Trying to conceive

Okay so me and my fiancée is trying for a baby.. We’ve tried everything to conceive but no luck.. his cum is clear could that mean he’s infertile?? I do have ovarian cyst but the doctor says I’m still able to conceive... I’ve tried talking to him about seeing a doctor but he get offended.. like I’m not trying to be rude but I’m just not sure what to do.. any advice
