Study: “No justification” for transferring three or more embryos in IVF
Thursday, 2 February 2012
The Los Angeles Times “Booster Shots” blog reports, “A recent study … concluded that doctors can consider transferring two embryos in some women but that there is no justification for transferring three or more embryos in any patient.”
Researchers found that “the live birth rate was greater in both women younger than 40 and women 40 and older when two embryos were transferred compared with one.
“However, the transfer of three embryos resulted in a lower live birth rate in the younger women compared with transferring two.
“And, among women 40 and older, the transfer of three embryos resulted in a live birth rate similar to two-embryo transfers.”
In addition, “the risk of preterm birth was much higher when three embryos were transferred.” The study was published in The Lancet.
HealthDay reports that the researchers concluded, “Transfer of three embryos should no longer be supported in women of any age.”
