The teenage years are also called adolescence. During this time, teens will see the greatest amount of growth in height and weight. Adolescence is a time for growth spurts and puberty changes. A teenager may grow several inches in several months followed by a period of very slow growth. Then they may have another growth spurt. Changes with puberty may happen slowly. Or several changes may occur at the same time. It's important to remember that these changes will happen differently for each teen. Some teens may experience these signs of maturity sooner or later than others. And being smaller or bigger than other boys is normal.

As an adult, you probably remember puberty — a time when your body went through a lot of changes. Professor James M. Tanner , a child development expert, was the first to identify the visible stages of puberty. Today, these stages are known as the Tanner stages or, more appropriately, sexual maturity ratings. They serve as a general guide to physical development, although each person has a different puberty timetable. Read on to learn about the Tanner stages and what you can expect to see in boys and girls during each stage. Toward the end of stage 1, the brain is just starting to send signals to the body to prepare for changes. The hypothalamus begins to release gonadotropin-releasing hormone GnRH.
What does my adolescent understand?
Each of the 20 age groups age range, years had an equal number of males ie, However, both penile and testicular development demonstrated peak growth from 12 to 16 years of age, which coincided with the maximal male pubertal growth spurt. Data indicate an earlier pubertal development for this study population than that for a similar population several decades ago. Significant differences between urban and rural populations regarding penile length were also noticed. Our data show that, even by the end of 20th century, there is still some acceleration of male pubertal development. For the first time are reported somatic differences in genitalia within a population between urban and rural representatives. Assessment of growth of external genitalia is an essential component of health surveillance in pediatric and adolescent populations. Because of rapid changes and great interindividual differences at the time of puberty, a universal reference range of hormone values cannot be established at this period of life. Therefore, anthropometric data are quite useful for clinical evaluation and prognosis.
Puberty is the period of human development during which physical growth and sexual maturity occurs. The word puberty is derived from the Latin pubertas , which means adulthood. Puberty is initiated by hormonal changes triggered by a part of the brain called the hypothalamus, which stimulates the pituitary gland, which in turn activates other glands as well. These changes begin about a year before any of their results are visible. Both the male reproductive hormone testosterone and female hormone estrogen are present in children of both sexes.
