Many guys with only 1 testicle are healthy and fertile (Lance Armstrong for example).
One testicle is all that is needed for sperm production just like only one ovary is needed to produce eggs. We were lucky to be given a spare.
The way to know if you are able to reproduce is to have a sperm count done. Your family doctor or an urologist could help determine if he is producing viable (living) sperm. The test would be the same as those who have had vasectomies and want to be sure they ARE sterile. A seman specimen would be examined for motile (moving) sperm.
