Sex-specific, generic diseases are only avoided a majority of the time, the process is not near 100% accurate and therefore the medical benefits cannot be used without considering of the medical costs. Pre-implantation genetic diagnosis involves the development of embryos outside the womb, which are then tested for gender. One or two of the desired gender are then implanted in the womb. Those that are not of the desired gender, or are surplus to requirements are destroyed (typically, over a dozen embryos are used to select a single one to be implanted). A human life has been created with the express purpose of being destroyed. This is another form of abortion – only the conception is deliberate. Ultimately, it will be these technologies and not MicroSort that is used, since whilst the latter has a 93% accuracy rate if a girl is desired (itself a lower result than genetic diagnosis), its accuracy falls to 82% for boys, and the vast majority of selections will inevitably be for males 1 . Thus, given that they are so keen to have a child of a particular gender and so unwilling to risk having one of the other gender, parents will not risk using MicroSort. Even if they do choose it, whilst there have not been overt problems thus far, scientific experts like Lord Winston express the fear that the process damages sperm, making genetic mutation much more likely. Both techniques are therefore to be condemned.  1. Genetics and IVF Institute. (2008, January 1). Microsort. Retrieved May 20, 2011, from Genetics and IVF Institute:
