DIAGNÓSTICO DIFERENCIAL ENTRE HIPOGONADISMO HIPOGONADOTRÓFICO Y RETRASO PUBERAL SIMPLE EN VARONES CON NIVELES BASALES DE FSH

Niveles basales de FSH < 1.2 UI/l confirman el diagnóstico de hipogonadismo hipogonadotrófico, sin necesidad de otra prueba diagnóstica, en varones con pubertad ausente o incompleta. En casos de niveles de FSH > 1.2 UI/l, el valor pico de FSH y LH luego de una infusión de GnRH tiene alta exactitud diagnóstica.
