Thanks for the information.
So, would it be correct to say that no current IVF procedure avoids producing unwanted embryos?
Yes, as far as I know, IVF always results in extra fertilized embryos.
I believe your IVF statement is true but I do not know for certain. I only know that one counterexample for ‘artificial insemination.’
I am not a medical professional though I am pretty good at diagnosing my own ailments using search engines:)
