I'm intrigued to know what "surplus" means in this context.

I assume that it refers to embryos created in vitro for infertility treatment but which are not needed for implantation once a viable pregnancy has been confirmed on the prospective mother?

If this is the case, what else can be done with them?

Wouldn't they be destroyed anyway?

Think cloning. Cloning of humans. That's what stem cell research is.
