For most men, penis size is a matter of real concern. They believe that a larger penis size is the ultimate way to give sexual satisfaction to their partners. However, most men do not have any idea when the penis size stops growing.

We will discuss this matter in detail in this blog post. We will tell you about lots of other important information as well, such as the average size of the penis for adult males when it is flaccid or erect, and whether size matters or not.

Make sure to sight tightly and read this post right until the end, as we will break many myths surrounding the penis length, its size here. So let us start our journey.


When Does Penis Size Stop Growing?


As per research, it has been found that penis size stops growing after a certain age. When scientists studied the matter in detail, they found that it usually stops to grow any more after adulthood.

However, when you hear the term adulthood, it may not signify a particular age. One study done at the National Institute of Health suggests that men may notice a growth in their penis size up to the age of 20s.

The size of your penis only begins to see a rapid growth during the time of puberty, which sets off within the age of 10 years and continues until you are about 14 to 15.

PENIS

This is the time when your penis size grows faster than ever. Scientists believe that it is a function of the testosterone hormone, which also peaks during puberty in males.

More in-depth studies show that during this age in boys, the penis can grow at an average rate of half an inch every year. However, by the end of puberty, the penis size growth rate begins to see a drop.

Scientists noted that the penis size could still increase even after puberty has passed in males. It continues to grow but at a slower rate, usually until the time you reach your teenage years, that is, 18 to 20 years in males.


The Average Penis Length For Adults


The length of your penis may differ greatly. Scientists believe that there are many factors that may determine the average adult size penis. This may include.

  • Genetic factors
  • Race
  • Cast
  • Ethnicity
  • Hormones
  • Health

However, through many studies, scientists have been able to get a rough estimate. As per the studies, it has been found that the average flaccid penis size will be at around 3 to 4 inches.

Of course, there is an increase in your penis size when you get an erection. Your penis may see a growth of 2 inches when it is fully erect. This means that the standard penis erect size in males is around 5 to 6 inches.


Making Your Penis Size Bigger


To make your penis size bigger, there are many techniques, such as the use of topical creams, lotions, and even surgeries. Let us talk about some of the ways in brief-

⮞ Use Of Topical Lotions And Gels

Many non-prescription creams and gels claim to increase your penis size. If you talk about scientific evidence of actual work about these creams, there is no validity. This means that even if someone may have seen a growth in the penis size after adulthood, the same may not be true in your case.

Make sure to validate such claims made by these products with the help of a doctor before using them directly, as they can cause side effects as well.

⮞ Surgeries For Increasing Penis Size

Some people are so concerned and egoistic about their small penis size that they would take up any method to increase their size. One of the costly, although common ways to increase the penis size is with the help of surgery.

However, what most people miss is the fact that such surgeries do not help you to increase the size of an erect penis, as it remains the same. The objective of these surgeries is to make your penis size look bigger when it is normal in a flaccid or unexcited state.

⮞ Use Of Supplements

There is, of course, a range of supplements, some even claiming to be made with natural ingredients that help you to increase penis size. Again, there is a need to verify the claims from a doctor before trying out such products.

⮞ Use Of Vacuum Pumps To Increase Your Penis Size

So, what if your penis size is smaller? There is a way that you can still erect your penis hard and strong and maintain an erection. Use of vacuum devices only helps you to get an erection, though.

There is no such ability that they can increase your flaccid penis size, however. Most doctors recommend the use of such penile pumps and vacuum devices during ED when they have lost the ability to get a strong and hard erection.


Does Penis Size Even Matter- A Fact Check And Bursting Common Myths?


Even though males think that women consider masculinity and attraction to the penis size, it is not always the case. As per a review study in 2006 from the Psychology of Men and Masculinity, it has been found that it is men who are more concerned about their penis size than their partners are.

As per this study done on women, a majority, close to about 85% feel that it is not always the penis size that can bring greater satisfaction. Females believe it is the ability to insert the penis at the G-spot to give them sexual satisfaction that matters.


Final Thoughts


Therefore, as you can see, the penis size in adults usually stops growing by the age of 18 to 20 years of age in males. The most drastic penis size increase is seen in the time of puberty in boys, where the penis attains its 75% size that lasts a lifetime.
