The program explains to viewers that sometimes puberty can be confusing and that it’s normal to have many questions. Students will come to understand the changes they can expect to happen during puberty. In the end, viewers will come to appreciate that puberty is a normal part of growing up, there is no right or wrong schedule for development and the timetable is different for everyone.
Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. Hormonal signals from the brain to the gonads-the ovaries in a girl and the testes in a boy-initiate it. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth-height and weight-accelerates in the first half of puberty and is completed when an adult body has been developed. Until the maturation of their reproductive capabilities, the pre-pubertal physical differences between boys and girls are the external sex organs.
On average, girls begin puberty around ages 10-11 and end puberty around 15-17; boys begin around ages 11-12 and end around 16-17. The major landmark of puberty for females is menarche, the onset of menstruation, which occurs on average between ages 12 and 13. For males, first ejaculation occurs on average at age 13. In the 21st century, the average age at which children, especially girls, reach puberty is lower compared to the 19th century, when it was 15 for girls and 16 for boys. This can be due to any number of factors, including improved nutrition resulting in rapid body growth, increased weight and fat deposition, or exposure to endocrine disruptors such as xenoestrogens, which can at times be due to food consumption or other environmental factors. Puberty which starts earlier than usual is known as precocious puberty, and puberty which starts later than usual is known as delayed puberty.
Notable among the morphologic changes in size, shape, composition, and functioning of the pubertal body, is the development of secondary sex characteristics, the "filling in" of the child's body; from girl to woman, from boy to man. Derived from the Latin puberatum (age of maturity), the word puberty describes the physical changes to sexual maturation, not the psychosocial and cultural maturation denoted by the term adolescent development in Western culture, wherein adolescence is the period of mental transition from childhood to adulthood, which overlaps much of the body's period of puberty.
Two of the most significant differences between puberty in girls and puberty in boys are the age at which it begins, and the major sex steroids involved, the androgens and the estrogens.
Although there is a wide range of normal ages, girls typically begin puberty around ages 10-11 and end puberty around 15-17; boys begin around ages 11-12 and end around 16-17. Girls attain reproductive maturity about four years after the first physical changes of puberty appear. In contrast, boys accelerate more slowly but continue to grow for about six years after the first visible pubertal changes. Any increase in height beyond the post-pubertal age is uncommon.
