Could someone send me a list of the Tanner stages of Puberty? I had the list once, but cannot locate it.
    

Once a child reaches an age before puberty begins, growth can be interpreted by a child's pubertal status and sexual development.

There is considerable individual variation as to when puberty begins in children. For example, in girls it can be anytime between ages 8 ½ and 13 years of age ( average 11 years), and in boys puberty occurs between ages 9 ½ years and 13 ½ years (average 11 ½ years). Years ago, a pediatric endocrinologist Dr. Tanner developed stages of sexual developed that are referred to as "Tanner Stages" or Sexual Maturity Ratings (SMR). These "stages" give physicians a way of evaluating a child's sexual development. Parents should remember that while every child develops along the same path to complete sexual development, they do so at different times.

The Tanner Stages were developed by observing the pubic hair of both males and females, the male genital area, and the female breast.

Male Genital

  • Stage 1 testes small in size with childlike penis
  • Stage 2 testes reddened, thinner and larger (1.6-6cc) with childlike penis
  • Stage 3 testes larger (6cc-12cc) and scrotum enlarging. Increase in penile length
  • Stage 4 testes larger (12cc-20cc) with greater enlargment and darkening of the scortum. Increase in length and circumference of penis
  • Stage 5 testes over 20cc with adult scrotum and penis

Female Breast

  • Stage 1 no breast tissue with flat areola
  • Stage 2 breast budding with widening of the areola
  • Stage 3 larger and more elevated breast extending beyond the areola.
  • Stage 4 larger and even more elevated breast. Areola and npple projecting from the breast contous
  • Stage 5 Adult size with nupple projecting above areola

Male and female pubic hair

  • Stage 1 none
  • Stage 2 small amount of long hair at base of male scrotum or female labia majora
  • Stage 3 moderate amount of curly and coarser hair extending outwards
  • Stage 4 resembles adult hair but does not extend to inner surface of thigh
  • Stage 5 adult type and quantity extending to the medical thigh surface
