This case was the first of its kind to address questions of personhood [5] in the context of in vitro [6] fertilization [7] of a human embryo. It laid a foundation for future cases to work from: specifically, this case established the importance of prior written agreements for disposition of frozen embryos. This was also the first court decision to borrow the word ?pre-embryo? from bioethics to...

BACKGROUND The high number of IVF procedures performed in Israel has had an unforeseen consequence: accumulation of large amounts of surplus frozen embryos. After five years that the frozen embryos are kept for free, patients need to make an embryo disposition decision. One option is donation for research. The donation rate in Israel is very low. Our aim was to understand the attitudes, values ...

A commercially viable cattle embryo transfer (ET) industry was established during the early 1970s. Initially, techniques for recovering and transferring cattle embryos were exclusively surgical. However, by the late 1970s, most embryos were recovered and transferred nonsurgically. Successful cryopreservation of embryos was widespread by the early 1980s, followed by the introduction of embryo sp...

It is uncertain how long IVF units can keep frozen embryos. Few data exist on success of embryo transfer for embryos that have been cryopreserved for many years. We report the delivery of healthy twins following the transfer of embryos cryopreserved for 12 years. To the best of our knowledge, this is the longest reported successful human embryo freezing.
