Is modern medicine/surgery stopping the evolutionary progress of the human race?

Answer:
Here is an example that illustrates this very thing. Years ago, I became concerned about this. I think that whenever we block natural selection we affect the evolutionary process. (It does not stop evolution, it just has an unnatural bent in the line.)

High numbers of C-section births negatively affect natural selection. I figured it it went unchecked, it could eventually lead to female bodies that are incapable of giving birth naturally.

Fertility treatment for those who cannot reproduce permits reproduction of the genetic make up that is the problem. Again, if unchecked, how long before the entire race has reproductivity problems.

So we end up in a world in which females cannot reproduce or give birth naturally. I am not too worried though, as I figure science and technology will fix it before it actually becomes a problem.
