Could you tell me what are my chances of having a baby after having a tubal ligation reversal?

Please ask the doc: Who is doing it as that doc should be able to give you odds.

Many factors: Your chances are based on several factors, including your prior fertility, the tubal status after repair as well as presence of any male factor fertility issues. The biggest factor is age of the female partner. At age 48, your fertility declines significantly making it very difficult to conceive spontaneously even if you had not had a prior tubal ligation. Please see a fertility specialist.
