I have been taking test cypionate for quite some time now and have had 2 sperm tests where I had ZERO sperm. Now I have met a woman and am wishing I knew this would make me sterile as I would have stashed a few ounces of my sperm. The Urologist said I would never make sperm again while the Endocrinologist says that I would need to be off T for a few months and could make sperm again. Anyone know anything about this? Thanks, E
