Does Average Penis Girth Decrease with Age?

Like the rest of your body parts, your penis is going to change with age. Just as the face you see in the mirror today will not be the same you see in twenty years, the penis you have now will not be untouched by time either. 

This includes your penis length, girth, physical appearance, and health. The good news is that nothing is written in stone, and you can take steps to avoid many of the changes you don’t want to see. 

Are you curious about the changes you can make to increase your average penis girth as you age? Let’s dive in. 

Can Penis Size Change With Age?

The simple answer is yes.

Penis girth varies from individual to individual, but it can also change in size throughout the aging process. 

As you age, reduced blood flow and hormonal fluctuations can change the firmness and elasticity of your penile tissue. This means your girth may also become smaller as well.

This change in size usually isn’t dramatic but may be noticeable over time.

Other Causes of Penis Size Change

Your penis will grow during puberty in both length and girth. Once you reach adulthood, that typically stops.

During adulthood, it should remain the same for most of your life. However, some circumstances such as weight changes, changes in muscle, and shifts in body composition can affect your penis size as well.


Along with lots of other health issues, smoking can cause erectile dysfunction and even penis shrinkage.

Nicotine and other chemicals in cigarettes can constrict blood vessels. This compression lowers blood flow through the penis. Over time, the penis stops enlarging to its fullest potential and gets shorter. 


Some medications that affect blood flow or testosterone can affect the visual size of your penis. For example, a medication used to treat an enlarged prostate is known to cause penis shrinkage.

Fat Loss or Gain

Many men report their penis is bigger after losing weight around their belly. However, this is only partially true. When men have more fat on their stomach and pelvic area, some of their penis can be hidden. Losing weight reveals more of the penis, making it visually appear bigger. Even if there is no real change in size, this can make a big difference for many men. 

Average Penis Size

Studies state that the average penis size for the length of a flaccid penis is 3.6 inches. When erect, the average length of a penis is just over 5 inches.

However, there is a difference between the length of your penis and the girth of it. Girth is the distance around the penis. The average girth size of a penis is 4.5 inches while the average for a flaccid penis is 3.6.

Common Misconceptions About Penis Size

Since penis size plays such a huge role in popular culture, there are lots of myths and common misconceptions you have likely heard. Here are some common myths debunked.

Flaccid Length vs. Erect Length

Many people believe that the flaccid length of your penis always correlates to the erect penis length. This is not true!

Some men are “growers,” which is when their penises are smaller when flaccid but grow considerably larger when erect. Others are “showers,” which means that what you see flaccid is what you get erect.

Shoe Size Correlates to Penis Size

You’ve probably heard that shoe size or the size of your hands correlates to your penis size. The bigger your feet or your hands, the bigger your penis.

This couldn’t be further from the truth! There is actually no scientific evidence of the correlation
