I have come across few studies that show metformin can reduce testosterone levels significantly and leads to low sex-drive and ED. I am just wondering anyone taking metformin has observed this affect or tested their testosterone levels before and after metformin therapy? You can Google it and there are few search papers to prove this, but just wanted to see how it affects in real time. I am thinking of starting taking metformin so just weighing my options. I know it reduces B-12 levels as well in long-term.
