[Study on cases of precocious puberty].

Two boys and one girl with idiopathic precocious puberty were treated with medroxyprogesterone acetate (MPA) for 2 years and 2 months to 9 years and 5 months, and its efficiency was evaluated. Treatment with MPA suppressed the gonadotropin levels, the signs and symptoms of patients with precocious puberty, and also had a suppressive effect on bone-age advance, so these patients showed almost normal growth in height. There has been controversy about the age when treatment for idiopathic precocious puberty should be finished. Our data suggested that the treatment should be stopped at 11-13 years when patients reach the age of puberty.
