Miscarriage linked to sperm.

Topaz • Married. Dog mom. Go CAVS!
Experiencing miscarriage #5 all between week 4 and 6. They have run all the tests on me-HSG, saline hysterodalingagraph, endometrium lining, everything under the sun- I'm good. But they have never tested my husbands sperm. Could he be getting me pregnant but have malfunctioning sperm that's effect the development?

Update: Husband has low morphology less than 2%. So apparently we are candidates for <a href="https://glowing.com/glow-fertility-program">ivf</a>. Although I haven't spoken to my RE yet. I'm sure this is our problem. Keep you posted.
