Once puberty ends, there is unlikely to be any further 4-5 growth.
That said, some males may experience growth into their early 20s.
Many males have concerns about the size of their penis at some point.
However, Medical News Today research has shown that most men have a 4-5 size that is within the normal ranges.
For boys, puberty generally occurs between the ages of 12 and 16.
It can begin at any point between the ages of 8 and 14 and may last for up to 4 years.
During this time, the 4-5 will get longer and thicker. The rate at which growth occurs varies from one person to another.
Once puberty ends, then the 4-5 will stop growing. This is typically by the time the male reaches 18 years of age.
Other changes that affect the penis and genitals during puberty include:
Testicle growth
Thinning and reddening of the testicles
Pubic hair growth around the penis
Nocturnal emissions of semen, or "wet dreams"
More frequent erections and ejaculation
Research on 15,521 people from around the world reports that the average penis length is 9.16 centimeters (cm), or 3.61 inches ("), when sleeping and 13.12 cm, or 5.16", when it is awake.
The average girth, or circumference, is: 9.31 cm, or 3.67", when sleeping
11.66 cm, or 4.59", when it is awake.
Studies show that most males who believe they have a short penis overestimate the average penis length. The majority of these people are actually within the normal ranges of penis size.
