Dear Mythili, The ability to choose the sex of your baby before conception is currently achieved only through couples using in vitro fertilisation to get pregnant. In Australia, sex determination is only considered when there is a genetic defect carried on the X chromosome which will cause severe disease in the baby if it is a male. The advantage here is that only embryos who will not suffer from the diease are implanted (the females) but the drawback is that not all the males will actually be carrying the defective chromosome but none will be given the chance to be implanted and grow into a fetus. I have answered this question from a medical perspective because this is a scientific website. Obviously there are also ethical reasons against sex determination.
