I still think there’s something important that we don’t know about the procedure.
Didn’t she say that six embryos were implanted on each previous occasion, resulting in only one or two fetuses in each occasion, because she had some kind of condition that made it difficult to get pregnant?
And now, six embryos are implanted, and, not only all 6 survive, but they multiply to produce 8 fetuses? The chance of 6 single pregnancies resulting in 8 babies simply because of dividing embryos is something like 1 in 800. Even if the chance of twinning is higher in IVF, that’s still a very unlikely outcome.
