Updated: Jul 1

It's no secret that our society is obsessed with size, whether it's the size of a person's waistline, their bank account, or, in this case, their penis. While it's true that the size of a person's penis can influence their confidence during sex, it's also important to keep things in perspective. The average penis size is relatively modest, measuring in at around 5.1 - 5.5 inches when erect.

So if you're concerned that your penis falls on the smaller side of things, know that you actually may be in the majority and you just didn't realize it. Penis size is a topic of concern for many men, and there is a lot of misinformation out there about how age affects penis growth.

Which is why we will be discussing it today... what your penis growth with age looks like... what causes a decrease in size .... and how you can prevent it.

Keep in mind that everyone is different, and these are general guidelines and information about penis growth with age. We're here more to provide you with as much information about the stages of penile growth so that you can apply it to you're life and experiences.

What Is An Average Penis Size (Length and Girth)?

In a study published in the National Library of Medicine, researchers surveyed a group of 200 men about their concerns regarding body image, including their penis size. Around 68% of the men said they had some level of concern and had negative thoughts about themselves in this area.

It's no secret that society has a preoccupation with penis size. From locker room banter to late-night jokes, it seems like everyone is fixated on how big or small someone's member might be.

An erect penis has an average size of 5.16 inches (13.12cm). The average girth is 3.66 inches (9.31cm). These numbers come from a study of 15,521 men who were measured by health professionals in 2014.

Lastly, from a thorough guide on penis sizes, CalsSD provides some great research and insight on the matter. According to their studies, the average penis size is 5.49 in length and 4.58 inches in girth when erect. The average flaccid penis is 3.54 inches long and 3.52 inches in girth. In addition to the studies they reviewed, they have a penis size calculator that compares sizes against a group of a thousand guys.

The Average Penis Size & Shape Changes with Age

Just as your body changes with age, so does your penis. In general, erections become less frequent and don’t last as long after a certain time. Impotence is linked to aging. In a study conducted in Turkey, the percentage of men who suffer from erectile dysfunction rises quite a bit once they reach their 50s.

The mean age of a total of 2,760 males who completed the survey was 54.2±10.6 years. Below shows you the number of males who suffered from ED based on age groups.

40-49 Years


50-59 Years


60-69 Years


70+ Years


Although there is a direct correlation between your age and developing some sort of erectile dysfunction, that doesn’t mean your penis will stop growing in size. The penis grows the most during puberty, usually between the ages of 9 and 18. During this time, boys will experience a growth spurt in both height and weight. As the body grows, so does the penis.

The size of a man’s penis is largely determined by his genetics, but other factors, such as weight and hormones, can also influence its size.

The majority of males will have reached their full adult penis size by 18 years old. Now there are some cases where some men still grow until they’re 21 or 22, but it depends on when they started puberty. If you’re in this category, then you’re considered a “late bloomer”. After that, your penis is very unlikely to naturally continue to grow.

What Controls Penile Growth & the Lifecycle of Your Penis Size

To give you a simple idea of the lifecycle of your penis size and how it changes, here is a simple look:

Age 9-15

Your pituitary gland begins to release hormones and your body starts to make testosterone. This allows you to grow your testicles, scrotum, penis, and public hair.

Age 20-22

Your testosterone levels will peak and you've reached the high point for your hormones, testosterone, and penile growth.

Age 22-40

Your testosterone levels can experience a slight drop, however, there won't normally be any huge changes

Age 40+

Testosterone levels can experience another drop in levels and your body will begin to create binding globulin, another hormone. This hormone will stick to your testosterone and will lower the amount your body will have available.

Changes to Your Penis After 40

After the age of 40, there are a number of things that can happen to your body downstairs... let's take a look and see what happens to you and your penis with age.

Pubic Hair

Your pubic hair will most likely begin to thin out and lose its color, much like the rest of the hair on your head.

Penis Size

As we already touched on earlier, you're not going to see any huge changes in your penis size after 40. However, erectile dysfunction is much more prevalent once you reach 50.

Penis Shape

The shape of your penis isn't likely to make any huge changes either. However, you can develop a curve in some men. Peyronie's disease can be caused by a physical trauma in your life. This is the physical injury of your shaft (usually due to sex) where it gets bent. When the scar tissues heal, they can form in a curvature.

Your Testicles

Your testicles are likely to shrink as you get older. This is due to the fact that they are what allows you to create sperm. When your testosterone begins to slow down, your sperm production will also slow down... which results in your balls shrinking.

The Scrotum

As you age, you being to lose muscle and your skin begins to sag. The scrotum is a muscle that helps with your testicles. As you age, you'll likely see them begin to sag along with the rest of your skin and muscles.

Penile Sensitivity

Is also common for men to experience loss of penile sensitivity with age. It can take more time and stimulation for you to get aroused. It's important to know about Death Grip Syndrome. This can happen from slowly tightening your grip during masturbation too much over a long period of time. Which can lead to ED!

Penis Function & Erectile Dysfunction

There are quite a bit of different ways that someone can develop ED and your chances of developing it will increase as you begin to age as we already mentioned. Whether that is through bad lifestyle choices, low testosterone levels, diseases such as Peroniyes or Diabetes, your likely hood will be higher.

Acceleration of Penis Size with Age

It's no secret that penis size and your penis aging can be a sensitive topic for many men. Which is ok and why we are discussing it today. And like we mentioned before, while genetics plays a role in penis size, there are several other factors that can also affect it that you should know about.

Here are a few things to keep in mind that can have a negative effect on your penis size over time:

Obesity: Obesity can lead to diabetes, which can be directly correlated with erectile dysfunction

Exercise: Your body requires you to stay active in order to stay healthy and if you don't, it can have quite a few negative effects on you... one of which can be ED

Smoking: Smoking not only leads to cancer, but it can also have an effect on your penis over time.

Stress: Believe it or not, stress can have an effect on your penis as well. Having and maintaining an erection is not just physical, it's mental as well. If you're not in a healthy mental state, you can have issues with erections.

Alcohol: Consuming too much alcohol is also bad for your penis and erections. Over time over consumption can lead to ED.

These are all things to be aware of and to start taking care of now, especially if you are under the age of 40. These most likely won't be a problem today or tomorrow, but over a long period of time, these are going to be a serious issue for your penile health. So start caring for your health today... you'll thank yourself later in life!
