IVF Success Rates Can Be Misleading

According to a study, some fertility clinics are manipulating their reported IVF success rates.

Database of excluded cycles

Fertility clinics are obliged to report the number of in vitro fertilization (IVF) cycles they conduct, but a new study highlights the information when they found out that practices misleadingly report high success rate.

Researchers examined a database at excluded cycles by the Society for Assisted Reproductive Technologies (SART) and discovered the proportion of cycles that were started but had not reported final results, either successful or unsuccessful.

Thirteen U.S. clinics out of 341 are responsible for half of those excluded cycles, and they reported significantly better overall successful pregnancy rates than the average fertility centers.

Mandated to report data on completed cycles

Researchers said some excluded cycles may disappear from the database when clinics take frozen embryos from several rounds of fertility procedures and only implant the one that looks best. This reason is either as a surgery, or to make their success rate look better.

According to Dr. VitalyKushnir, who led the research at New York’s Center for Human Reproduction, it’s probably a combination of clinics that are doing this unconsciously and some that are doing it intentionally.

Researchers strictly discussed that fertility clinics are required to report their data on completed UVF cycles to the U.S. Centers for Disease Control and Prevention (CDC).
