Thanks for posting your query. From your question, I can see that you had a difficult time with your ectopic and surgery after infertility treatment
, but there is hope. With one good tube & 2 ovaries intact you still have a chance of natural pregnancy
provided the semen parameters are normal. But as days go by the fertility decreases. So if you want to have treatment IUI may be tried before IVF. IVF does not guarantee an intrauterine pregnancy, but if you have to have it because of the semen count , you can go ahead with IVF. All the best,take care.
