This should be a fun thread. Or interesting at least.
My mother was an in-vitro fertilization specialist. I spent many of my childhood days in the lab she worked in. They were kind to her, being a single mother and let me hang around. I've been fascinated with the procedure from childhood. Whilst she was introducing sperm to eggs in petri dishes, I was cutting out and arranging chromosomes. Rambling. Back to the topic.
No, I don't see it as wrong. Or a sin. Some men are sterile. If a guy and his partner wanted a child, and he could not impregnate, then donor sperm would have to be used. God has always valued life. In Biblical days if a man died before being able to have his wife bear a son, the brother of that man would take the wife, impregnate her and if a son resulted, that boy would take on the name of her deceased husband. Anyway, I don't really see a difference. Sure, one was for the honor of the name-lines continuing, and in modern society it's for the reason of having a child, I really don't see how it's my place or anyone else's place to say that the desire to bring a child into a happy, loving home is wrong, no matter the method.
