Low sperms count

Tiffany • 😆mother of 2 beautiful children.
Does anyone know how to know if a man has low sperm count with out the testing? My fiance is 25 and has never had a baby. We have been trying for almost a year now and nothing has happened. Anybody have any suggestions other than seeing a doctor bc at the moment we have no insurance and don't have the money to go to a doctor.
