With the above discussion of fertility cycles, this explains why I have known so many women who went back to school to get advanced degrees after having children. It is really tough even then for other reasons, but it may be the best way to balance getting an advanced degree and having children.
On the other hand I have to admit that I am more conflicted about this than some people. In Tonga there are people who have children to then give them away to their relatives who can't. I guess that is a little different than the issues of articficial insemination an in vitro fertilization, but I do have to say that biological parentage is not the only possibility. "descendants" are not neccesarily biological ones, especially if you hold them out as your biological children. Wells might not have even known the child was not Clark's. People might just assume that the thinks that create Superpowers do not activate with a half-kryptonian child.
