The sweeping changes to the Embryo Protection Act in 2018 enabled in-vitro fertilisation to be unshackled from some of the constraints introduced six years earlier. The changes allowed doctors to be able to fertilise up to five eggs instead of only two, increasing the chances of success. They also made embryo freezing an integral part of the treatment process. But government was very careful back then to steer clear from introducing pre-implantation genetic diagnosis (PGD) on embryos in those cases where prospective parents carry the risk of transmitting a hereditary disease or genetic disorder to their child. In parliament, several government MPs at the time made it a point to emphasise that PGD will not be on offer.
