Are there any ways t,o improve testosterone level which have been proven to be effective? My husband has tried Androgel, penis injections and prostate massages, all with mininal and temporary effects. He suffers from Diabetes 2 and is obese. He is 61 years old, with a bright mind and not ready to be w/o sex just because he is a senior citizen . Thank you! Sorry, i thought an initial answer end be free.
