We had male factor also.. but didn't have an issue with viscosity though.. I'm pretty certain that it would be easy to fix.. especially with IUI .. they wash the sperm anyways.. so I don't see it as a problem.. We had problem with the count, motility and shape.. and those weren't fixable unfortunately..
so I'd look at is as a good thing...
I know the feeling of pcs'ing and starting over.. My DH is in the army.. That's what took us so long... we kept moving from place to place.. but, keep at it.. You'll be pregnant in no time.. and You'll have your baby in your arms before ya know it !!
