How about adopting embryos? There are millions out there waiting to be adopted they can implant them right into your uterus!
Well, I think IVF usually has a 50 percent chance of working. If I were you, I would set up an appointment with an RE to get some more information. They might also be able to run a few tests on both you (mainly blood tests, and perhaps monitoring by sonogram) and your DH (semen analysis) to give you a better idea of the success rate, based on your individual situation. Good luck!
I didn't know anything about tubal ligation until I read your post. I quickly looked up on the internet. This is what I got from the babycenter.com website. I am not sure if this is going to be helpful.
Can a tubal ligation be reversed?
In some cases, yes, but don't count on it. Reversals are expensive and insurance companies rarely cover them. They're also much more complicated than closing or cutting the tubes in the first place, and your chances of being able to conceive after a reversal are uncertain. Only 20 to 40 percent of women who reverse a tubal ligation go on to give birth successfully (and your chances for an ectopic pregnancy increase). Tubes that are closed off by cauterization can't be put back together properly, because the heat destroys their delicate lining.
