Puberty is a stage of life that puts you on a physical, emotional, and hormonal fast-track to adulthood. In simple terms, your body goes through rapid physical, emotional, and hormonal changes that prepare you for reproduction and childbirth.
Female puberty happens when certain hormonal changes provoke your ovaries to pump out estrogen that prepares your body for reproduction and childbirth. It usually begins between the ages of 8 and 13 and lasts for several years.
