在威海正规医院申请供卵做三代试管首先需要先准备好夫妻双方身份证、结婚证,然后携带这些证件去做术前检查,以确定女性患者是否存在供卵适应症。然后登记申请卵源,一般需要等待2-5年左右,有卵源后就进行取精、培养受精卵等步骤。将受精卵培育成囊胚后进行PGD或PGS筛查,选出没有问题的囊胚进行移植,移植后等待14天左右返院验孕即可。

威海是山东省辖地级市,目前威海试管婴儿医院仅有一家,即威海市妇幼保健院,但该院目前仅可申请供卵还未开展三代试管,所以如果需要供卵做三代试管只能选择去同省的山大生殖,下面是在该院做供卵三代试管的流程:

1.身体检查:一方面是为了提高成功率,另一方面是为了明确患者是否存在供卵适应症;

2.等待卵源:因为国内不允许建立卵子库,所以医院都是没有现卵的,一般需要等待2-5年才能获得供卵;

3.胚胎筛查:获得卵源后就可以进行取精、培养受精卵了,等其变成囊胚后,就可以用植入前胚胎遗传学诊断技术筛选好的囊胚移植;

4.胚胎移植:选出囊胚后,将其用移植管推入女性子宫内;

5.试管验孕:等待囊胚移植后的第14天就可以到医院抽血验孕。

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.

自上世纪90年代以来,接受试管受精的夫妇已经能够对他们的胚胎进行筛选,以发现单个基因的突变,这些突变会导致严重的疾病,比如囊性纤维化,以及染色体异常导致的唐氏综合征等。

chromosome ['krmsm]:n.染色体

Many other traits, including height, physical appearance, intelligence and disease susceptibility, are known to be partly heritable. But because the genetic component is spread thinly over hundreds or even thousands of DNA regions, it has previously been impossible to screen for these traits.

许多其他特征,包括身高、外貌、智力和疾病易感性,都被认为是部分遗传的。但由于遗传组分稀疏地分散在数百甚至数千个DNA区域,以前不可能对这些特征进行筛选。

In the past decade, as vast genetic databases have been established, this picture has changed. Through analyzing many genes, each making a tiny contribution, it has been possible to calculate what are called polygenic risk scores, which give a person’s likelihood of getting a particular disease or having a certain trait.

在过去的十年里,随着大量基因数据库的建立,这种情况已经发生了改变。通过分析大量基因,每个基因都做出了微小的贡献,就有可能计算出所谓的多基因风险评分,即一个人患某种特定疾病或具有某种特征的可能性。

polygenic[,pli'denik]:adj.多基因的

Genomic Prediction is the first company to take embryo screening into this grey area of risk forecasting, offering to alert couples if an embryo has an “outlier” score for risk of cancers, diabetes, heart disease, dwarfism or low IQ.

基因组预测公司是第一家将胚胎筛查纳入风险预测这一灰色地带的公司。如果胚胎在癌症、糖尿病、心脏病、侏儒症或智商低下等风险方面的评分“异常”,它就会提醒做筛查的夫妇。

outlier ['atla]:n.(统计)异常值

Prediction for IQ is not good enough to give a reliable ranking, but Hsu said that knowing an embryo has a low score could still be desirable.

智商预测目前还不足以给出可靠的评分,但徐道辉表示,如果一个胚胎的智商评分较低,人们可能还是很想知道。

“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。”

迫不得已选择试管婴儿时

早日成为妈妈

而取卵作为试管婴儿的重要一环

有什么注意事项?

下面一起来看看吧!

01

取卵术前注意事项

术前需调整好心态。取卵是整个试管婴儿过程中唯一对身体有微创的手术,手术时间多为10~20 分钟。

取卵时会有轻微疼痛感,属于可承受范围,且可选择用镇静麻醉药,无需过于紧张。

也无需过分在意取卵数量的多少,取卵多不代表卵子质量高。

值得一提的是,有需求的女性务必选择正规且有资质的医院进行手术。

02

术前准备

促排过程中保持生活规律,戒烟戒酒;

武汉全包代怀孕保密咨询|326z3_U9118_威海正规医院供卵三代试管的具体流程是怎

饮食均衡,勿暴饮暴食,更勿进食阿胶、蜂蜜等补品以及任何保健品,服用任何药物前需咨询医生;

武汉代孕需多少费用

停止注射促排卵药物,当日按医嘱准时、准量注射人绒毛膜促性腺激素HCG;

进入周期打针后,可多进食富含蛋白质的食物;

不宜从事重体力及剧烈运动,取卵术前4~5天避免性生活;

需静脉麻醉患者取卵前一晚12点后禁饮禁食(睡前可适量补充易消化食物,如粥、热牛奶、豆浆、面包、面条、鸡蛋等预防低血糖),非静脉麻醉取卵患者可进食,但避免流质饮食。

03

手术当日

取卵当日切勿化妆、戴首饰、留长指甲及涂指甲油,以便随时观察生命体征的变化;穿着轻便舒适的衣服及平跟鞋,取下活动性假牙、隐形眼镜等,体内如有植入物请提前告知;排空膀胱。

取卵前,医生会对阴道进行消毒和冲洗;取卵时首先进行探针穿刺,在B超探头固定一根长长的穿刺针,其尾部连接着负压吸引胶管,接着将B超探头置入阴道,借助探头上的针管依次抽吸卵巢内每一个卵泡内的液体,然后放入试管内;将试管内的液体倒入小圆玻璃皿内,并在显微镜下拣吸出卵子注入另一个培养皿里,等待催熟。

取完卵后会被医护人员送入观察室休息,

需多饮水多排尿,观察尿色,如发现异常请告知医生。

术后注意事项

取卵术后休息1~2小时,可适当进食,

期间可能会有头晕、恶心、呕吐等不适,多是因为麻醉引起的,稍作休息后即可缓解。

也可能有下腹轻微胀痛、阴道少量流血现象,都是正常情况,一般不需特殊处理。避免剧烈活动,以免发生卵巢扭转或破裂。

有明显不适,如进行性加重的腹痛、腹胀、头昏无力、阴道流鲜血、血尿等,请随诊。

在饮食方面,适量增加摄入鸡蛋、瘦肉、豆制品等高蛋白低盐食物和冬瓜、橙汁、鲫鱼汤等利尿食物,多吃蔬果,少吃辛辣、生冷等刺激性食物,以防腹胀和便秘;注意有无卵巢过度刺激综合征(OHSS)的发生,其主要表现为胃肠道不适、腹胀、呼吸困难及小便量减少等。

此外,取卵术后禁盆浴,可以淋浴,保持外阴清洁,防止感染;术后直至早期妊娠阶段避免性生活,确定未孕者可以正常性生活;避免膀胱过度充盈和急剧的体位变化,以防卵巢扭转,表现为突然腹痛、恶心、呕吐、肛门坠胀感等。

一般可于取卵术后3天或5天,到医院了解胚胎及移植情况。
