另一个胎儿哪去了？医生说被胎盘或母体吸收 Another fetal which go to？The doctor said was the placenta or maternal absorption

　　这事其实很常见，很多早期妊娠都是双胎，竞争中优胜劣汰 It is very common，Many early pregnancy is double child，Weeds out the competition

Clearly a B to exceed according to twins，How had 18 days turned into single quadruplets，First pregnancy yellow lady was done“dizzy”the。

　　另一个胎儿哪里去了？有医生说“被吸收了”，有的说“凋亡了”，总之情况“很正常”。

Another fetal where？A doctor said“Is absorbed”，Some said“Apoptosis the”，In all circumstances“Very normal”。

　　这些回答都无法拉直她脑中的问号，丈夫和婆婆也为意外失去一个孩子伤心不已。

　事隔18天 双胞胎变单胞胎 After 18 days twins change single quadruplets

　　昨天，29岁的黄女士在武汉一家网站论坛发贴，今年5月26日发现怀了孕，一家人很高兴，老公“舌头都捋不直了”。夫妻俩双方家族都有双胞胎基因，还猜测会不会怀上双胞胎。

yesterday，29 years old lady a website in wuhan yellow BBS to post，May 26, this year found that conceived，Family are very happy，The husband“Le tongue is not straight”。Both the husband and wife both families have twins genes，Even suspected will bear twins。

　　怀孕40天，到武汉同济生殖医学专科医学查血，HCG值(人绒毛膜促性腺激素)水平很高，医生分析宝宝发育很好，还可能是双胞胎。10天后去复查，检查结果是“双胎囊双原始心管搏动”，局部有液性暗区。医生建议住院，后来在家休养。

Pregnant 40 days，To wuhan tongji reproductive medicine specialist medical checks blood，HCG value(Human gonadotropins)Very high level of，The doctor analysis baby development is very good，May also are twins。After 10 days to review，Check the result is“Double tire capsule double the original heart beats tube”，Local have liquid of the dark areas。The doctor suggested in hospital，Later to rest at home。

　　18天后，忐忑的黄女士又挂了协和医院专家号，专家对照此前B超发现，两个宝宝在一个胎囊里，情况不太好，建议再重照。结果让她惊呆了——只有一个胎儿了。

18 days，The lady was yellow hung again ZhuanGuHao xiehe hospital，Experts had found B (contrast，Two babies in the womb in a capsule，Not so good，Suggestions according to their。The results make her startled--only a fetus。

　　黄女士难过极了。如果说孩子“流掉了”，为何没有腹痛、出血或排出异物？

Ms wong so sorry。If children“Flow off”，Why no abdominal pain、Bleeding or foreign body eduction？

　　网友们也七嘴八舌：“你们怕不怕曾经也吸收过自己的弟弟或妹妹，太恐怖了！”“万一宝宝多个手脚或多个器官怎么办？”

Users also conflicting views：“You scared ever also absorb the brother or sister，scary！”“One thousand baby more hands and feet or more organs？”

　两个胚胎互相竞争，优胜劣汰 Two embryos compete with each other，Superior bad discard

　　记者向同济、协和、商职等多家医院妇产科求证，专家们说，这种情况的确很常见。一年都会遇到几例到数十例。

A reporter from tongji、union、As business and a number of obstetrics and gynecology hospital verification，Experts say，This kind of situation is common。A year will meet a few to dozens of cases。

　　湖北省生殖医学会主任委员、同济医院妇产科教授朱桂金说，“单胎流产率也有17%左右，双胎当然也可能流掉一个，甚至两个。”很多早期妊娠是双胎，在发育过程中，两个胚胎互相竞争，优胜劣汰，较弱的那个就停育了，这是自然筛选的过程，是正常现象。

Hubei province reproductive medicine the chairman of the committee、Tongji hospital professor of obstetrics and gynaecology ZhuGuiJin said，“Single tire abortion rate also has 17%，Double tire of course also may flow off a，Even two。”Many early pregnancy is a child，In the development process，Two embryos compete with each other，Superior bad discard，The relatively weak that will TingYu......，This is the natural selection process，Is normal phenomenon。

