The duration of puberty can vary widely, from 1.5 to 6 years in girls and 2 to 5 years in boys. The other statements are false. Menarche typically occurs around age 12 in the United States and many other countries, but there is variation, and some girls may begin menstruation as early as age 8 or as late as age 16. Adolescents who begin puberty early do not necessarily complete it early, and those who begin earlier may actually end up being shorter adults than those who begin later in adolescence.
