Suppose a couple, having problems with fertility, decides to try IVF as a means of having children. For the sake of the hypothetical, let’s say initial fertilization goes very well and the couple ends up with 30 viable embryos. After 8 pregnancies with three embryos implanted each time, the couple is exhausted and now has 24 children. They are done having kids.
What does the couple do with the six remaining embryos? You make the call.
