The data says if you are overweight or obese, a 10% reduction in body weight is supposed to help. I would keep trying, even given your DH's SA situation, because low count/ motility still equals count + motility. You may have, in theory, less of a chance than someone with normal count and motility - but that's not the same thing as "no count" - was a girl on here about a year ago I was friends with and her husband was Dx'd with NO SPERM, total azoospermia. You may not have the best odds, but it would still be worth trying - if I were you, at least. Most people I've seen get BFPs over the past 14 months never really did anything different their BFP cycles, it just didn't work until it did. So, I'm going to keep 'trying' (as casually as one can without totally missing the boat) and continue working on getting my hormone situation sorted and my weight down. With as little emotional investment as possible, because I long ago gave up BFP thoughts and agree with Pirate about not even being able to imagine it actually happening, for real.
