There is a misperception that pregnancies achieved with assisted reproductive technology (ART) are more prone to miscarriage. The reason for this misperception is that pregnancy tests are done very early in the cycle when a woman has undergone ART. Women who have not undergone ART do not generally have a pregnancy test this early on. Since miscarriages are more common in this early stage of pregnancy it is understandable that more would be detected. In fact, when ART results are matched against control populations of a similar age group, there appears little, if any, tendency for increased miscarriage.

The following table summarizes the United States clinic reports for all cycles initiated in 2003, and reported in 2005.
