Signicant sperm count drop?!

Katie

I had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> this morning and my husbands sperm count was 25,000. When it was checked 5 months ago it was 9 million. What can cause that? There have been no illnesses etc. she referred him to a urologist. We went ahead with the <a href="https://glowing.com/glow-fertility-program">IUI</a> but I’m feeling really discouraged. Any thoughts?
