Former smoker - IVF success rates


I’m 37 and a former smoker, we have unexplained fertility issues (though my husband’s sperm analysis came back better than normal, so I’m thinking the issue is egg quality since we had one previous miscarriage) and I’m wondering if any of you other former smokers can share with me how many egg retrievals and transfers you went through before a successful pregnancy. We’re paying out of pocket, so I’m worried. Thanks so much!
