Havent yet tried the Clomid for increasing my low testosterone as Im having difficulty finding a doctor in Toronto Canada who is willing to prescribe it. That said I do want to share with anyone else going through a similar experience that I spent two months thinking I had gone completely impotent from taking Risperidone and then Invega only to find myself completely functional when I got intimate with a lady friend recently. The low testosterone caused by these antipsychotic medications simply means I need more of a stimulus to get erect. So dont think that a catastrophe is what you are faced with. There is even a cure I beleive with Clomid - if you can get your hands on it. Androxal will soon be available and that will make it easier to get Clomiphene citrate prescribed for men.
