[The abnormalities of pubertal development: a review of treatment for them].

Precocious puberty has been defined as the development of secondary sex characteristics before 8 years of age in girls. In the past, therapy with progestational agents, such as medroxyprogesterone acetate or cyproterone acetate had been used. The gonadotropine releasing hormone agonist has been used widely. The ethiologies of delayed sexual development are numerous. A series of 191 patients with delayed pubertal development is reported in this study. Gonadal dysgenesis is 39/119(32.8%), physiologic delay is 27/119(22.7%), Rokitansky syndrome is 17/119(14.3%), hyperprolactinemia is 11/119(9.2%). The girls with physiological delay, hyperprolactinemia or poly cystic ovary syndrome, have subsequent normal reproductive potential. In the treatment of abnormal pubertal development, the individual treatment is important.
