I am a 38-year-old man. For the last few months I have been experiencing a sharp decline in my libido and also in my performance time, i.e. the amount of time I am able to maintain an erection for. I don’t even get regular morning erections anymore. There has been no change in my schedule, lifestyle or diet, and I am not under any unusual amount of work related pressure either. I have been applying MG5 topical solution for hair growth. Could the use of that solution result in these side effects? What medicine can I take so that my libido may recover, and I can go back to having a healthy sex life?
