Among these significant advances has been the ability to alter the genetic constitution of eggs by pronuclear and nuclear transfer as well as by the introduction of specific cloned genes into eggs and embryos.

In the first study,doctors in Britain and Australia found that infants conceived with both straightforward test－tube methods and a more invasive technique called intra－cytoplasmic sperm in jection,in which sperm is injected directly into the egg,have an 8.6% risk of major birth defects－－including heart and kidney abnormalities,cleft palate and undescended testicles －－ compared with the 4.2% rate in babies made the old－fashioned way.

在第一篇研究报告中，英国和澳大利亚的医生们发现，直接的试管受精和通过更具侵入性的技术－－把精液通过注射直接与卵子相遇的方法而出生的婴儿，有8.6％存在着主要由出生造成的缺陷的危险性－－包括心脏、肾功能不正常、裂腭、男孩隐睾症等。而正常受孕出生的孩子这种现象的比率只为4.2％。第二个研究报告
