Hello pal, get back on propecia. That's the brand name of the finestride. Yes it does decrease a bit of libido in a lot of men from my research. I take it & it affects me a tiny bit but I can definitely perform. I only take it every other day though as a precaution. As for mino, it makes the scalp slightly red & I found it annoying to apply, causes white flakes & itches a bit. I didn't see improvement, so I stopped using it.
My friend suffered problems in the trouser's department with propecia, but he finds mino effective. But at the same time, it caused small bumps on his forehead.
Ask a hair surgeon for advise & to look at your scalp & sides. A general doctor won't be the right person for advise, or at least that's what I found when I asked 3 GPs. Send some pics of your scalp & sides and a lot of ppl here will point you in the right direction.
