Damaged fallopian tubes

Laura • We got married on 9/13/14. After one miscarriage and 2 years of fertility issues, we are starting the IVF journey!!

After a lot of different testing and surgeries, it looks like both my fallopian tubes are damaged. (likely something I was born with) Before starting IVF my doctor wants me to get both removed. He said when they are damaged, they release a chemical that can prevent pregnancy from occurring? Has anyone else ever heard about this? I tried doing some of my own research, but didn't find anything.
