Slow Oocyte Freezing .

摘要

The science of cryobiology and IVF have developed in parallel over the past 50 years. Artificial insemination on a large scale, only became possible with the pioneering work of Polge et al. (1949) who demonstraded that cells (in this case fowl semen) could be recovered in a viable state from very low temperature.Oocyte cryopreservation has been a much anticipated advance in human IVF and reproductive sciences that may extend female reproductive potential, while avoiding ethical and legal complications originating from the storage of embryos and fertilized oocytes.
