So you now run from the obvious implication of your comments, as well as show your ignorance of the genetic components of reproduction, whether in vivo or in vitro. The idea that a low-motility sperm has defective or diminished genetic material is not supported by the science, nor is the chemical selectivity of the egg cell.
As for you last comment, I just don't get it? You put up a post that would obviously insult anyone with IVF children, as well as anyone with less than perfect children, then can't accept a simple rebuke.
What you chose to read in what I wrote is a total distortion beyond a straw man. Your shrill tone suggests that you are incapable of a rational discussion on this matter.
