Any others like me?

Hi there guys! 
My partner has CF and we have been trying for a baby for 4 years now with no luck, we are from the UK so at the moment you have to be 23 to start IVF I believe and I'm not there yet. 
Was just wondering if anyone else has a partner with CF? I hear a lot of stories about women with the condition who conceive but not a lot about men with the condition who do? 
Any help would be great!
