Frozen Embryo Transfer vs. Fresh Embryo Transfer A fresh embryo transfer occurs in the same cycle as the IVF cycle. The eggs are retrieved and fertilized in the lab. The embryos are allowed to develop and are then transferred back into the woman’s uterus around 5-6 days after the retrieval. A frozen embryo transfer is a little bit different. In this type of cycle, a woman undergoes IVF, her eggs are retrieved and fertilized in the lab, and the resulting embryos are allowed to develop. On day 5 or 6, the embryos are frozen instead of being transferred back into her uterus. Preimplantation genetic testing can be performed on the embryos before they are frozen to screen for common chromosomal diseases, and also to identify the gender of the embryo. The transfer would occur once these results came back.
