Women who wait for six months or longer after a miscarriage to have another frozen embryo transfer could be more likely to get pregnant and have a healthy baby, according to international experts. The researchers compared the time frames of 2433 women who underwent a frozen embryo transfer within a year of a miscarriage in China. 338 women had the transfer less than three months after their miscarriage, 1347 had a three to six month interval and 748 had a six to 12 month interval. The researchers say the women with an interval of six to 12 months were more likely to become pregnant, have a live birth, and have a healthy live birth, while those with intervals of less than six months were more likely to have another miscarriage.

About The Study: The results of this study of 2,433 women who received in vitro fertilization treatment suggest that delaying frozen embryo transfer for at least six months after a preceding clinical pregnancy loss was associated with beneficial pregnancy outcomes. Further prospective studies are needed to confirm these findings.
