Future parents need to know this: multiple pregnancies are a factor of risk and are considered an adverse outcome after assisted reproductive interventions. To reduce the frequency of this complication, a limitation on the number of transferred embryos has been advocated for good prognosis patients. This is the argument of a study published by the GeneraLife team on “Human Reproduction”. Results show that the application of a ‘single embryo transfer’ policy, combined with enhanced laboratory procedures including systematic application of blastocyst culture, Preimplantation genetic screening, and vitrification, helps to increase safety and efficiency.
