Like many other body parts, penises come in different sizes and shapes. Most men have penises of between 6 and 13 centimeters when soft (not erect). The penis increases in size until about 19-21 years of age, after this age, the actual size changes only slightly or remains the same.

For some however, it may shrink (get smaller). In this piece we share the explanation for this as shared by Love Matters.

Weight gain

If you gain a lot of weight, your penis may start to look smaller. Note that this does not mean that it actually becomes smaller, it just looks smaller. What really happens is that when the belly expands, it pulls the penis inwards. If you lose weight, the penis will get back to its normal shape and size.

In very obese men, fat can cover most of the penis thus making it hard for a man to see his own penis.

Other body parts may age like fine wine but your penis may not.

As you grow older, you may notice that your penis and testicles become smaller. This happens because as you age, there is reduction in blood flow to the penis. This is, in turn, caused by an increase of fatty deposits in the arteries.

Also, constant small injuries from sex and sports may lead to accumulation of scar tissue in the penis. These scar tissue affect your penis’ erectile tissues leading to shrinkage and affecting erection size.

To maintain erectile function with age, remain physically active, eat a balanced diet, quit smoking, and avoid drinking alcohol excessively.

Peyronie’s disease
Every heard of curved and painful erections?

Peyronie can reduce the length and circumference of your penis. This s because this disease makes the penis to be bent when erect, instead of straight. Men can still have sex but it tends to be painful. This condition can be corrected through surgery.

Those smoking packets with scary images should start including pictures of smaller penises as a warning to smokers. Maybe this will encourage them to stop smoking.

Smoking is bad for your overall health but I bet you did not know it also affects your penis.

The chemicals in cigarettes can affect blood flow to the penis. This is because these chemicals can injure or narrow the blood vessels in the penis thus preventing it (penis) from being filled with blood and stretching.

Smoking has also been associated with erectile dysfunction.
Stop smoking, save your penis!

Prostrate surgery
Most men who have had a cancerous prostrate removed experience a small to moderate decrease in their penis. Some men who undergo this procedure may not experience any shortening at all.

Some medications such as some antidepressants and certain drugs for enlarged prostate have been found to cause penis shrinkage

Now you know.


A slight to moderate reduction on your penis size should not prevent you from having enjoyable sexual experiences. If it is due to other medical conditions such as Peyronie’s disease, visit a doctor for treatment.
