  • Awareness of male hypogonadism is growing, but many adult men with the condition remain undiagnosed and untreated.

  • The alpha subunits of the hormones are identical, whereas the beta subunits are distinct and confer the unique biological and immunological properties and receptor specificity of each of these glycoproteins All confirmed an increase of height velocity without an adverse effect on bone age in boys with CDGP [ 14172184 ].

As a result, their dosing is not very flexible and does not permit easy titration, which is essential for therapy in adolescents. The specific needs of adolescent powt with chronic illnesses and functional hypogonadism should also be addressed. Because these formulations were designed for adults, dosing is not flexible or easily titrated, which is essential for therapy in adolescents, especially to initiate pubertal maturation.
