Delayed puberty

Puberty is described as delayed when a boy or girl has passed the usual age of onset of puberty with no physical or hormonal signs that it is beginning.

Puberty may be delayed for several years and still occur normally, in which case it is considered constitutional delay, a variation of healthy physical development.

Delay of puberty may also occur due to undernutrition, many forms of systemic disease, or to defects of the reproductive system (hypogonadism) or the body's responsiveness to sex hormones.
