"The rate of miscarriage in the general population is amazingly high - at least 25% of pregnancies - but many of these are not noticed, because they occur very early in the pregnancy. Dr. Berger's patients, on the other hand, tend to test at the earliest possible moment and so "catch" these very early conceptions that would otherwise be missed.
Also, our patients are older than the average pregnant woman in the general population, and the rate of miscarriage increases with the age of the woman (and the man), whether she had her tubes tied and reversed or not. As another woman wrote, it is age rather than the length of time the tubes were tied that seems to be important.
It is true that shorter tubes have a higher rate of miscarriage than long ones, probably because the fertilized egg may not have enough time to develop in the tube before it reaches the uterus, where it has to be ready to implant. However, we have seen that even women with very short tubes can go on to have healthy babies. What the TR does is give you the chance to try."
Dr. Berger says that the miscarriage rate is closer to 33% than 25% in the general population.

Tami - If you haven't read them already, the CHTRC site has a lot of statistics right off of their home page. One link below shows pregnancy stats and the other link has pregnancy outcome stats.

I was interessted in finding out how many women my age have a child after a TR, not just how many got pregnant, since I seem to see a lot of posts about miscarriages.
