Were these with your eggs, or with the eggs of an egg
donor? The chances for a successful pregnancy in a
45 year old using her own eggs is only 1.2% (refer to http://www.cdc.gov/ART/ART2004/index.htm). Using an egg donor, the chances each month are close to 50% (same website). Thus, even with a donor there is only a 50-50 chance each time you try. By far egg donor or adoption at age 45 are the most realistic roads to take to have a family. Good luck!
