When did man alone become the author of life vs. a persons desire to have a “natural child” via in vitro? What ever happened to adopting if infertile and raising that child as your own? In vitro can be looked at as just as selfish as abortion if you think about what it says. Whether a person chooses to end a pregnancy via abortion because they don’t want that life or going to a lab and forcing life to be manipulated in a test tube and injected are both “me” thinking. We feel we are entitled to have “our own” child or abort “our own” child. Both are a symptom of our own selfishness.
No matter how cruel it sounds, adoption is not going to prevent the ending of two individuals' genetic lineage, as a relevant biological entity.
There is absolutely nothing selfish in wanting to see one's genes preserved. In fact, it is the primary rule of life on this planet.
"We feel we are entitled to have “our own” child... ...symptom of our own selfishness."
Welcome to the rules of life.
