My DH is pretty good I have to say.

He would stop drinking, come home when told to, eats pretty well. And was always prepared to give a sperm sample without a single complaint or moment of embarrassment.
Heading into IVF, DH is even cancelling important meetings because our family comes first. Its an amazing attitude and one I wish more DH's could have to support their partners.

But unfortunately men often seem to have this obliviousness to the process and really don't comprehend their 50% of the creation process!!
