Premature adrenarche is the most common cause of premature pubarche. Rarer causes include precocious puberty , congenital adrenal hyperplasia , and androgen producing tumors of the adrenals or gonad s. When adrenarche, central puberty, and all pathologic conditions have been excluded, the term isolated premature pubarche is used to describe the unexplained development of pubic hair at an early age without other hormonal or physical changes of puberty.

- Delayed puberty
Infobox disease Name Delayed puberty ICD10 ICD10 E 30 0 e 20 ICD9 ICD9 259.0 DiseasesDB 17462 MeshID D011628 Puberty is described as delayed puberty with exceptions when a boy or girl has passed the usual age of onset of puberty with no physical or hormone 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 malnutrition undernutrition , many forms of systemic disease , or to defects of the reproductive system hypogonadism or the body s responsiveness to sex hormone s. Normal timing Globalize date December 2010 Approximate mean ages for the onset of various pubertal changes are as follows. Ages in parentheses are the approximate 3rd and 97th percentiles for attainment. For example, less than 3 of girls have not yet achieved thelarche by 13 years of age. Developmental changes during puberty in girls occur over a period of 3 5 years, usually between 10 and 15 years of age. They include the occurrence of secondary characteristics beginning with breast development, the adolescent growth spurt, the onset of menarche which does not correspond to the end of puberty and the acquisition of fertility , as well as profound psychological modifications. The normal variation in the age at which adolescent changes occur is so wide that puberty cannot be considered to be pathologically delayed until the menarche has failed to occur by the age of 18 or testicular development by the age of 20. class wikitable For North American, Indo Iranian India, Iran and European girls For North American, Indo Iranian India, Iran and European boys Thelarche 10.0y5m 8y 13y Pubarche pubic hair 11y 8.5 13.5y Growth spurt 11.25y 10 12.5y Menarche 12.5y 10.5 14.5y Adult height reached 15.5y ? ?y Gonadarche testicular enlargement 11.5y 9.5 13.5y Pubarche pubic hair 12y 10 14y Growth spurt 14y ? ?y Completion of growth ... more details
