Why are we Told that Testosterone is Bad?

If Testosterone replacement can make us live longer, decrease insulin resistance and the incidence of diabetes by 44%, decrease the thickness of the intima of arteries (plaque), decrease LDL (the bad one) cholesterol levels, decrease the rate of heart disease, and stroke, suppress inflammation (it decreases cytokine production), reduce the adhesiveness of platelets as well as decreases fibrinogen levels, both of which can cause cause blood clots, is a vasodilator and improves erections in men and vaginal wetness in women, improves cardiac output for those with heart failure, increases muscle mass in both sexes which prevents frailty, decreases the symptoms of Parkinson’s disease by increasing Dopamine, decreases obesity by increasing  lean body mass (muscle), improves our sexual desire and treats depression at the same time, improves our overall immunity and finally decreases mortality from all causes, why does organized medicine and those agencies that serve it (the government, FDA, NIH, Specialty Boards) continue to repeat the cry of caution and fear to men and women when it comes to testosterone?
