Puberty is the period in human development when a child gradually changes into an adult, during which physical growth and sexual maturation occurs.[1]

Start of puberty

Puberty begins when the hypothalumus, which is part of the brain, produces a hormone that stimulates the pituitary gland, which then produces hormones called gonadotrophins that stimulate the gonads and adrenals. Gonads are the testes in males and the ovaries in females. The gonads then produce a flood of sexual hormones that stimulate growth and development of the sexual organs in both genders and in the breasts of females.

Females usually start puberty at about 10.5 years of age, and males start about a year later.[2]

Precocious puberty

Puberty sometimes starts early. When it does, it is called precocious puberty. Puberty that starts before eight years in girls and nine years in boys is considered to be precocious puberty.[2]

Onset of sexual function

Menstruation usually occurs at about 12.5 years of age, while first ejaculation usually occurs at about 13 years of age.

If a foreskinned boy's foreskin has not become retractable prior to puberty, then it will almost certainly become retractable during puberty.[3] [4] [5]

Tanner stages

Dr James Mourilyan Tanner, a British paediatric endocrinologist, created Tanner stages, which describe the progress of puberty through five stages.[2] [6]

End of puberty

Puberty typically lasts for 2 to 5 years. It usually ends for girls at age 15 to 17, and for boys at age 16 to 17.[2]
