ABSTRACT

Precocious puberty is considered when it begins before seven years of age in the girls and before nine years in boys. Among its causes are: hereditary, cerebral damages, infectious illnesses as the meningitis, thyroid problems, the tumors in the brain and the ovaries. It should be confirmed that it is really a precocious puberty and to discard other causes, to analyze the curve of growth and to request complementary tests. The most common is doll and hand x-ray that allows determining the bone age. An ultrasound of ovaries should also be requested to check its development, an analysis of blood to measure the hormonal concentrations. The different physical changes are stimulated by the androgens and the estrogens, which are regulated at level of the axis hypothalamic-pituitary-gonads. When the precocious puberty is produced by the stimulation of this axis, it is denominated as true or central precocious puberty; but when the axis is not stimulated and the sexual hormones are elevated by some other causes it is denominated pseudopuberty or peripheral puberty. The objective of treatment is to stop or even to revert the sexual development and to break the quick growth and the maturation of the bones. If what causes the precocious puberty is an illness or a tumor, the treatment against the cause (ej extirpation of the tumor) usually stops the process of puberty. Depending on the age and of the speed with the sexual characters are developed, physician will take the decision about administering or not medications to retard the development. When the changes are taking place in a quick way, the treatment should begin immediately. The treatment of the most effective precocious puberty consists on the use of deposit GnRH that stops the production of hormones, it retards the menstruation and allows that the body continues being developed with normality.
