据说 看B超单子可预知生男生女

发布日期:2024-07-07 05:18:55编辑:胖虎爱撩妹

  通过后台询问次数,也能知道不少爸妈都想提前知道宝宝的性别。
 
  不说重男轻女,提前知道性别也方便给宝宝准备东西。
 
  但可惜呀,国情规定一般情况下医生是不能透漏宝宝性别的,会违法。
 
  因此江湖传闻,干嘛需要医生说,自己看不就好了!
 
  看啥啊?怎么看?
 
  简答来说,就是看B超单子上孕囊数据的长宽相差和形状差异。
 
 
 
长宽相差
 
  ? 长和宽的相差在一倍以上男宝宝可能性大
 
  ? 长和宽相等女宝宝可能性大
 
 
 
形状差异
 
  ? 像茄子或长条状的是男宝宝可能性大
 
  ? 圆圆的是女宝宝可能性大
 
 
 
  另外,附送5个供参考的B超数据:
 
  ? 5周6天,孕囊大小:25*11mm,男孩
 
  ? 7周1天,孕囊大小:29*19mm,男孩
 
  ? 7周多,孕囊大小38*23mm,男宝宝
 
  ? 8周,孕囊大小:41*28mm ,女宝宝
 
  ? 9周4天,孕囊大小:46.6*30.2mm,女孩
 
  在这广泛基础上,许多孕妈根据经验,进一步建议:
 
  ? B超数据不能超过8周,40多天是最合适的
 
  ? 最好要有3个数据
 
  因为2个数据的话,看不准确。
 
  每个B超师获取孕囊的方位不一样,所以不能判断,有3个数据的,是最好判断的。
 
  举例:
 
  如果孕囊成等差数列,比如40*30*20,这样就是女孩。
 
  而如果两个数据差不多,第三个数据比前两个小一倍,那肯定是儿子,如果成递减数据就是女儿。
 
 
 
  到底,孕囊看胎儿性别靠谱吗?
 
  ? 孕囊数据其实是用来测算孕龄
 
  孕囊大小,主要是用来估算孕龄,根据数据的变化,能及时察觉胎儿发育中的缺陷。
 
  孕囊数据因人而异,而且也是因时间不同而异。
 
  一般孕妈在孕五周的时候会做一次B超,根据B超的情况判断怀孕了多久,而且通过看胎囊是否偏小去看胎儿是否健康。
 
  ? 孕囊形状不同有很多原因
 
  其实,孕囊形状跟胎儿性别真没啥关系……
 
  绝大多数胎囊都是圆形或者椭圆形的,变不出其它形状。
 
  而且,孕囊形状由宝宝的大小和羊水的多少决定,是会自行改变形状的。
 
  所以,不用把孕囊形状和胎儿性别联系在一块了。
 
  
 
  还是那句话:胎儿性别从精子和卵子结合的那一刻就决定了。
 
  所以,许多江湖传言酸男辣女、肚尖男肚圆女、孕囊大小等方法其实都不能判断男女的。
 
  终归一点,只要宝宝健康,是男是女又何妨。 老公是女儿控,希望生个前世情人,保护她呵护她爱惜她;而我更是个女儿控,特别想生个女儿,给她扎小辫子穿花裙子打扮成美美哒公主;一胎已有男宝的家庭,更是迫切希望生个女娃凑成一个“好”字……
 
  如今,越来越多的人已经没有重男轻女的思想了,生个女儿也是很多人的心愿。不少新爸新妈只要一有空就开始研读各种生女宝典,还各种拜师学艺求取生女真经……辣么,要如何圆这个女儿梦呢?
 
