Ok, but...is there any particular reason to think IVF is not safe, other than a superstitious ookiness about the methodology of the thing?

40 years without any such indication is fairly strong evudence, IMO.

1) There are a lot of studies showing an increased risk of various conditions, e.g. heart problems for babies conceived with ICSI.

2) It stands to reason that while some infertility is caused by issues that having nothing to do with the genetics of the sperm or egg (e.g. vitamin E deficiency), other cases may be caused by genetic conditions that have coevolved to cause fertility issues to prevent them from being passed along.

3) You'd have to completely rule out the possibility of sexual selection at the gamete level, even though this idea has been gaining traction in the last few years.

Good point. Here's my try at it:

IVF: Seems logically sound, since it is doing the same thing that happens in natural conception, just outside the body.

But in vitro gametogenesis (IVG)—the technique the article talks about—could logically have similar issues to cloning.

For example, telomere shortening & accumulated DNA damage come to mind, but I'm no expert.
