Is the stretch mark on the left a man or a woman?
Although folks often say that stretch marks on the left are more likely to give birth to boys, this has nothing to do with the sex of the fetus. The method of judging boys and girls by stretch marks is not desirable, and it has not been scientifically verified at all. Because stretch marks are determined by the nature of the individual's skin, not the sex of the fetus. The thickness and depth of pregnant women's stretch marks depend entirely on the amount of hormones secreted by the human body. Even after we lose weight or lose weight successfully, white patterns will appear on our stomachs or thighs. Therefore, pregnant mothers should never believe rumors, thinking that they can judge whether they are a boy or a girl by the situation of stretch marks.
Folk method of identifying boys and girls by stretch marks
1, look at the thickness of stretch marks.
Pregnant women with narrow stretch marks will give birth to boys and wide ones will give birth to girls.
2. Look at the position of stretch marks
Pregnancy line, a pregnant woman above the navel, is more likely to have a boy if she is obviously left, and a girl if she is obviously right.
3. Look at the width of stretch marks
There are more boys with thin pregnancy marks and more girls with thick pregnancy marks.
How to treat the pregnancy line and know men and women?
Let me briefly summarize the viewing method to observe the first expressions of fathers, which is true and accurate. It is strongly recommended that prospective fathers take a look and observe the changes in their expressions. This is very accurate, and 95% of mothers have verified it.
1. The lower part of pregnancy line's navel is thick and dark, and the upper part is a little shallower than the lower part, like a straight line, reaching the breast position. The probability of having a boy is 95%.
2. On the contrary, there is a great chance of having a baby girl.
Netizen 1203 Meimei: Mine is a thick straight line, not a male treasure.
Netizen frog prince: There is only a light line below the navel, and the baby girl is born naturally.
Netizen adanCC: It has grown to the heart, and the blood test is a boy.
Netizen 000qq735: My colleague is very accurate. That's how she views men and women!
The formation of pregnancy line is actually a pregnancy reaction. Because of the imbalance of hormone secretion during pregnancy and the aggravation of pigment, most pregnant mothers will produce stretch marks. People's abdomen already has this line, which belongs to the normal texture of the body, but when they are not pregnant, most of them are light. It will gradually darken in the middle and late pregnancy, and most of them will become shallow or disappear after delivery.
Further extension, pregnancy line is obviously to the left, and there are more boys in general; Obviously to the right, it is generally possible to have a girl. But these are different from person to person, not all pregnant mothers, but according to my statistics, the pregnancy line is indeed more accurate than other popular folk methods. These folk methods are unscientific. I hope pregnant mothers don't take it seriously!
How to scientifically judge whether the fetus is male or female?
1. Ultrasonic scanning: Ultrasound is a sound wave, which has no adverse effects on the fetus. The accuracy of the baby in March-April must be very high. When ultrasound is used to diagnose the sex of the fetus, the accuracy of male infants can reach more than 95%, while the reliability of female infants is only about 85%.
2, DNA blood test: pregnant women are diagnosed by B-ultrasound in eight weeks. Under normal circumstances, the sex of the fetus can be measured with an accuracy rate of 98%, which has no effect on pregnant women and fetuses.
3. Amniocentesis: it is mainly used to diagnose whether the fetus has chromosome defects or neural tube defects, and it is usually performed at 16 ~ 20 weeks of pregnancy. The accuracy rate can reach 99%, but the probability of abortion is 1%.
4. villus sampling: the sex of the fetus can be judged around 12 ~ 14 weeks of pregnancy, but it may cause abortion (3% ~ 5%), and may also hurt the fetus, resulting in deformity of its hands and feet.
