TTC with sperm morphology

Hey y'all. I'm new here, so sorry if it has come up and I haven't seen it. My husband and I have decided to actively try to conceive in the last couple weeks. I have a child from a previous relationship, but in his previous, they were not able to conceive. He had a sperm analysis performed which showed some morphology, and they tried <a href="">IUI</a>. His ex wife now has a child. We haven't tried to prevent a pregnancy in 3 years, but haven't been really trying until recently. Has anyone experienced anything similar? I am just wondering if we should go to the doctor and start treatment or continue actively trying? 😔
