Mixed feelings on this.
I love the idea of helping women (real women) conceive when some physical condition prevents them. But I HATE them destroying the multiple embryos when more than one takes. I’d rather see them requiring them to be implanted one by one. Keep doing it until one takes.
And the leftover embryos, I’d like to see those no longer be the property of the parents if they no longer want them. Some way of giving up control so that if they say they’re unwanted, they can be donated to women with even greater physical problems.
