Vasectomy reversal

Victoria
My SO just had his vasectomy reversed- 11 years after the vasectomy. We researched and found a very good doctor in Boston, and were given a 90ish % chance of success. I'm still so nervous something will go wrong! He has 2 teenage boys and I am 15 years younger than him- so I absolutely want my own kids and we would love a girl. Does anyone have any success stories? We are getting married in August so I'm back on BC until then... Then it's on!
