Thawed embryo replacement

When there have been embryos frozen following an IVF cycle, they can be thawed and transferred into the uterus in subsequent cycles. İn most cases a transfer cycle will be manufactured, using drugs, to ensure the uterus lining is sufficient and to time the embryo thaw with the appropriate uterus stage. Improvement in assisted conception technologies have seen pregnancy outcomes from frozen embryo replacement cycles improve to such an extent, that they now have an equal to or better pregnancy outcome than fresh embryo replacements.
