Dr. Adamson at my clinic has been doing infertility treatments for over 20 years. I asked him about tubal surgery, since I also had blocked tubes. Here is what he said:
Surgery used to be the only option for scarred/blocked tubes, before there was IVF. The pregnancy rates were pretty low, however. One problem was that there are little hairs inside the tubes that move the egg along from the ovary into the uterus. The hairs are very delicate, so usually they are damaged before scarring even shows up. The hairs cannont be replaced. This is one reason there are so many ectopic pregnancies in women with scarred tubes.
Also, in my case, my blocked tubes were filled with fluid. If that fluid leaked into the uterus, it could terminate a pregnancy. So my clinic highly recommended to me to have both tubes removed before starting IVF, which I did in January. It is an outpatient surgery, but fairly involved (i.e. restricted diet, no food the day before, general anesthesia, pain killers, bed rest, $27,000 US !!!!!!!!!). It was surpisingly not painful and the recovery was very fast.
So now, without tubes, I can only get pregnant through IVF, which I actually rather like. So when all those well meaning people tell me about their friends who tried IVF 18 times and then decided to adopt and then got PG naturally, I can say "nice for them, but that won't happen to me". Also after TTC for years, I am relieved that if we stop IVF tmt, that's it. We know for sure we won't be having children and can plan accordingly.
Sorry for the long post. Hope it helps.
