Is sex selection immoral?

BioNews - Is sex selection illegal and immoral?: The use of preimplantation genetic diagnosis for sex selection has proven extremely controversial in the UK, where the procedure is illegal unless medically justified to avoid producing a child with a sex-linked genetic disorder, such as Duchenne muscular dystrophy. One reason often given for the restrictions is the fear that the technology will be used mainly to select male embryos. Research from the US, where sex selection for 'social reasons' is legal, suggests that its most frequent use would be for 'family balancing', or to select a child of the opposite sex to those a couple may already have. . . . Sex selection via PGD for purely social reasons requires a healthy woman with no infertility problems to undergo IVF and to undergo the pain, expense and danger of egg collection and embryo transfer only for the purpose of choosing the baby's sex.
