HI GMan
We've been down this road as well. Tried for 3 years - nothing. Had hubby's sperm tested and his counts were as follows: total count ± 7million, morphology less than 1%. It's supposed to be around 40 million per milliliter and morphology should be above 14%. Doctors also told us we'd never fall pregnant.
I went for 2 AI's but it didn't work. We couldn't afford an IVF and hubby was getting all worked up about it so we laid low for a couple of months. We'd both been taking handfuls of supplements for more than a year. Vit E, Eve Primrose, Zinc, Iron, a good multi vit, Selenium, Folic Acid, etc. Then we started the Ferti Boost supplements for 5 months. His morphology went up to 3% and total count around 17 million after the 4th month. We decided to try another AI the following month, but I fell pregnant 2 weeks later.
It CAN be done. Don't believe the doctors. God will help where medical science can't. But I can also recommend the Ferti Boost. It has worked for hundreds of couples where there was no hope.
So keep on trying and good luck!!