　　“以前没有这么多检查手段，大多数没被发现。现在发现的也只是较小的一部分，早期被淘汰的双胎之一很多，大部分留下的单胎仍然平安无事，黄女士不必过于忧心。”朱桂金说。

“Before so many inspection method，Most was not found。Now will only be found part of the smaller，Early be eliminated one of the double tire many，Most of the single tire still left in peace，Ms wong need not too concerned。”ZhuGuiJin said。

　　朱桂金解释，一般来说，由一个卵子分裂出的单卵双胎极少发生这种情况，这类胎儿要么都健康发育，要么同时出现问题。“自然减胎”多发生在双卵双胎和试管婴儿上：一个胎儿发育正常，另一个却“消失”了，原因很复杂，染色体异常是主要原因，发生率约占60%以上。

ZhuGuiJin explain，Generally speaking，By a single egg splits the eggs double tire rarely happen，This kind of fetal either all health and development，Either and problems。“Natural reduce child”Occurs in double eggs double tire and test tube babies：A fetus，The other one was“disappear”the，For reasons too complicated to，Chromosome abnormality is the main reason，Rate of about 60% above。

　　而孕早期消失的胎儿，常常被胎盘或母体吸收，剩下的一个或多个胎仍可以正常发育，母亲不会出现不适，不会出血或排异物，所以黄女士无异样的感觉是正常的。

Early stages of pregnancy and the disappearance of the fetus，Is often the placenta or maternal absorption，The rest of the one or more child can still grow normally，Mother won't appear discomfort，Won't bleeding or platoon foreign body，So ms wong no unusual feeling is normal。

　是否双胞胎 12周后做B超 If twins 12 weeks doing B to exceed

　　难道是之前的医生看错了？针对网友的这一怀疑，武汉市十一医院B超室主任任叶青认为，一般来说，B超检查“可能看漏，不会看多”，怀孕50天以上可以看得清楚，黄女士“双胎囊双原始心管搏动”说明是双卵双胎，但存在自然淘汰的可能性。他平均一年也见过十来个这样的病例。

Is it the doctor before wrong？According to the net friend suspicion，Wuhan 11 B (RenYeQing leadership that hospital，Generally speaking，B ultrasonic examination“May be overlooked，Won't see much”，More than 50 days pregnancy can see clearly，Ms wong“Double tire capsule double the original heart beats tube”That is double eggs double child，But there is the possibility of natural selection。He also saw an average year ten such cases。

　　国外有研究报道称，在早期B超诊断出的双胞胎妊娠中，大概有1/5后来会消失。很多医生会提醒孕妈妈，如果在怀孕头几周发现怀上双胞胎，不要过于激动，等怀孕12周以后再做B超时才能确定。

Abroad have researchers report，In the early diagnosis of B (a twin pregnancy，About 1/5 later will disappear。Many doctors would remind pregnant mother，If in the first few weeks of pregnancy found pregnant with twins，Don't get so excited，And after 12 weeks pregnant again doing B to determine the overtime。

　　专家还举例说，有一种“纸样儿”就是接近孕中期胎儿，由于不断受到另一正常妊娠胎儿羊膜囊的挤压，死胎部分软组织被吸收。等到母亲分娩时，胎儿就变得又扁又薄，像纸一样，但轮廓却清晰可辨。这和我们常见的自然流产一样，是胎儿在宫内停止发育所致。

The experts also for example，There is a“Paper looks”Is close to the middle with children，Due to a fetus by normal pregnancy amniotic membrane extrusion of the capsule，Part of the soft tissue absorbed stillbirth。Wait until mother childbirth，The baby made flat and thin，Like paper，But outline is legible。This and we common natural abortion，Fetal development stops in the house is the result of。

　　值得注意的是，在妊娠3个月后发生双胎之一消失，母体和胎儿发生各种并发症的风险大大增加，孕妈妈应严密观察，以防并发症的发生。（记者祁燕 通讯员聂文闻 邱琼）
