一般受精卵着床后排出的白带其实和平时没有太明显的区别，主要的可能就是白带会增多。然后颜色的话，和平时差别的，就是主要呈白色稀糊状或蛋清样粘稠，也是没有异味的。如果白带量变大还掺杂着一些血丝，并有淡淡的腥味，过了两天又恢复了，等到了经期过后，月经也迟迟没来，则有可能就是怀孕了。

受精卵着床一般都是悄无声息的，除了有少数孕妇会有生理性的着床出血和轻微的痉挛以外。着床成功后一般女性体温会下降，有些人会着床出血，敏感的人会觉得有酸痛的感觉，还有些人会有感冒的症状。当然也有些人会出现小腹有一点隐隐的痛和酸酸的感觉，以及乳房胀痛，乳头有触痛感等症状。

一般着床后一周就可以去医院查血hcg，就可以确认怀孕。所以说，在没有确认怀孕前，就可以通过以上那些症状来判断受精卵是否着床成功。

如果有一天，你可以选择生育一个小“爱因斯坦”，也可以生育一个智商普通的孩子，你会做出什么样的选择？据科学家预计，未来10年内，人类将可以使用试管婴儿技术选择“最聪明”的胚胎。

Couples undergoing IVF treatment could be given the option to pick the “smartest” embryo within the next 10 years, a leading US scientist has predicted.

据美国一名权威科学家预计，未来10年之内，做试管婴儿的夫妇将能够选择“最聪明”的胚胎。

Stephen Hsu, senior vice president for research at Michigan State University, said scientific advances mean it will soon be feasible to reliably rank embryos according to potential IQ, posing profound ethical questions for society about whether or not the technology should be adopted.

美国密歇根州立大学主管科研的副校长徐道辉（斯蒂芬·徐）说，科学进步意味着人类不久就能够对胚胎的潜在智商给出可靠的评分，这项技术是否应该使用将是一个深刻的社会伦理问题。

Hsu’s company, Genomic Prediction, already offers a test aimed at screening out embryos with abnormally low IQ to couples being treated at fertility clinics in the US.

徐道辉的基因组预测公司已经为在美国不孕不育诊所接受治疗的夫妇提供了一项检测服务，旨在筛查出智商异常低的胚胎。

“Accurate IQ predictors will be possible, if not the next five years, the next 10 years certainly,” Hsu told the Guardian. “I predict certain countries will adopt them.”

徐道辉对《卫报》记者说：“准确的智商预测是可能的，即使不是未来5年内，那么在未来10年内也肯定可以。我预计一些国家会采纳这项技术。”

The prospect of a new generation of genetically selected babies has prompted concerns about unintended medical consequences and the potential for deepening existing social inequalities. The science underpinning the claim that intelligence can be meaningfully predicted by genetic tests is also contentious.

新一代基因选择婴儿的前景引发了人们对于意外医疗后果和现有社会不平等可能加剧的担忧。基因检测能够有效预测智商的科学技术也引发了争议。

contentious [kn'tens]：adj.有异议的，引起争论的

Peter Donnelly, a professor of statistical science at the University of Oxford, said any such IQ predictions should be treated with “huge caution”, adding: “I have grave misgivings about it on ethical grounds. I think it’s a really bad idea.”

牛津大学统计学教授彼得·唐纳利说，应该“十分谨慎”地对待此类智商预测。他说：“出于伦理原因，我对此非常担忧。我认为这是一个非常糟糕的想法。”

Since the 1990s, couples undergoing IVF have been able to screen their embryos for mutations in single genes that cause serious diseases such as cystic fibrosis, as well as conditions like Down’s syndrome, caused by chromosome abnormalities.

“Maybe the bottom 1% embryo will grow up to be a great person … even be a scientist, but the odds are against it,” he said. “I honestly feel if we can calculate that score and find a real negative outlier there’s an ethical responsibility for us to report that.”

徐道辉说：“也许评分最低的1%的胚胎长大后会成为一个优秀的人……甚至成为一名科学家，但这种可能性很小。我真的觉得，如果我们能计算出这个评分，发现它低得十分异常，那么我们就有道德责任予以告知。”

The company projects that once high-quality genetic and academic achievement data from a million individuals becomes available, expected to be within five to 10 years, it will be able to predict IQ to within about 10 points.

该公司预计，在5至10年内，一旦100万人的高质量基因和学术成就数据可用，它将能够预测智商，误差在10分以内。

Hsu is reticent about whether screening for high intelligence would be ethically justified, saying: “Let me just decline to answer that at the moment.”

