Welcome! You'll find a lot of support here, and answers to your questions. Your doctors statistics seem really high, but I obviously don't know your individual diagnosis or issues. At this site, you can see a clinic's live birth rates and other information:
Fertility Clinic Reports What you want to focus on is the live birth rate.
National stats are available her:
National Summary With the highest live birth rate at 45% for the less than 35 age group.
You may also find that questions get answered quicker on the main board as a lot of girls who have already done IVF still post on the main board.
Best of luck!
