The “14-day rule”—broadly construed—is used in science policy and regulation to limit research on human embryos to a maximum period of 14 days after their creation or to the equivalent stage of development that is normally attributed to a 14-day-old embryo (Hyun et al, 2016; Nuffield Council on Bioethics, 2017).The ’14-day rule’ is a staple of human embryo research governance. Though implemented in various ways in different countries, its essence is the same wherever the limit applies: it stipulates that human embryos, for whatever purpose, should not be grown in vitro for longer than 14 days after the point of fertilisation.Once embryos have been produced, it is permissible to destroy them in research, provided that they are unwanted and that the parents consent.
