I've found a couple of more anecdote type articles of couples that did choose not to do the necessary genetic testing before implantation. The ultimate problem is that those tests are optional. And "optional" usually translates to: pay more money.
I'm sure the tests would greatly reduce the chance of abnormalities, and I've also seen articles suggesting this. What I haven't seen though is an indication that most couples go through them, and that they're indeed willing to throw away all embryos that carry a condition at the risk of drastically reducing (or even eliminating) their chance at impregnation.
