The endocrine system helps in the development of an individual in childhood, in the adolescent phase, and then in aging in later life.


The pituitary gland is the master gland and controls the production of other hormones. It is controlled by the hypothalamus and helps is regulation of the other hormones. They are responsible for both physical and mental development.


The thyroid gland also helps in development. It helps in the development of the nervous system in an individual. For example, deficiency in the production of thyroid hormone during pregnancy showed symptoms of intellectual disability.


Androgen in males and estrogen and progesterone in females helps in the development of sex organs. The onset of menstruation in females is also due to these hormones. Progesterone helps in conception and pregnancy. Estrogen helps in the development of the reproductive system in females along with the secondary sexual characteristics. Testosterone also helps in the development of the reproductive system but in males along with secondary sexual characteristics.
