Conclusion : 1. Treating girl with EFP is not justified, esp in final height 2. These girls may benefit from appropriate emotional maturity can adjust more easily to sexual maturity.

Psychosocial aspects of Early puberty Concerning physical differences- withdrawal, depression, internalizing disorders Group menarche before 11 yrs, At age 10 less concentration in school At age 13 to 15 rule breaking at home and school antisocial behavior(taking drug,drinking) normal IQ but school performance sexual debut and 14% abortion hx by age 16 yr At age 25 and 43- no difference in marital status lower educational level and status occupations
Conclusion : To treat or not to treat idiopathic early puberty Girls with puberty before age 6 will benefit from GnRHa treatment in terms of final stature and psychological area Girls with puberty before age 6 and 8 yrs of age will probably benefit in terms of final stature and psychological area Girls with puberty before age 9 will benefit in terms of psychological area. lacking study for boys with precocious puberty

Metformin treatment to prevent early puberty in girls with precocious pubarche JCEM 2006;91:2888-91 Obese girls and low birth weight(lbw) girls with early-normal onset puberty (B2 at 8-9 yr) usually have hyperinsulinemia and hyperlepinemia. Metformin therapy delay in the clinical onset of puberty,ultimately may heighten the short adult stature of LBW-precocious pubarche girls.

Relevant questions to be addressed before initiation of GnRHa therapy in CPP Age at occurrence of pubertal development consistent with precocious or borderline early puberty Clinical,ultrasound, and hormonal findings consistent with of evolving or slow variant form of sexual precocity? Predict adult height within or below target height range? Changes in pubertal development,growth, and predict adult height during a follow up of 6-12 months? At borderline ages, remaining psychological problems? Lebrethon 등 Curr Opinion in Ped 2000;12:394-399
