Now what?!

Hi everyone so my husband and I have been ttyc for 2 years now and nothing has happened. I've done all the necessary testing and everything comes back normal. I just had a hsg test and it was perfect. Today my husband went to the dr and they told him his sperm count is 5 million( suppose to be around 20 million) so it's very low. What do we do now? <a href="">Ivf</a> is soooo expensive but that's the direction we look like we're headed. Any suggestions? Ideas?... Thank you!
