Don't give up hope! Our Dr said we had little chance of ever getting pregnant the 'normal' way coz DH's sample was very poor - less than 1% normal and motility poor too. We were gutted and she said the only hope we had was ICSI. She recommended DH taking a single vitamin supplement but I did my own research and listed numerous things (10 or more) that were thought to improve the sample. Took the list (with recommended amounts) to the pharmacy and was shown some superduper mega vitamins which included nearly everything on my list. Just had to get additional Vit C and Folic acid. DH started taking once a day. In less than 6 weeks his sample quality had more than quadrupled and the Dr couldn't believe it!
Anyway, to cut a long story short we ended up trying IUI first (Dr recommended we gave it a couple of tries coz it's much cheaper than ICSI) and it worked first time!! I checked the stats online and with DH's sample, we were given a less than 6% chance of success. It's worth a try...
Do a bit of research about how to improve the quality of his sample and I'm sure you'll find the same info I did -If I still had my list I'd forward it to you to save you the time.
Both me and my DH know how you feel and hope you get lucky like we did. Take care, x