想怀女孩 这些方法你必须知道
 
啊
 
  虽然说生男生女是随机的,但是有些影响因素还是可以起到一定的作用呢。以下为你介绍一些生女孩的小“秘方”,想要怀女宝的准爸准妈们,赶紧来学习技能吧。
 
  -01-
 
 
  ▼
 
  (1)排卵期3天之前同房
 
  我们知道,在排卵期同房才能怀孕。因此,准妈妈想要一击即中,可以提前预测排卵日。如今有很多备孕APP,可以帮助你记录每个月的排卵期,准妈妈们只要把每个月的经期周期和来月经时间确定好,app会自动帮你计算出下个月的排卵期,这样一来,每个月哪几天处于排卵期就一目了然啦。在排卵前,宫颈粘液通常水润有弹性,与生蛋清类似。薛德斯建议在排卵期3天之前性交能够提高怀女孩的几率,憋问我为什么,这是科学家们的研究结果,值得一试。
 
  (2)每天早晨测基础体温
 
  月经周期中,排卵以前的基础体温常较低,正常每日清晨起床前的体温(即基础体温)在37度以下,约在36.4-36.6度左右。排卵时体温稍下降,排卵后体温平均上升0.5度左右,一直维持到月经来潮前才开始下降。薛德斯建议每天早晨起床前量体温,尽可能小心保持平躺,任何运动都可以会给出不准确的读数。
 
  (3)监控性交的频率与时间
 
  薛德斯方法的理论基础就是Y染色体(男孩)精子较小并且不够强壮,但移动速度比较大的X染色体(女孩)精子快。也就是说,想要生女该,可以在距离排卵期远的时间性交,这样有助于为移动慢的X(女孩)精子带来优势,增加生女孩的几率。
 
  (3)避免女性达到性高潮
 
  在浅口处性交能让精子更有可能停留在阴道入口处,该处比宫颈处的酸性更高。该理论是酸性能够削弱Y(男孩)精子,从而让更多的X(女孩)精子更够接触卵子授精。这个理论告诉我们,尽量在同房时采取浅插入的姿势,尽量避免女性达到性高潮,让射出的精子在酸性的阴道内停留一段时间,让Y精子被自然淘汰,只留下X精子。
 
  推荐的姿势:侧卧体位、伸长体位、骑乘体位、后侧体位。

  想要生女儿,在饮食上有哪些技巧呢?有科学家已经做出一些研究了,虽然可行性还没得到广泛支持,但是新爸新妈不妨来了解一下,说不定就一击即中了呢?!
 
  吃大量的钙和镁。富含钙和镁的饮食可能会增加母亲的碱度,这可能对男性精子不太有利,也就是说生女孩的概率升高了。那么,哪些食物富含钙和镁呢?
 
  富含钙的食物:牛奶、奶酪、鸡蛋、豆制品、海带、紫菜、虾皮、芝麻、山楂、海鱼、蔬菜等。
 
  富含镁多的食物:小米、荞麦面、黄豆、蚕豆、豌豆、冬菇、紫菜、桃子、桂圆、核桃、花生、裙带菜、洋栖菜、芝麻(黑芝麻)、紫苏、糙米等。

  生活习惯
 
  ▼
 
  (1)让老公多点运动
 
  孕育一个健康的孩子,需要夫妻双方有一个健康的体魄。不妨开始锻炼吧,特别是老公,如果男方运动量很大,使肌肉和体液中积累了较多酸性代谢物如乳酸、铜酸等,则生女儿的几率会大于生儿子的几率。当然这只是一个观点,最重要的还是要锻炼使得身体健康,为孕育一个健康的宝宝做准备啦。
 
  (2)让老公戒烟戒酒
 
  不管是生男还是生女,都需要有一个良好的身体素质,戒烟戒酒是最基本的,希望准爸们都可以努力做到这一点。因为烟酒都有可能导致胎儿畸形,虽说有一定的概率性,但是最好还是戒了吧。
 
  (3)夫妻一起提前吃叶酸
 
  备孕期间,准妈妈可以开始吃叶酸,每天补充0.4mg就行,一般就是一天一颗药片,准爸爸也可以跟着吃哦。叶酸对于预防新生儿畸形有很大的帮助,可以从孕前3个月开始吃到孕期前三个月,也就是一共吃六个月的时间。
 
  【编辑有话说】
 
  其实,生男生女只是一个概率性的问题,有50%的几率生男孩,也有50%的几率生女孩,虽然坊间有很多生女的偏方,但是理论上说得通,实践起来也不是100%准。与其去偏信那些不科学的偏方,还不如老老实实科学备孕,做好一切准备生个健健康康的娃才实际点你说是不是?!
