Husband’s sperm morphology is 2%, thoughts please?

J.

We are confused and surprised his morphology came back at 2% since we have conceived twice already (one MC and we have a two year old). All of my tests and ultrasounds came back great and clear, no cysts or blockages... the doctor said they dont know what causes it and we may have to do <a href="https://glowing.com/glow-fertility-program">IVF</a>? is there anyway to improve morphology or has anyone have success doing <a href="https://glowing.com/glow-fertility-program">IUI</a> or naturally conceiving with 2% morphology? Any comments or experiences would be so helpful we are very confused and worried and hoping to avoid <a href="https://glowing.com/glow-fertility-program">IVF</a>...
