Baby girl born from record-setting 27-year-old embryo

There's a pretty hard barrier between embryo and implantation, when it comes to IVF. The cells in the embryos are 3 or 5 days post-fertilization, and they're just working off of nutrients from the egg itself.

Replicating the actual implantation process, where the embryo gets nutrients from the uterus itself, we haven't made substantial progress towards AFAIK.

I think the reason we are not making large progress is simply because it's forbidden research. There is an international agreement called the 14-day rule preventing researchers from culturing embryos past 14 days.

Isn’t that rule about human embryos only? Are there similar restrictions on pig or sheep embryos?
