      孕早期B超单看男女准吗

      孕早期B超单看男女准吗

      孕早期B超单看男女准吗?肯定是不怎么准确的。在孕早期的时候,胎儿的性器官还没有发育成型,根本无法判断出胎宝宝是男是女,通过B超单只能看出孕囊的情况,根据孕囊的大小判断胎宝宝是男宝还是女宝是没有什么科学依据的。

      孕早期B超单看男女准吗

      1、民间流传从B超数据中的孕囊大小可以看性别,其实并没有任何科学依据。孕囊的形状大小是由孕期时间、营养、着床位置、宫腔大小等多种因素决定的。

      2、每个孕妈的宫腔不同,孕囊的形状自然随着宫腔形状而不同,而且还与孕妇检查时的状况有关,例如有的孕妇由于憋尿时间较长,子宫被压得扁一些,孕囊的形状也看起来扁一些。

      3、另外,有的孕妇怀孕时精子和卵子的着床位置正当,有的位置会偏一些,导致孕囊形状也不同。

      4、所以说,从B超数据,看孕囊形状大小可知胎儿性别,这是老一辈流传下来的说法,孕妈可不要太当真了,一般除了从B超中能直接看到胎儿生殖器官外,其他的民间说法都只能作参考。

      孕早期b超单看男女的方法

      1、看孕囊:看怀孕40-50天时的B超单,观察孕囊的大小和形状就能看出胎儿的性别,孕囊形状是椭圆或圆形的是女宝宝,长条形的是男宝宝。

      2、看双顶径和股骨长:双顶径即胎儿的头部横直径,而股骨长则是胎儿的大腿骨长度,老一辈们的说法是,头大腿短的是男孩,即双顶径-股骨长>2,头和腿相差小的是女孩。

      孕早期B超单看男女是不准确的,只能够看到孕囊的大致形状以及在宫腔内的情况,通过孕囊的大小和形状判断男女,这是一种传言,孕妈妈是可以不必当真的,等到怀孕三个月后就可以通过B超判断出胎儿是男宝还是女宝了,这样的方法才是比较真实可靠的。
