Percentages of ART cycles using fresh nondonor eggs or embryos that resulted in miscarriage, by age of woman, 2006

A woman's age not only affects the chance for pregnancy when her own eggs are used, but also affects her risk for miscarriage. The above figure shows the percentages of ART cycles started in 2006 that resulted in miscarriage for women of different ages. The percentages of ART cycles that resulted in miscarriage were below 14% among women younger than 35. The percentages of ART cycles that resulted in miscarriages began to increase among women in their mid- to late 30s and continued to increase with age, reaching 28% at age 40 and 56% among women older than 43. The risk for miscarriage observed among women undergoing ART procedures using fresh nondonor eggs or embryos appear to be similar to those reported in various studies of other pregnant women in the United States.
