Researchers in Canada Call for Policy to Mandate Single-Embryo Transfer in IVF

JAMA. 2011;305(18):1848. doi:10.1001/jama.2011.602

Researchers in Canada have come out in support of mandatory single-embryo transfer during in vitro fertilization (IVF) after their recent study showed that such a restriction would prevent deaths and severe complications associated with multiple gestations from IVF.

Investigators reviewed records from the neonatal intensive care unit (NICU) at the Royal Victoria Hospital in Montreal, Quebec, to determine how many infants admitted from 2005 to 2007 were from IVF-related multiple births and whether that proportion changed over a 10-year period. They also tracked the infants' complications and medical interventions they received.
