Global cattle genetic market is experiencing a change of strategy, large genetic companies,
traditionally recognized in the artificial insemination field, have also begun to operate in the …

The expansion of the use of in vitro production techniques has revolutionized the bovine
embryo market. In the last decade, we have seen the number of in vitro produced (IVP) …

There are still immense differences in the quality of in vitro produced embryos compared to
their in vivo generated counterparts. These differences include a higher sensitivity of in vitro …

Embryo cryopreservation represents a pivotal tool for the long-term storage and exchange of
valuable genetic resources of livestock and endangered species. The innumerable …

Considerable progress has been made in the improvement and simplification of
cryopreservation procedures routinely used in embryo transfer programs. Conventional slow …

Contents Cryopreservation of in vitro‐derived bovine embryos is a crucial step for the
widespread reproduction and conservation of valuable high‐merit animals. Given the …

Transfer of fresh sheep embryos frequently results in higher pregnancy rate compared to
cryopreserved ones, possibly due to a failure in the communication between the …

Four-and eight-cell embryos from 3 mouse genotypes were cryopreserved to study the
relationship of genetics and freezing variables on post-thaw survival. Embryos from outbred …

Studies of embryo cryopreservation efficiency have focused mainly on technical and embryo
factors. To determine how a slow freezing process affects embryo and fetal development, we …

The purpose of this study was to determine ultrastructural and cytoskeletal changes that
result from vitrification of porcine germinal vesicle‐(GV‐) and meiosis II‐(MII‐) stage oocytes …
