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.

Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

This form of study is generally done to predict the association between the disease and the risk factor.

The prime objective of the study is to predict the exposure of the risk elements for the individuals present in two groups, that is, controls and cases. This form of study is also called case-referent studies or retrospective studies.
