We also conceived naturally with a morphology similar to yours, and also a poor count and motility. We were told we would need ICSI, but I found out I was pregnant naturally the month before we were due to start IVF.
However, nearly 5 years after dd was born, we haven't been lucky again
I know another person who has also conceived naturally, having had ICSI to conceive her first child.
We gave up alcohol, caffeine, red meat, cow dairy (switched to goat), aspartame, almost everything with preservatives in, and took up acupuncture (both), yoga (me) and chinese herbs (dh) before getting pregnant.
Good luck - and be kind to your dh and yourself.
