I wanted to give my personal experience with fertility and my cycles. My wife and I were trying to get prego for a about 6 months. After we just decided it will happen when it's time. So I started a cycle again of test/deca. I know you read everywhere that deca shit down is pretty bad. Well my I think that's debatable, I didn't know but my wife got us scheduled at a fertility clinic. Of course they wanted a sperm sample , I freaked thinking the doctor would suspect something. Well to my surprise my sperm levels were on the upper range. Had high motility rate and good sperm count. I was like what???? Turns out nothing was wrong with either one of us , it just hadn't happend yet. Well I know have a 2 month old daughter with all ten toes and ten fingers. Point I wanted to make is everyone is different. Don't go around shooting your load it to random sluts thinking you're shooting blanks cause you're in gear. Also get blood work done please. I'm still fairly new to this about 6 cycles in , I always get blood work done. It's so cheap andyou don't have to guess. So anyone worried about fertlity , don't be I conceived while on test deca . Well I know everyone is different but I was a success story you could say.
