hello there. if you have had your sperm count done and the reports show a decreased sperm counts, then the cause needs to be evaluated. if you are saying based on what you see. then all you need to do is to take very nutritious foods, have lots of water and abstain from masturbation for a few days. it will come back to normal in a few days by itself. also, for another part of your question, I don't feel it will cause any infertility issues. regards
