What is done with any "leftover" embryos?

Embryos which are not transferred in the retrieval cycle are maintained in culture for an additional 2-3 days. Those embryos which progress to the blastocyst stage can then be cryopreserved, if that is the couple's wishes. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
