1. When does the penis begin to grow?
Penile development begins during puberty, the time when a person begins to mature sexually. For those who are sexed male at birth, this process typically begins between the ages of 9 and 14.
Increased testosterone levels in males during puberty cause physical changes including: increased height, increased penis size, and the growth of facial and pubic hair.
The penis begins to grow in length first, followed by its width. This growth is not continuous; it occurs in stages and continues until the end of puberty, usually 2-5 years after it begins.

The penis begins to develop during puberty.
2. What is the average penis size?
Penis size is determined by an individual's genes and hormones. Penis size varies among different population groups.
Several factors influence penis size, including:
Cold temperatures: This condition can make the penis appear smaller than normal.
Genes: Genes can affect hormone levels. Mutations in the SRD5A2 gene can affect hormones that influence male sexual development, including penis size.
Hormones: Studies have shown that androgen levels affect penis development, including length. Androgens are sex hormones present in both men and women, but men typically have higher levels than women.
The following figures represent average penis sizes compiled from various scientific studies:
Length
When standing upright: 5.1 inches (1 inch is approximately 2.54 cm)
When in its soft state: 3.6 inches
Circumference (thickness)
When standing upright: 4.5 inches
When in its soft state: 3.6 inches
To measure penis length, use a tape measure. Begin measuring from the base of the penis and stretch the tape to the tip. To measure circumference, gently wrap the tape around the widest part of the shaft.

Penis size does not affect sexual ability or desire.
3. Is penis size important, and is it possible to increase penis size?
Penis size can affect self-image. Over 50% of men are dissatisfied with their penis size, even though 85% of their partners are satisfied.
In other words, penis size does not affect sexual ability or desire. It only matters whether the man and his partner are satisfied or dissatisfied with it.
Some medical and surgical treatments claim to increase penis size, but scientific evidence is limited.
In summary, penile development typically begins during puberty, between the ages of 9 and 14, and usually stops between the ages of 18 and 21.
Penis size is determined by genetic and hormonal factors. There are some procedures or surgeries that can increase penis size, but these can only be performed by a urologist.
