Testicular cyst! Anyone husband have and affected fertility

We have been trying for 13 months now... going to start Clomid this cycle. My husband was just diagnosed with a cyst on this testicule. It's painful so they maybe want to do surgery. Anyone's husband have it and be the reason for infertility? Or have a complication due to removal? Just looking for something to help me stop stress about! Scared we may not be able to conceive. TIA.
