The advent of the polymerase chain reaction technique has revolutionized the science of prenatal diagnosis including sex selection. The technique is now available to identify the sex of human preimplantation embryos after in-vitro fertilization or to determine the sex of a fetus by non-invasive methods. Where medical indication exists, selected female embryos can be transferred to the uterus and thus prevent unnecessary termination of an established pregnancy. However, these methods might be used for non-medical purposes as well. The developments in this field which have occurred during the last decade, as well as the moral dilemmas which accompany these advantages, are discussed in this paper.
聚合酶链反应技术的出现彻底改变了包括性别选择在内的产前诊断科学。现在可以使用该技术在体外受精后鉴定人类植入前胚胎的性别，或通过非侵入性方法确定胎儿的性别。在有医学指征的情况下，可以将选定的女性胚胎移植到子宫，从而避免不必要地终止已确定的妊娠。然而，这些方法也可能被用于非医学目的。本文讨论了过去十年该领域的发展以及伴随这些优势而来的道德困境。
