. Human Embryo Culture. UK, Nuffield Council on Bioethics, 2017.

This document collects together a number of reflections on the statutory time limit for maintaining human embryos in culture. This issue was raised for consideration at the Nuffield Council's annual 'forward look' meeting in February 2016. It was given an additional impetus the following month by the publication of research that suggested, for the first time, the possibility that embryos could be cultured for longer than 14 days (the current statutory limit in the UK). This led the Council to hold a workshop with the range of experts to discuss whether, after 25 years, there may be persuasive reasons to review this legal limit or whether the reasons for its introduction remain sound.
