Whats penis size by age 12 to 19?

Human penis size
As a general rule, an animal's penis is proportional to its body size, but this varies greatly between species — even between closely related species. For example, an developed gorilla's erect penis is about 4 cm (1.5 in) in length; an fully developed chimpanzee, significantly smaller (in body size) than a gorilla, has a penis size nearly double that of the gorilla. In comparison, the human penis is larger than that of any other primate, both in proportion to body size and contained by absolute lingo.

While results vary across studies, the consensus is that the average human penis is approximately 12.7-15 cm (5-5.9 in) in length and 12.3 cm (4.85 in) in circumference when fully erect. The average penis size is slightly larger than the median size. Most of these studies be performed on subjects of primarily European descent; worldwide averages may come and go.

A research project, summarizing dozens of published studies conducted by physicians of different nationalities, shows that worldwide, erect-penis size averages come and go between 9.6 cm (3.7 in) and 16 cm (6.2 in). It has be suggested that this difference is caused not one and only by genetics, but also by environmental factor such as culture, diet, chemical/pollution exposure[4][5], etc.

As with any other bodily attribute, the length and girth of the penis can be significantly variable between individuals of one and the same species. In many animals, especially mammals, the size of a flaccid penis is much smaller than its erect size. In humans and some other species, flaccid vs. erect penis size vary greatly between individuals, such that penis size when flaccid is not a reliable predictor of size when erect.

Except for extreme cases at either finish off of the size spectrum, penis size does not correspond strongly to reproductive ability surrounded by almost any species.
