fresh transfer
An embryo transfer performed in the same cycle as egg retrieval, typically 3-5 days after retrieval without embryo freezing.
Full Definition
A fresh transfer refers to the placement of embryos into the uterus during the same treatment cycle in which the eggs were retrieved, without any freezing process. This approach is performed when the endometrium is adequately prepared and there are no contraindications such as OHSS risk or elevated progesterone levels. Fresh transfers are typically done 3-5 days after retrieval, corresponding to cleavage or blastocyst stage embryos. While historically the standard approach, many programs now favor freeze-all strategies to optimize endometrial receptivity and reduce OHSS risk.
Usage
Usage note: Distinguish from frozen embryo transfer (FET) in all documentation.
