Siwei is a little girl, but gave birth to a little boy, what does the so-called female turning man mean? In fact, it is through the "B ultrasound" test to detect the sex of the baby in the belly.
And "female to male", is the actual gender result, this kind of problem is not uncommon, whether it is female to male or male to female is very common.
For pregnant mothers, the gender of the child is always the most concerned topic during pregnancy. Although it is the same for both men and women, the fetal baby in the belly can clearly distinguish the gender when it is about four months old.
Experienced doctors can already identify boys and girls at three and a half months, and when doing the fourth dimension, it is generally between the twenty-second and twenty-sixth weeks of pregnancy that the child's xing organs have developed well.
Why is there still a reason for the reversal? I believe that pregnant mothers and fathers-to-be will definitely cry and laugh when they know!
1. Postural effect
The fetus is in the womb of the pregnant mother, and the result of the judgment will be affected by various postures. If you do a four-dimensional color timeout, the fetal baby's legs just clamped the important organs, then there is no gender organ, and the doctor is easy to misjudge that it is a girl.
Sometimes, the doctor uses the probe of the B ultrasound, will guide the child to roll left and right, just to see if it can be judged from a different angle, if it happens to block the important parts, it is easy to cause the doctor to misjudge.
2, the fetus baby is too naughty
The fetal baby is in the womb of the pregnant mother, and the umbilical cord is not only the channel for the mother to deliver nutrition to the fetal baby, but also the toy of the fetal baby. Babies especially like to hold the umbilical cord.
Therefore, in doing the four-dimensional color timeout, it will be because the fetus rolls left and right, resulting in how the doctor guides the fetus, the fetal baby refuses to turn its head and insists on facing the pregnant mother.
In this case, when the doctor distinguishes the gender, it is easy to treat the important organs as the umbilical cord of the fetus because they cannot see clearly, or misjudge the umbilical cord as an important organ of the child.
3, important organs happen to be blocked by the hand
Although the four-dimensional color ultrasound is an advanced function, it may be affected by amniotic fluid and tissue fluid, and some parts still cannot be seen clearly. For example, if the baby's ear is not screened, it is also because it is really difficult to see clearly.
Four-dimensional color timeout, although the doctor intends to observe the sexual organs of the fetal baby, but if the fetal baby is too naughty, covering the important organs with his hands, and the fingers of the fetal baby are more similar to the sexual organs, it is easy to have the problem of misreading and misjudgment.
Whether it is a four-dimensional color ultrasound or a more accurate DNA blood draw test, there is a certain error. Four-dimensional color ultrasound mainly relies on the doctor's own professional knowledge, combined with B ultrasound imaging to make judgments, there is a certain degree of subjectivity.
And the whole process also needs the cooperation of the fetus in the belly, so the best way is to go with the flow, if you want to use "testing" to confirm the true gender of the child.
In fact, it is very unnecessary, as long as you determine the health of the fetus and the pregnant mother, it is the most important thing to care about.
