What's e point of this question. N ur response to it makes it sounds like ppl want to do PGD solely for selfish reasons like creation of designer babies. In SG, PGD is strictly allowed for some recipients (must reach certain criteria, age, miscarriage history etc) who may do it to weed out embryos with bad chromosomes (can be extra or missing ones) only. U can't even test e embryos for gender. Unless u go overseas, find a fertility facility who can help u do IVF and then PGD and then design whichever way u prefer.
