Regulations 3 and 6 of the Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015 enable eggs and embryos created following the Maternal Spindle Transfer and the Pro-Nuclear Transfer techniques to be “permitted” for used in treatment subject to certain conditions (set out in regulations 4 and 7). Specifically, regulations 3 ( c ) and 6 ( c ) provide that no further alteration can be made to the egg or embryo that is created following mitochondrial donation. The intention is to ensure that mitochondrial donation, as allowed in the regulations, is a specifically defined process by which unhealthy mitochondria is replaced by healthy mitochondria.
