Guidelines for embryo transfers (US)

“The American Society for Reproductive Medicine (ASRM) and the US Society for Assisted Reproductive Technology (SART) have issued new guidelines limiting embryo transfer during IVF procedures to reduce the occurrence of multiple births. Announced at the annual ASRM meeting, held in New Orleans last week, the revised guidelines recommend that no more than two embryos should be transferred to women under 35 during a single cycle of IVF treatment, and that clinics should consider the possibility of transferring only one. For older women the recommended number of embryos increases, but to no more than five. The guidelines state that for women aged between 35 and 37, up to three embryos should be transferred, with up to four recommended for women aged between 37 and 40, and no more than five for women over 40.”
