Your definition of IDF is flawed no matter how fervently you present it. Many couples have only one embryo implanted because they would not be willing in any circumstance to selectively terminate.
Are you kidding?
Maybe only one embryo is implanted but many others are destroyed.
Do you not believe a human embryo is a human being?
Yep, I was holding that piece back, IVF today has the ability to manage 1 embryo, just happens to be expensive
