7 Causes of Penis Shrinking & What to Do About It

Why is my penis shrinking? If you’ve ever found yourself wondering if your penis is shrinking, then this article is for you. The truth is, penis shrinking is a typical part of male days. However, penis shrinking usually results from feeling cold or a similar cause. This is because, to the ordinary man, it’s natural for your penis to shrink due to a reaction to something.

In this article, we discuss penis shrinkage, both normal and not normal, why the penis shrinks, the causes, and treatments.

What is the Average Penis Size?

Average penile size varies per person. However, average penis size falls within the following ranges:

  • Average length of a flaccid penis: 9.16 centimeters (about 3.6 inches)
  • Average length of a flaccid stretched penis: 13.24 cm (about 5.3 inches)
  • Average length of an erect penis: 13.12 cm (about 5.2 inches)
  • Average circumference of a flaccid penis: 9.31cm (about 3.7 inches)
  • Average circumference of an erect penis: 11.66 cm (about 4.6 inches)

What is Penis Shrinkage?

Can your penis shrink? Yes. “Penis shrinkage” often refers to a reduction in the size of the penis. Shrinkage can directly result from feeling cold, such as a cold shower or exposure to the cold elements. However, penis shrinking might be a permanent result of a treatable disease or poor living conditions for some. Also, men with large amounts of fat in the pubic region can feel that their penis is often retracted and hiding under the fat.

Sometimes called “penile atrophy,” penis shrinkage can be a scary thing to experience. Most men can expect to experience penis shrinking as they age, as it often occurs due to various age-related concerns that many men face.

What Does Penis Shrinking Look Like?

Men will notice two very distinct changes in their penis with age. First, a reduction in blood flow causes the head of the penis (glans) to lose its purple color. Second, there is also a gradual loss of pubic hair. In a sense, the penis reverts to a prepubescent state, mostly hairless. This is often due to men’s natural drop in testosterone as they age. Usually, this can cause the penis to shrink.

What Causes the Penis to Shrink?

Understanding why the penis shrinks is important before looking into treatments. Shrinking can be permanent, and the causes can be linked to a treatable condition or lifestyle changes.

Here are 7 causes of penis shrinking and what to do about it:

#1 Aging

Do penises shrink with age? The truth is, yes, it can. When men age, the fatty deposits in the arteries may cause a reduction in blood flow to the penis. This causes the muscle cells in the erectile tubes to become weak. When the erectile tubes are engorged with blood, they produce fewer erections. Less blood flow means smaller and less firm erections.

As a result of a buildup of scar tissue caused by traumas in the penis, you may experience penis shrinkage. In addition, this buildup of scar tissue can impair the spongy erectile tissue in the penis, limiting erection size and inevitably causing penile atrophy.

#2 Anxiety Shrinkage

Can your penis get smaller when you are anxious? Yes, some men experience anxiety shrinkage. This is known as a psychological phenomenon called “koro.” This is an extreme state of anxiety that causes the penis to shrink or disappear.

#3 Hormone Deficiency

Some studies suggest penile atrophy is a direct correlation of a depletion of androgens, which causes a reduction in smooth muscle cells. In addition, loss of androgens also leads to weight gain, specifically in the pubic area or near the base of the penis.

The loss of hormones potentially has a two-factor effect on penis shrinkage: first, the loss of tissue mass, and then, second, the exposed tissue percentage being reduced to excessive weight gain around the penis.

#4 Peyronie’s Disease

Peyronie’s disease causes fibrous scar tissue to form inside the penis. In response, many men experience penile curvature when the penis begins to curve during erection. A curved erection is cause for concern. In addition, the bend may be uncomfortable for some men.

As men age, they may develop Peyronie’s disease. It can also cause a reduction in the length and circumference of the penis. This often results in the doctor advising you to have surgery to remove scar tissue that causes shrinking, bending, and pain.

#5 Prostate Surgery

Surgeries like a prostatectomy, removing the prostate, can cause the penis to shrink. Some studies also show that the penile dimensions (length and girth) decrease after nerve-sparing radical retropubic prostatectomy. The most substantial changes occur between 4 to 8 months after the surgery. Change is usually about 20%, depending on your health and body. Experiences will be different for everyone.

#6 Radiation

Radiation is another thing that tends to suppress androgens, resulting in penis shrinkage. It was discovered that there’s a “statistically significant decrease” in penile length in men who undergo radiation treatments.

It’s possible, however, that the effects of radiation likely play the key role here, though, rather than the hormone suppression — further study is needed to determine whether hormone suppression alone can cause shrinkage.

#7 Erectile Dysfunction

Erectile dysfunction (ED) is the inability to get and keep an erection firm enough for sex. While ED isn’t confirmed to be a specific cause of penis shrinking, there are some links between the two to be aware of.

Can I Regain My Penis Size?

The good news is that if you experience penis shrinkage, you can regain your penis size in most cases. Here are a few ways you can regain the size of your penis:

Penile Shrinkage Treatments

Lifestyle Changes

Some causes of your penis shrinking are due to controllable factors like weight gain. This can easily be reversed by making lifestyle changes like devoting yourself to a healthy diet and exercise routine. Once you begin to lose the excess abdominal fat and pubic area fat, you will see your penis begin to resume its normal length as a result of losing the fat bulges.

Temporary Solutions

If your penis shrinks as a result of prostate surgery, the condition may improve within a few months or years. However, there are temporary solutions you can use to help regain your penis length and girth. These solutions include vacuum erection devices or penis pumps, which may help penis shrinkage after prostate cancer treatment.

Erectile Dysfunction Treatments

Treating Erectile Dysfunction or ED may be a viable option for improving erection function if not size. Penile rehabilitation is a form of physical therapy for men struggling with their ability to gain and achieve a solid erection. There are also medications available for ED, like Viagra or Cialis. In addition, Better Body MD offers optimal ED treatments, including the innovative Focused Shockwave Therapy in Northern Virginia and other ED treatments in Virginia. Treatments help increase the blood flow to the penis, helping you achieve an erection. However, they won’t necessarily make your penis bigger. Vacuum therapy and penile traction therapy, if correctly performed, can apply gentle tension to the penile tissues and slowly allow lengthening of the penis.

Penile Enlargement Surgery

If you’re worried about the size of your penis and want to enjoy a more enhanced penis, both flaccid and erect, a Penuma implant can help. This is an excellent treatment for making your penis bigger. Best of all, the Penuma implant is FDA-cleared, safe, effective, and the perfect treatment for increasing your length and girth.
