Further progress of the etiology,diagnosis and treatment of peripheral precocious puberty / 中华预防医学杂志

ABSTRACT

Peripheral precocious puberty(PPP),also known as puberty independent from hypothalamic-pituitary axis activation,is stimulated by hormones from other sources, with only partial sexual characteristics development but without mature sexual function. The secondary sexual characteristics development occurs before 7.5 years of age in girls and before 9 years of age in boys. Clinical manifestations are diverse, and PPP has varied etiology including congenital adrenal hyperplasia, McCune-Albright syndrome, ovarian cyst, adrenal tumor, ovarian tumor, testicular tumor, human chorionic gonadotropin producing tumor, familial male precocious puberty, aromatase excess syndrome, and environmental estrogen. Early identification of etiology, accurate differential diagnosis and prenatal gene screening play a significant role in the prevention, diagnosis and treatment of the disease.
