Should We Encourage Three Parent Embryos?

This is a sort of follow-up to my last article. In fact, this is the topic that inspired it. There was an article written by Alex B. Berezow, a microbiologist, arguing that we should support the creation of three-parent embryos. The United Kingdom is drawing up regulations for this procedure. Now, In-Vitro Fertilization (IVF) is a controversial and currently immoral procedure because excess embryos are always created and destroyed. Since human life begins at fertilization, creating excess embryos and terminating them is wrong. But moral issues pertaining to IVF aside, is creating three-parent human beings wrong?
