Cryopreservation of biopsied embryos at the blastocyst stage.
BACKGROUND The availability of an efficient cryopreservation program is especially important in the case of embryos that have undergone blastomere biopsy for PGD. Unfortunately, the freezing/thawing of biopsied embryos has given disappointing results when performed at the cleavage stage. In this study, embryos diagnosed as normal after PGD were grown to the blastocyst stage, frozen and thawed f...
متن کاملEfficacious cryopreservation of 2 - cell stage mouse embryos via
S Introduction ince Whittingham et al. first succeeded in cryopreserving mouse embryos in 1972, there has been remarkable progress in both basic and applied research enabling us to preserve the embryos of at least 13 more mammalian species. Moreover, every process used for freezing and thawing embryos has been refined and extremely simplified. Specifically: 1) The time required for the embryo t...
متن کاملI-11: Cryopreservation of Canine Embryos
Background: The assisted reproductive techniques (ARTs) such as in vitro fertilization, embryo transfer and cryopreservation of gametes have considerably contributed to the development of biomedical sciences in addition to improved breeding in domestic animals and infertility treatment in humans. However, ARTs used in canine species have strictly limited utility when compared with other mammali...
متن کاملOptimized protocol for cryopreservation of human eggs improves developmental competence and implantation of resulting embryos
UNLABELLED BACKGROUND Successful egg cryopreservation has many potential benefits to a variety of patients. However, a superior standard protocol describing all aspects of oocyte cryopreservation has not yet been identified. Oocyte cryopreservation is still a technical challenge for many infertility clinics. To maintain satisfactory clinical outcomes, there is a need to develop an easy to us...
