Does the Volume of the Embryo Culture Medium During Embryo Transfer Affects the IVF Outcomes?
Low Versus High Volume of Culture Medium During Embryo Transfer: a Randomized Clinical Trial.
研究概览
详细说明
The volume of culture medium used for embryo transfer is a variable that has been speculated to affect the IVF outcome. It is known that ultra high volume (>100 μl) of medium during embryo transfer may result in embryo expulsion out of the uterus or ectopic pregnancy. Similarly, some authors advocate that ultra low volume of transferring medium (<10 μl) may negatively affect pregnancy and implantation rates.
However small differences in the volume of the culture medium may favor the outcome of the embryo transfer. The aim of this study was to evaluate if the use higher volume (40-45μl VS 20-25 μl) of media used for embryo transfer affects the clinical outcomes in fresh IVF cycles.
