Girls do not change into boys during puberty. Girls can only turn into boys if they have a sex change operation and a continuing course of hormone injections.
The main hormone is testosterone in boys. Its estrogen in girls.
Testosterone is the male hormone that controls Puberty and growth in a male. Boys have other hormones in their bodies also, including female hormones ! But Testosterone is the greater male hormone that gives boys their characteristics.
The name of that hormone is testosterone. This hormone is responsible for secondary sex characters in the boys. This hormone makes them aggressive. It is secreted by the endocrine cells from your testes.
Growth hormone helps bone growth. Just sleep to get it. People who are deficient have lower muscle and get tired easily. Visit a doctor if you're deficient. Testosterone and estrogen advance puberty and cause the closure of bones which means that you have stopped growing.

Puberty is apparently triggered by a chemical from the hypothalamus gland, which stimulates the release of hormones by the pituitary gland, which in turn causes sex hormones to be generated in the ovaries (female) or testes (male). Puberty normally occurs between the ages of 10 to 17 for girls, and 12 to 18 for boys. Puberty is the post-adolescent onset of sexual physiology, as the body completes the development of the reproductive system. This includes hormonal changes, as well as associated behavioral attitudes and inclinations. Boys become more interested in girls, and girls in boys. This is the beginning of human adulthood. Changes in the body are not limited to sexual ones, but encompass extensive physical and mental alterations that define gender differences.
