What exactly do you think happens to the "left over" embryos after IVF?
Let me guess... the women sell them? I don't know and I really don't care. What's good for the goose is good for the gander.
Just a clarification...this is NOT IVF (In Vetro Fertilization is done in the occurence of infertility when sperm and egg are united externally and then the resulting embryos are implanted in the uterus). The women in the article, are being inseminated with donated sperm...no external fertilization. The woman's fertility is tracked (and in many cases enhanced by fertility drugs) and the sperm is introduced to the reproductive tract at the optimum time for fertilization. There are no left over, or unused embryos. Fertilization either takes place, or it doesn't.
