Even with one testicle it is possible to have normal semen analysis
reports and conceive. The low sperm count
indicates some issues that need to be looked at. Is this testicle normal sized? Is there associated varicocele? What is serum FSH report? I am not sure Fertigyn
Injections should be started empirically just to raise sperm counts. A proper analysis of the cause should be attempted and treated.
Thanks and all the best.
