Male enhancement product without birth defect problem

Patient: Dear doctor,I am not interested in sex these days. I had tested my steroids level in local hospital, and the result was OK.In this case, I decide to use some male enhancement products. My wife and i are planning to have baby, and i found some male enhancement product will cause reproductive harm or birth defect(According to Cal prop65).I will really need you help to suggest some male enhancement produce with side effect of birth defect problem. Could you suggest some names of such drugs? Many thanks!
