Estrogens, growth hormones and IGFs are essential in the development and growth of the skeleton and for the maintenance of bone mass and density. Treatment of precocious puberty with gonadotropin-releasing hormone analogs (GnRHa), leads to a situation of hypoestrogenism by reducing sex-steroid levels, which, theoretically, may have a detrimental effect on bone mass during pubertal development. A reduction in bone mineral density during GnRHa treatment has been shown, but GnRHa treatment in patients with central precocious puberty does not seem to impair the achievement of normal peak bone mass at adult height. However, calcium supplementation is effective in improving bone densitometric levels and may promote better peak bone mass achievement.

Abstract
Estrogens, growth hormones and IGFs are essential in the development and growth of the skeleton and for the maintenance of bone mass and density. Treatment of precocious puberty with gonadotropin-releasing hormone analogs (GnRHa), leads to a situation of hypoestrogenism by reducing sex-steroid levels, which, theoretically, may have a detrimental effect on bone mass during pubertal development. A reduction in bone mineral density during GnRHa treatment has been shown, but GnRHa treatment in patients with central precocious puberty does not seem to impair the achievement of normal peak bone mass at adult height. However, calcium supplementation is effective in improving bone densitometric levels and may promote better peak bone mass achievement.
