Single embryo transfer 'may improve IVF treatment'

New research from the Reproductive Associates of Delaware (RAD) has indicated that single embryos cultured under proper conditions have a greater chance of implanting and developing successfully in women aged 35 and under.

IVF experts at the US centre found that 55.1 per cent of women in this age category achieved a live born pregnancy following a single embryo transfer, with an average of just 1.4 embryos being used.

The national IVF success rate during the year of the study was 46.1 per cent, with an average of 2.2 embryos used – potentially indicating that the RAD method may be more successful.

Dr Ronald Feinberg, IVF medical director at RAD, claims the higher implantation and live birth rates at the Delaware centre can be attributed to two factors.

He points to adherence to strict laboratory protocols which allow for the culture of embryos to the blastocyst stage – therefore allowing careful embryo selection – plus evaluation and treatment of patients for underlying infertility problems prior to IVF.

Dr Feinberg adds: "Blastocysts are also able to be preserved in a frozen state for future use. We believe that the single embryo transfer approach is also highly effective for thawed embryos, as shown with our pregnancy and implantation rates utilising these embryos."

Last month, researchers from the Radboud University Nijmegen Medical Centre, Netherlands, presented evidence disputing the belief that women with symptoms of anxiety or depression are less likely to become pregnant through IVF treatment.ADNFCR-2094-ID-19078499-ADNFCR
