Source: Brown University | Summary: The US has reached a record-high rate of twin births, and the use of in vitro fertilization is part of the reason. But in a new commentary, an expert argues that implemented differently, IVF could instead reduce the rate toward natural levels.

"The twin birth rate in the U.S. has surged over the last 30 years, mostly because of reproductive technologies including in vitro fertilization. Though it's partly the cause, IVF could also be the most promising solution to reducing unintended twin births, argues Dr. Eli Adashi in a new editorial in the American Journal of Obstetrics & Gynecology.

For that reason, many physicians and public health officials consider technology's artificial contribution to the soaring twin birth rate to be problematic.
