The changes that occur during puberty are mostly a result of changes in hormone levels in the body.
<h3>Puberty</h3>
The transition from a child to an adult is caused by changes in the level of some hormones in the body.
In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.
In males, there is an increase in the production of testosterone hormone among many other hormones.
