Low Testosterone after taking Metformin?

Metformin is very bad for men. Not only does it reduce(flatline) testosterone but it impairs penile sensitivity. There is a reason it is prescribed by doctors to increase breast feeding response and reduce testosterone in females. What do you think it does to men? Expect 1-3 MONTHS to recover from Metformin Penile Disfunction with proper supplements and detoxing. Doctors don't tell people this and instead just say ED is a 'part of growing old' then they prescribe something for that!
