Testosterone and DHEA are considered androgens and they play an important role in tissue regeneration, especially the skin, bones, and muscles. The principal androgen in both men and women is DHEA. DHEA levels decline with age, and in some cases, supplementation with DHEA can restore energy, improve immune function, lift depression and improve mental function. Testosterone is involved in maintenance of lean body mass, bone density, skin elasticity, sex drive and cardiovascular health in both sexes.
