VOA常速英语:Parenting of the Future? Pick an Embryo

A growing number of pregnancies begin like this, in a lab,where technicians combine egg and sperm in a petri dish to create an embryo.That around ten percent of reproductive age couples in the United States have trouble getting pregnant or carrying a baby to term and we don’t understand why that is.
越来越多的生命诞生于实验室中技术人员将卵子和精子在培养皿中混合，创造出胚胎。在美国，大约有百分之十的育龄夫妇有怀孕障碍，我们也不明白是为什么。
With increasing rates of infertility around the globe, researchers like Amanda Clarke are exploring new frontiers in reproductive technology.The University of California Los Angeles scientist and her team are working to convert human skin samples into eggs which would be fertilized by sperm.The process called in-vitro gametogenesis or IVG as so far worked only with mice.If the technology is proven to be safe and effective, then I think it should be used in specific cases as a way of being overcome, being able to overcome infertility.Not only could it address infertility, IVG would be a less medically invasive procedure for women than the current procedure for harvesting eggs.Go to a clinic, the man will give a sperm sample.The woman will give instead of eggs a little bit of skin sample, the cells in her skin will be turned into eggs, an unlimited supply of eggs,and then the eggs and sperm will be combined to make embryos.That means in theory parents could choose which embryo to make into a child based on the genetic analysis but not everyone expects parents to jump at the chance.
随着全球不孕率的增加，像阿曼达·克拉克这样的研究人员正在探索生殖技术的新领域。加利福尼亚大学洛杉矶分校科学家和她的团队正努力将人类皮肤样本转化为卵子，这些卵子可以通过精子受精。这个过程被称为试管配子，简称IVG。目前只在老鼠身上做过实验。如果这项技术证明安全有效，那我认为这应该应用到特定的案例中，来解决不孕不育问题。IVG不仅可以解决不孕问题，对于女性而言，其采卵程序也不像当前医学那样具有侵略性。人们到诊所里去，男人提供精子样本。女人会提供皮肤样本，而不是卵子。她的皮肤细胞可以转化成卵子，而且是无限量的。接着，技术人员将卵子精子结合，制造出胚胎。理论上说，这意味着父母可以根据遗传分析将哪个胚胎培养成小孩，但是不是每个人都希望父母有这样的机会。
Here in California where there are some people who would like to have a baby with as few problems as possible.There are many people in this state and in fact they’re the ones who are having most of the children who will tell you it’s in God’s hands.But even before researchers address safety concerns about testing IVG in humans,its potential is forcing a conversation about the ethics of parents selecting their offspring.
在加利福尼亚州，有些人希望自己孩子身上的毛病越少越好。实际上，这个州很多人有很多孩子，他们会告诉你这事是掌握在上帝手中的。但是，即使研究人员解决了试管配子应用于人类的安全问题，在那之前，人们也必须讨论父母选择后代的伦理问题。
