Preimplantation genetic diagnosis is a valuable addition to the repertoire of reproductive medicine because it gives individuals with a documented history of a genetic disorder the opportunity to begin a wanted pregnancy with little or no fear that they are transmitting this disorder to their offspring. An outstanding example of this is the recent report of PGD being successfully used to avoid the conception of a child that could have inherited a predisposition to early-onset Alzheimer disease. However, if this service becomes embroiled in the detection of conditions having little or nothing to do with health and disease in order to satisfy patient demand or to be a profitable business, its activities will be much more ethically suspect.
植入前基因诊断是生殖医学领域一项有价值的补充技术，因为它让有遗传疾病记录史的个体有机会开始他们想要的妊娠，而几乎不用担心或完全不用担心会将这种疾病遗传给后代。一个突出的例子是最近有报道称，植入前基因诊断成功用于避免怀上可能遗传早发性阿尔茨海默病易感性的孩子。然而，如果这项服务卷入检测与健康和疾病几乎无关或完全无关的情况，以满足患者需求或成为盈利业务，那么其行为在伦理上就会更值得怀疑。
