Abstract:
The application of embryo cryopreservation is now a routine feature of clinical ART programs. The cryopreservation of embryos following in vitro fertilization (IVF) provides numerous advantages to couples. The first advantage is that of further possibilities for conception in addition to those achieved from the fresh cycle. Secondly, the cryopreservation of embryos provides a method of storage of excess embryos, thus helping to alleviate pressures to transfer high numbers of embryos. Thirdly, embryo cryopreservation plays an important role to prevent severe ovarian hyperstimulation, thus allowing a delay of embryo transfer to a later cycle and diminished the severity of hyperstimulation. Excessive embryos with good quality can be stored at cleavage (4-8 cell) or at blastocyst stage. The success rate for using cryopreserved-thawed embryos was reported to be 4-20%. In this paper, we reported the first clinical pregnancy in Vietnam from a subsequent thawing cycle
