February IUI's.

Hi everyone. My husband and I have been ttc for two years. He had a vasectomy reversal done November of 2013. His doctor seemed pretty confident we would be able to get pregnant because the surgery was successful. He has a sperm analysis done twice within the last two years and his count is really low as in 9 million. We have now decided to turn for help with a fertility clinic this coming Tuesday. Has anyone ever had success with an <a href="https://glowing.com/glow-fertility-program">IUI</a> procedure even though the sperm count is low ? If so, how many times does it take to conceive on average with this type of situation? We are really hopeful that going this route will help us to conceive. Any thoughts?
