    During puberty, physical changes occur as the child moves into adulthood and becomes capable of reproduction. It is a monumental transition in the human lifecycle. The gonads (ovaries in girls and testes in boys) mature and release sex hormones, leading to important changes in the skin, brain, muscles, bones, and sex organs.

    Puberty is the stage during which adolescents achieve fertility, meaning they are able to reproduce. For young girls, the achievement of fertility is marked by the first menstrual period. At this point, the girl's ovaries begin to produce and release eggs. If the young girl were to have intercourse, her eggs could potentially be fertilized by male sperm, and she could become pregnancy.

    Adolescent boys also achieve fertility and begin producing sperm during puberty. However, there is not a specific point, like menarche for girls, when this occurs.

    While adolescents reach physical maturity during adolescence, emotional and intellectual maturity often lag behind. Sexual education prior to achieving fertility can help adolescence understand the consequences associated with their choices.

    Young boys experience testicular growth followed by pubic hair growth. Around age 11, the penis begins to enlarge, and they may have short term breast growth. Their voices begin to break, and they increase in height. Between ages 14 and 15, auxiliary hair develops, nocturnal emissions begin, and their voices mature. Facial hair tends to be the final stage in male puberty.

    Disordered pubertal development includes precocious puberty, or early onset puberty, and delayed puberty.

    Girls who begin puberty prior to eight years old and boys who begin puberty prior to nine years old exhibit true precocious puberty. To diagnose, doctors determine the maturity of the bones by taking an x-ray of the individual's hand. Blood hormone tests, ultrasound, CT scans, or an MRI may be necessary if the individual exhibits advanced bone age.

    Delayed puberty is diagnosed when girls exhibit no pubertal development by age thirteen or age fourteen in boys. Doctors will evaluate using the individual's medical record looking for signs of chronic disease or hormone level deficiencies. A CT scan, MRI, or chromosomal analysis may be performed. Doctors may often choose to monitor the situation with regular check-ups every six months.

    During puberty, the body undergoes numerous changes as adolescents develop secondary sex characteristics and eventually achieve fertility.

    For young girls, menstruation is one of the milestones of puberty, marking the beginning of fertility. Girls often grow taller and slimmer, and develop rounder hips during this period. Their breasts develop, and hair begins to grow in the pubic area, on the legs, and under arms. Puberty begins for girl before boys, often causing them to appear older than their male counterparts during this timeframe.

    Young boys experience testicle and penis growth accompanied by nighttime ejaculations called "wet dreams." They too have an increase in hair growth and height. Their voices deepen and, usually at the end stages of puberty, boys begin to develop facial hair.

    Both sexes experience increased hormone production that causes sweaty armpits, acne, and body odor.
