Is it possible to reverse a tubal?

40% to 85%. But it depends on several factors: the best candidates for tubal reversal are women younger than age 40 who had sterilization surgery immediately following childbirth. Have you considered adopting? Probably cheaper, and the success rate is 100%! and you would be doing a good thing. A very good thing.
Depends. Fertility can be obtained after a tubal ligation either through surgical repair (if amenable to reversal) or through ivf (tubal bypass). Tubal reversal success will depend on health of the tubes as well as chances to conceive overall. Ivf does not require tubes and therefore success will depend on the age of the female as well as presence of other infertility factors.
