I think that titled cervix can not effect the fertility. The bicornuate uterus is associated with miscarriages but there are a lot of women who have normal pregnancy. I have a cousin she have 3 kids delivered with c-section but she has no miscarr.
fertility treatments may be her best option, but there's also the good chance that nature will take it's course and she'll end up pregnant fairly easily.
I'm not speaking from experience, srry, just what I've run across w/ other ladies here.
