The only way to determine if a man or woman is sterile is to have them tested. There are a series of tests that can be done on a sample of the man's sperm to determine if he is sterile.
As a rule of thumb this is what a man needs to be considered fertile:
2ml or more of semen
2 million sperm per ml of semen
50% or more of the sperm must be correctly formed
50% or more of the sperm must have good motility

The chances of being sterile are very low. It is typically only around 2 to 4 percent of people who are sterile.
