Testing of fertilized eggs that undergo in vitro fertilization treatment to identify genetic diseases before pregnancy has reduced the rate of miscarriages in women who had repeatedly miscarried, a large-scale clinical trial has found.
The Japan Society of Obstetrics and Gynecology, which analyzed the clinical trial covering 9,097 people at 200 facilities, concluded the method proved to be effective in reducing the miscarriage rate in results released Sunday.
The trial analyzed women who had suffered miscarriages repeatedly or had not become pregnant even after transplanting fertilized eggs in their wombs multiple times.
