The Answer is The answer should include the following information: Boys and girls undergo many physical changes when they go through puberty during adolescence. The first change for girls is acceleration in growth rate. It begins around age 10 and ends when girls reach their full height at about the age of 15 1/2 years. Boys typically experience a similar growth spurt at about 12 years of age and reach their full height at around 17 1/2 years. The growth spurts signal the onset of puberty, which involves the bodily changes associated with sexual maturity. One change is the development of primary sex characteristics, which are body structures directly involved in reproduction. For example, girls experience the onset of menstruation, and boys experience the enlargement of the testes, scrotum, and penis and the emergence of the capacity for ejaculation. Another change is the development of secondary sex characteristics, which are body structures that change dramatically with sexual maturity but are not directly involved in reproduction. For example, in girls, the breasts enlarge and the hips widen. In boys, facial hair appears and the voice lowers (girls' voices lower too).