徐道辉不愿评论高智商筛查是否符合伦理标准，说“目前我拒绝回答这个问题”。

reticent ['rets()nt]：adj.沉默的；有保留的

In some countries, such as Singapore, there is likely to be a high level of public acceptance and demand for such tests, he suggested. “I think the overwhelming majority would say yes, absolutely, parents should be allowed to do that,” he said. “Before you write your piece, you might just want to think that a billion people on the other side of the world might have a different view.”

徐道辉说，在一些国家，比如新加坡，公众对此类检测的接受度和需求可能会很高。他说：“我认为绝大多数人肯定会赞成允许父母这样做。在你写这篇报道之前，也许应该想想地球另外一端的10亿人可能有不同的看法。”

Whether such tests will become available in the UK would depend on approval from the Human Fertilization and Embryology Authority (HFEA).

这种检测方法能否在英国实施将取决于英国人工授精与胚胎学管理局的批准。

“If the HFEA decides that it’s not right for the UK, I will respect that,” Hsu said, but predicted that “rich people from the UK will fly to Singapore” if they are unable to get the tests locally.

他说:“如果英国人工授精与胚胎学管理局认为这对英国不合适，我会尊重这个决定。”但他预测，如果英国富人无法在当地进行这项检测，“他们会飞到新加坡去做的。”

Some in the UK take the view that prospective parents have a right to access such tests. “I don’t think people should be deprived of that knowledge,” said Prof Simon Fishel, the founder of Care Fertility.

在英国，一些人认为未来的父母有权进行此类检测。生育关怀组织的创始人西蒙费舍尔教授说:“我认为不应该剥夺人们的这种知情权。”

Fishel questioned whether there is any ethical difference between picking an embryo ranked highest for IQ or sending a child to a private school. “What’s wrong with ranking an embryo if you can rank a child?” he said. “I think there are plenty of people who’d choose embryo Oxford [rather] than embryo A-level failure.”

费舍尔质疑挑选智商最高的胚胎和送孩子去私立学校之间是否存在伦理上的差异。“如果你能给孩子评分，那给胚胎评分又有什么错呢？”他说。“我认为有很多人会选择未来能考取牛津的胚胎而不是无法通过英国中学高级水平考试的胚胎。”

In practice, though, couples often have only a few embryos to choose from. And there are concerns about unintended consequences. For instance, there is some evidence linking higher polygenic scores for academic ability to higher likelihood of autism.

但实际上，夫妇们通常只有几个胚胎可供选择。此外，人们还担心会出现意想不到的后果。例如，有证据表明，学术能力的多基因得分越高，患自闭症的可能性就越大。

The technology is controversial, but that does not mean it will not gain acceptance in the future, Hsu said, drawing parallels with the reaction to IVF in its early days.

徐道辉说，这项技术存在争议，但这并不意味着它在未来不会被接受，这与早期人们对体外受精的反应类似。

“The IVF pioneers … were called monsters, Frankenstein doctors; it was predicted that these babies would have health problems,” he said. “I am actually reassured by that. IVF is completely normalized now. Everyone who is pointing their finger at [Genomic Prediction] now should go back and read those articles.”

他说：“试管婴儿的先驱被称为怪物，弗兰肯斯坦医生。当时人们预测这些婴儿会有健康问题。实际上，我对此很放心。试管受精现在已经完全正常化。现在，所有指责（基因组预测）的人都应该回去读读那些文章。”

在赣州人民医院做供卵试管成功率挺高的，在50%左右。不过每个患者的情况不同，且影响供卵试管成功率的因素也比较多，所以最终的成功率也会有所差异。而且做供卵试管婴儿，合适的卵源是很不容易等到的，因为目前国内供卵都很紧张，捐卵的人少，申请供卵的人多，因此做供卵试管可能要等3-5年左右的时间，随着时间推移，患者年龄的增加，也会使成功率降低。

赣州市人民医院生殖科拥有先进的医疗设备、规范的诊疗技术、强大的综合实力，现成功率在赣州试管婴儿医院排名中比较靠前，医院试管整体成功率也已达到国内先进水平。在该医院做供卵试管的成功率也不低，不过影响供卵试管成功率的因素有很多，特别是患者年龄，下面就为大家介绍一下年龄与供卵试管成功率的关系：

1.年龄在25岁到35岁的年轻患者，身体各方面相对来说是比较好的，除了卵巢功能，但是做供卵试管可以不考虑这一点，因为用的是别人的卵子，只要子宫内膜环境这些状态好，那么成功率就比较高，一般在50%左右；

2.35岁到40岁的患者，内分泌及子宫条件都相对年轻患者差一些，所以做供卵试管的成功率也会低一些，通常在30%-40%左右；

3.年龄大于40岁的患者，即使使用的是质量较好的卵子，但是男方年龄也大的话，精子质量就会比较差，加上高龄的原因，试管成功率就会很低，可能只有20%左右，甚至更低。
