Expectant fathers and expectant mothers are always full of expectations for the baby in the belly, often fantasizing that the child is not white, tall or not, who looks like whom, of course, the most wanted to know is the baby's gender.
There are many ways to teach parents on the Internet to "judge" the gender of the fetus, for example, when doing the B ultrasound, vaguely ask the doctor whether the baby's legs are long, beautiful or not, whether the house should be prepared, and so on. Others, which have been passed down for many years, are said to be very accurate methods, such as:
Sour and spicy
This should be the most widely circulated sentence to judge the sex of the fetus, not only because people pass it on by word of mouth, but also often appear in various novels and TV series.
Expectant mothers suppress the secretion of stomach acid because after pregnancy, a hormone secreted by the placenta inhibits the secretion of stomach acid, resulting in poor appetite. The sour and spicy food can stimulate the appetite and is favored by expectant mothers, but this really has nothing to do with having children.
As long as the mother-to-be eats happily, what kind of food she wants to eat, there is no need to worry about it, like there is a pregnant mother next to me, she only ate spicy at that time, no spicy and not happy, and finally gave birth to a son.
It is a boy who has a slow fetal heartbeat and a lot of fetal movement
In general, the normal range of fetal heart rate is 110-170 beats per minute, and because girls are born with a slightly higher heart rate than boys, some people think that boys with slow fetal heart rates (below 140) will be boys, and vice versa, girls.
In fact, the fetal baby is in the mother's belly, and the fetal heart rate is no different, but it will change with the different gestational age.
And the fetal movement is even more unfounded: girls have a heroic and cool type, there are also gentle and quiet types; and boys also have a flying male type and a heroic and majestic type, so they are not lively boys.
Severe early vomiting is for girls and not severe for boys
How did this conclusion come about? Is it because everyone generally believes that boys can eat better than girls and have a better appetite?
The main reason for expectant mothers to always want to vomit in the first trimester is the stimulation of hormones in the body (human chorionic gonadotropin, or HCG for short) on the gastrointestinal tract and intracranial center. In addition, there are psychological factors such as anxiety and mental tension caused by pregnancy, which have nothing to do with the sex of the fetus.
The left side of the gestational line is for girls and the right for pregnancy line is for boys
The pregnancy line refers to a vertical line that most expectant mothers have in the middle of their stomach that runs through the entire navel. It is rumored that the left side of the pregnancy line is a girl and the right side of the pregnancy line is a boy.
The appearance of the pregnancy line is still due to the changes in hormones in the body of the expectant mother during pregnancy, which is actually a pregnancy reaction. With the increase of gestational age, the development of the fetus in the womb of each expectant mother and the position of the fetus in the womb are different, so the growth of the abdomen is different, and the trend of the pregnancy line is of course different.
Renal pelvis separation is for boys
Renal pelvis isolation refers to the fact that in the second or third trimester of ultrasound, the maximum anteroposterior diameter of the fetus's renal pelvis has exceeded the normal range, mainly to assess the severity of hydronephrosis.
And because in the epidemiological data of hydronephrosis, the incidence of boys in newborns is about 2 times that of girls (that is, 65% of the fetuses with renal pelvis separation), it is actually unscientific and unreliable to conclude that renal pelvis separation is a boy.
In addition to the above, there are also judged according to the state of the skin (it is boys who love long spots and acne), the shape of the abdomen (the tip of the stomach is a boy, and the round circle is a girl), and even the time when the husband and wife have intercourse, which are not credible.
Before the birth of the fetus, the most accurate way to judge the gender of the fetus is only one, that is, the B ultrasound, and the others are not reliable.
