A Lot More Obvious Body Changes (often ages 13 - 14)




Puberty is a normal part of development where your body starts to change from a kid to an adult. The purpose of puberty is to prepare the body for reproduction. The body changes that occur during puberty don’t happen overnight. Instead, they take years and occur in stages. People call these stages the Tanner Stages or the Sexual Maturity Rating and they are divided into five (5) stages. The stages of puberty typically start around age 8-10 and can last for 5-7 years, however, everyone develops differently and at their own pace. Some may enter puberty earlier than others and some may go through the stages faster.

During this stage, many teenagers notice:

  • Thicker pubic hair – pubic hair can grow more curly and coarse.
  • For most females assigned at birth:
    • Their first period (menarche) occurs between the ages of 12 and 14, although some get it much earlier.  Clear or white vaginal discharge may appear up to 6 months prior to getting the first period.
    • Breasts getting fuller
  • For most males assigned at birth:
    • Their penis, scrotum, and testicles getting bigger and the scrotum sac becoming darker in color
    • A deeper voice becoming more apparent
    • Acne may be appearing due to sebaceous glands under the skin becoming more active and pores in the skin getting clogged, leading to acne.
    • Noticeable armpit hair growing
