Effect of human chorionic gonadotropin on growth velocity and biological growth parameters in adolescents with thalassaemia major

Abstract
The effect of long-term human chorionic gonadotropin (HCG) therapy on the linear growth and biological growth parameters was studied in six thalassaemic boys aged 14.5–15.5 years old with hypogonadotropic hypogonadism. A significant (PPPPPP<0.001) lower than in normal prepubertal children. This study suggests that in thalassaemia major an impaired GH-RH release can be observed, in addition to the described alteration in Sm-C generation.
