The penis can grow on its own (without external help) until the age of 22 in 87% of men. Except for people who suffer from having a "micropenis", in which case the growth of the penis rather stops soon or it is non-existent.
However, according to my experience and to medical studies, both normal penises and micropenis can be enlarged thanks to exercise stimulation.
You may wonder “can you really enlarge your penis after 22?” I did my research and discovered the medical studies that show we can. Read on to learn more about this answer and at what age it is normal for your penis to stop growing.
When does the penis stop growing?
The penis, like the human being, has an age of growth (based on height) and this usually begins in pubertyand ends at the end of it; in the same way is the height of the man, who although it starts from birth, ends up reaching 21-22 years. The penis has the peculiarity of growing up under erection, so it is very difficult to notice a change in height outside of this state. There are people with the peculiarity of enjoying a few more years of growth; however, others are not that lucky. However, although the penis can grow on its own until the age of 22, thanks to penis enlargement exercises or jelqings, penis growth can be kept active indefinitely.
People with "micropenis" problems see penile growth as non-existent in their organism, as it suffers from certain genetic problems that prevent natural growth. In some men (maximum 12%) the development of the penis ends a few years after initiating or never initiates, giving an average total growth between 1.9 - 2.3 inches (5 - 6 cm); and leaving penises of sizes considered between 2.7 - 3.5 inches (7-9 cm); these can cause problems of many types that go from "health problems" to the typical problems of sexual intercourse and dissatisfaction incapacity.
As a result, the penis size reaches a point of closure at age 19 and 22, while in some men it is reduced to age 15 and 17. The average of inchers/millimetres growth per year is totally relative; however, estimation fixes this growth on at least 0.19 inches or 0.5 cm per year. It is possible that there may be variations such as those with growth problems in the penis where the estimated growth is usually up to 12 years or end in the same way at 22.
