No. There is no evidence that it can. However, treatment with TRT to restore testosterone levels to normal has been shown to lead to a significant reduction in hospitalisation and mortality from all causes among men with health problems including coronary heart disease, type-2 diabetes and heart failure. TRT can also reverse progression to type-2 diabetes. Since older men with type-2 diabetes are more at risk from Covid-19, in the current context TRT may play a part in general health maintenance and preventive healthcare.
