PRECOCIOUS PUBERTY

The onset "too early" of secondary sexual characteristics such as breast buds in girls, growth of the penis and thinning of the scrotum in boys and the appearance of pubic hair in both sexes. "Too early" is difficult to define because there is so much normal variation. However, precocious puberty is generally the onset of puberty before age 8 years in girls and age 9 years in boys.
