Its copper delivery function is biologically significant because copper is a cofactor for lysyl oxidase (essential for collagen cross-linking), superoxide dismutase (antioxidant defense), and cytochrome c oxidase (mitochondrial energy production)

hCG was also shown to upregulate the expression of IGFR in rat Leydig cells suggesting cross-talk between both pathways (90, 103)
