My sperm count is low and it looks watery but previously when I begin masturbation as a habit at that time everything was normal and my sperm count also look healthy and milky in color but as the time passed my sperm count is became low in concentration anf it's became watery in color. My height is 6.0 and my weight is 65 kg and my blood group is B+. What is the cause behind my problem and what things should I do to get the solution and have healthy sperm count. I have also following questions in my mind, 1) does this will effect on my future marriage life? 2) do I get back my sperm count healthy again? 3) is this will make problem in my wife's pregnancy and if it does then what should I do to take away this problem (naturally)?
