I didn't say there couldn't be any. I just don't understand why there would be. The egg is just getting stuck. Nothing else is different so I don't see how it's changing a natural process. Eggs don't always make it to the uterus even without the tube being tied.

It's just something I don't understand, which is why I said I said I didn't get it. But I think after 30 years, it's probably too late for me to worry about so I won't bother looking it up. : )
