Sorry, didn't see this before. Sperm count can be raised quite easily, by changing to boxers if he doesn't already wear them, drinking heaps of water, staying away from alcohol and soft drinks - ESPECIALLY diet soft drinks, taking Menevit. He can get acupuncture as well. I think it's about 3 months before you'd see a change in his count/morphology.

As for PCOS, I've conceived 4 times with PCOS and DH with very low count. I personally wouldn't recommend going to IVF straight away when there's other things you can try, unless there's other factors to consider, like your age. There's a PCOS conference in Melbourne this October, I'm going because I think it's gonna be brilliant for info, most of the doctors over here aren't up on PCOS.

Good luck
