I second Patrick.m, get to the fertility clinic. My wife and I went through about five years of treatment to try and start our family. My test levels came through on the low side of normal but my sperm count was low. I currently have no history of PED usage so not sure what to blame for my issues. The only way to do it in the end was to go through In vitro fertilization. The first attempt failed and we lost all 13 embryos which was devastating for my wife and I. We decided to give it another go even though my wife found all the drugs and treatment difficult to manage. Jump to today, I'm 40 and as I am typing this I'm holding my 5 month old son. I don't think he wants me to lift, sleep or even visit this forum... lol. Just get started on the road as soon as you can as it sometimes doesn't work the first or even second time around. I wish you the best of luck, as I can speak from experience that it is a difficult journey.
