B超看男女有看錯(cuò)的嗎 B超看男女你不知道的那些真相(2)

B超看胎兒性別也會(huì)出錯(cuò)的，原因：

1、胎兒體位誤導(dǎo) 跟孩子的體位等各種原因都有關(guān)系的，因?yàn)槭峭ㄟ^(guò)影像資料顯示的，所以可能是有錯(cuò)誤的。

2、胎兒小 胎兒發(fā)育尚小的時(shí)候是不能看出性別的。

3、月份漸長(zhǎng) 六個(gè)月以上的話就比較難看了，因?yàn)閷殞毣顒?dòng)力比較強(qiáng)，看的位置比較難確定。

4、和醫(yī)生的水平有關(guān)：是否準(zhǔn)確取決于B超醫(yī)生的專業(yè)水平，這個(gè)很重要；

B超鑒定胎兒性別的原理：

超聲在人體內(nèi)傳播，由于人體各種組織有聲學(xué)的特性差異，超聲波在兩種不同組織界面處產(chǎn)生反射、折射、散射、繞射、衰減以及聲源與接收器相對(duì)運(yùn)動(dòng)產(chǎn)生多普勒頻移等物理特性。 醫(yī)學(xué)上，應(yīng)用不同類型的超聲診斷儀，接收這些反射、散射信號(hào)，從而顯示各種組織及其病變的形態(tài)。

當(dāng)超聲遇到寶寶的生殖器時(shí)，會(huì)影像出它的”形態(tài)”，從而判斷是男是女。也就是說(shuō)，直觀的“看到”寶寶的外生殖器。

小編的話

B超看男女是可能看錯(cuò)的，和胎兒的體位、月份大小以及醫(yī)生的水平有關(guān)。一般情況下，如果醫(yī)生檢查說(shuō)是男寶，那么十有八九就是男寶的了，如果醫(yī)生檢查說(shuō)是女寶，還是有可能翻盤成男寶的。不過(guò)，小編個(gè)人認(rèn)為沒(méi)有必要去檢查胎兒性別，生下來(lái)就知道啦！
