Part of the problem with IVF is that the sperm and egg are chosen basically at random. In natural conception, only the strongest sperm can make it to the egg. With the standard IVF procedure, they just pick a sperm and an egg that look reasonably healthy, and inject the sperm into the egg. Since you don't have the same degree of sperm competition, the sperm is more likely to have high mutational load. If you were to squirt donor semen into the woman's vagina and conceive the kid that way, or create a new IVF procedure that more closely resembles natural conception, it would theoretically be less dysgenic. Another problem with sperm donation is that the two parents aren't necessarily genetically compatible. With natural reproduction, the parents select each other based on assortive mating.
