Trouble Getting Pregnant After LEEP or Cryo?

I was just wondering if anyone here having trouble getting pregnant had LEEP or cryo done on the cervix. I have mild dysplasia and had cryo done a year ago but the dysplasia is back and they want me to have LEEP done. They say it won't cause a problem with pregnancy, but there is not a lot of research on that yet and I know too much scar tissue in the cervix can not be good. I also feel like I may have more of a chance for trouble because my mom had endometriosis (although I have not been told I have that yet) Any comments would be great. Thanks
