It depends on what is blocking your tubes. If it's scar tissue that is blocking the tubes, this won't help. If it is liquid, generally this is the best way to remove the blockage. I'm not sure they will know until they do the procedure.

My tubes were removed during excision due to scar tissue. There was no reopening them. The lumen was a pinpoint. No egg or sperm could have gotten through. And the fimbriae were clubbed.
