科學(xué)破解生男生女的8個(gè)民間傳言(3)

傳言6：胎動(dòng)方式分男女

孕媽媽可以觀察寶寶的胎動(dòng)方式，如果肚子左邊動(dòng)是男孩，右邊動(dòng)是女孩。還有一種說(shuō)法是女孩的胎動(dòng)比有些柔和，是一個(gè)點(diǎn)，男孩的胎動(dòng)是一條線，總是是頻繁動(dòng)個(gè)不停。

科學(xué)破解：

這種說(shuō)法，完全沒(méi)有科學(xué)根據(jù)。胎動(dòng)位置的改變，可以有多種情況，例如胎兒可能正在變換姿勢(shì)，或因媽媽的坐姿或站姿令她感到不適而移動(dòng)；也可能因?yàn)閷殞毟惺艿搅藡寢尩那榫w而作出反應(yīng)在子宮內(nèi)移動(dòng)。這些都有會(huì)引起胎兒位置的改變，與胎兒性別無(wú)關(guān)。

傳言7：胎心率看男女

民間有說(shuō)法認(rèn)為，如果胎兒心跳在140左右，則是男寶，如果在150以上則多半是女寶。

科學(xué)破解：

胎心就是胎兒的心跳，正常的胎心率在120-160次/分。如今，確實(shí)有大量統(tǒng)計(jì)學(xué)資料表明，女胎的胎心率大于男胎，那么據(jù)此是否就可以將胎心率作為判斷男女的指標(biāo)呢？這個(gè)問(wèn)題早在20多年前就有國(guó)外的研究者思考并研究過(guò)了，在《使用胎心率等圍產(chǎn)期產(chǎn)婦指標(biāo)來(lái)預(yù)測(cè)性別》和《超聲胎心率與性別》這兩篇論文里，明確否定了胎心率可以作為判斷男女的指標(biāo)。

傳言8：胎盤(pán)的位置看男女

也有人說(shuō)，如果準(zhǔn)媽咪胎盤(pán)的位置在子宮的后壁，懷的大多是男孩，如果胎盤(pán)的位置在子宮的前壁，懷的大多是女孩。

科學(xué)破解：

這種說(shuō)法更多的源于老一輩的經(jīng)驗(yàn)之談。目前，暫時(shí)還沒(méi)有科學(xué)根據(jù)可以證明這一點(diǎn)。反過(guò)來(lái)思考，如果孕媽咪的胎盤(pán)既不在前壁也不在后壁，而是長(zhǎng)在側(cè)壁上，那又該怎么來(lái)判斷肚子里的是男孩還是女孩呢？
