The only factor that can affect this aspect (as well as the rest of things) is the state of mind. But I don't think it's a problem to find,or have, or keep a partner.
My baby doll Olivia had Achalasia and Anemia a few months ago, like in April she seemed fine but her esophagus was a little bad but that's okay I guess, now since its october she doesn't have achalasia anymore but she still Has anemia.
