After pregnancy, whether the pregnant mother is pregnant with a boy or a girl has always been the most willing topic for discussion during pregnancy. Many expectant fathers and mothers have their own preferences for the sex of newborns. I also hope to know the sex of my baby as soon as possible, and I am eager to know the sex of my baby in advance through some methods.
So just 50 days pregnant, how to judge the baby's gender?
First of all, it is necessary to identify the sex of the fetus.
Medically speaking, pregnant mothers can identify the sex of the fetus after 22 weeks of pregnancy through B-ultrasound examination. However, the law does not allow to preset the sex of the fetus at the beginning of pregnancy or in advance.
There are strict regulations and supervision on sex discrimination of infants not only at home but also abroad. Like France, which is far away from Europe, sex selection is forbidden except for rare genetic diseases. In Germany, gender identification is also prohibited unless there are some special reasons.
Second, the pregnancy check can show the sex of the fetus.
1, check the gestational sac during pregnancy. Pregnant mothers can observe the gestational sac in the uterus by ultrasound in the early pregnancy. You can also observe the gestational sac through the vagina and abdomen of the pregnant mother later. Others say that the shape of the gestational sac is related to gender, with long strips for boys and oval or round ones for girls.
But the fact is that due to the shape of the pregnant mother's uterus and the development of the fetal sac in the uterus, it is impossible for the early fetal sac to grow evenly in all directions, nor can it be round, and most of it will be oval.
Gestational sac will also be influenced by many other factors, such as uterine malformation, hysteromyoma, adenomyosis, embryonic development, and whether there will be abortion, which will make gestational sac have different shapes and states.
The sex of the baby can't be judged by observing the shape of the gestational sac, which is mainly related to the baby's chromosome.
2. Down's screening. Down's screening will be carried out in the first trimester and the second trimester respectively, and the results can be comprehensively evaluated through some indicators monitored in the blood of pregnant mothers. However, in Down's screening, the number of common autosomal abnormalities ranges from 800 1 to 0,000 1. The risk of Down's screening will increase with the age of pregnant women. Because of their age, they will be required to undergo other prenatal Down's screening, and the results of Down's screening during pregnancy will be different in different gestational weeks. There is no scientific basis for inferring the sex of a baby from the results of Down's screening. The fact is that it is possible for both men and women.
3. Judging the separation of renal pelvis. Kidney is an important organ of human body, which appears in pairs. It mainly produces urine and excludes metabolism in the human body. In the kidney structure, the renal pelvis is the first place to collect urine and transmit it to the bladder through the connected ureter. The renal pelvis has a certain width, which will be different with the change of gestational age. If the width of the renal pelvis is too large, exceeding 15mm, hydronephrosis will be formed. Therefore, it is also false to judge whether it is male or female simply by looking at the size of renal pelvis separation.
4, fetal heart monitoring to judge. The fetal heart is the baby's heartbeat. The baby's heartbeat starts from the original heart tube of the heart and lasts until the end of life. The beating frequency of fetal heart will be affected by many factors, and it will be slightly faster in the early life. In the second trimester of pregnancy, the normal fetal heart rate will be between 120 ~ 160 beats per minute, and the beating frequency will be uniform with little change. In the third trimester, the heart rate of the growing fetus is 1 10 ~ 160 beats per minute.
The fetal heart will also fluctuate with the change of fetal movement and will return to normal after a period of time. These can also be monitored by a professional fetal heart monitor, and it will be obvious that everyone's situation is different, and the change of fetal heart is not static. And these have nothing to do with whether it is a male baby or a female baby.
Key Tip: In order to better raise the next generation, it is not allowed to interfere with personal preferences and wishes in gender judgment. This is also to make the male-female ratio of school-age babies relatively moderate. As parents, we should pay more attention to how to give birth to a healthy baby. As long as you are healthy, boys and girls are the same.
