Abstract
A girl’s late childhood and early teens are years of rapid physical changes. Between ages 10 and 15, girls grow approximately 25 cm, gain an average of 25 kg, and develop all of the secondary sexual characteristics of physiologically adult women, including the capacity to reproduce. However, while most 15-year-old girls are physically mature, the majority still are not emotionally, cognitively, and socially mature. The physical maturational changes of early adolescence are followed in the midteenage years by dramatic changes in behavior. Girls 15 to 18 often begin to explore their newly acquired sexuality; dating, petting, and sexual intercourse usually first occur in this age group. The relative psychologic and cognitive immaturity at this stage of mid-adoloscence contributes to the high frequency of medical problems that result from sexual behavior.
