The purpose of this article is to ascertain and appraise the ethical issues 
inherent to the utilisation of preimplantation genetic diagnosis for gender 
selection in infertile patients anticipating undergoing a medically indicated 
assisted reproductive technique procedure. Performance of preimplantation 
genetic diagnosis per request specifically for gender selection by an infertile 
couple undergoing medically indicated assisted reproductive technique may not 
breach the principles of ethics, and is unlikely to alter the population balance 
of sexes.
