dysfunction pills like Viagra and a vacuum device to encourage blood flow to the penis. While this procedure may not work 100%, you may want to give it a try, especially if you are having a problem getting an erection after surgery.

Finally, while many men would not want their penis to shrink for any reason, it does not mean that their sex life will be affected. If the penis shrinkage is something you can do something about, then, by all means, do it. Always remember to place your health first while at it.
