Is it reliable to have boys and girls?

Some people like boys, others like girls. The pictures of the Qing Palace and the Old Yellow Calendar handed down from ancient times have largely satisfied the expectations of men and women for the sex of the fetus. This is a belief, not the map of the Qing Dynasty and the old almanac as ancient methods to predict the sex of the fetus. So, is it reliable to have boys and girls?

Is it reliable to have boys and girls?

The rumor of the Qing palace map is a prediction of the birth of boys and girls during the Qing palace period. It originated from Zhouyi and was calculated according to the formula of Yin and Yang five lines of gossip. It has a history of more than 300 years. It was run by eunuchs of various dynasties for the use of kings, relatives and the state, and then slowly drifted to the people. In this table, 1~ 12 represents the month of pregnancy, and 18~45 represents the age of women. However, it should be noted that this table is based on virtual age. How useful is the Qing palace map in guiding the sex of the fetus? There are many ways to have boys and girls now, which shows that everyone attaches importance to having boys and girls. Therefore, it is necessary to introduce in detail how useful the Qing Palace Map is in guiding the sex of the fetus. Sex identification is prohibited in China, and only Hong Kong can do fetal sex identification. There are different comments on this forecast table on the Internet. Some people say that they want to arrange their pregnancy time through the prediction results of this table, while others scoff at this table, which can predict boys and girls. Director Ling said that the accurate way to identify the sex of pregnant women's fetus in medicine is to do B-ultrasound, or to do blood smear from pregnant women's capillary blood. It is highly accurate to identify the sex of the fetus by cytomorphology after staining, but medical institutions are forbidden to use ultrasonic diagnosis, chromosome detection and other technical means to identify the sex of the fetus, and it is forbidden to choose sex to terminate pregnancy unless it is medically necessary, Director Ling reminded. There is no scientific basis for these methods to predict boys and girls. Just have fun at ordinary times, don't be too serious, don't spend too much thought, I believe that a certain method may be counterproductive, and eating a certain food may lead to malnutrition. Couples should have a scientific pre-pregnancy examination before giving birth to avoid infertility and genetic diseases. Check regularly during pregnancy to avoid affecting the healthy growth of the fetus.

Characteristics of boys and girls

During pregnancy, the pregnant woman's body will have different degrees of pregnancy reaction, and the symptoms of pregnancy are also different. It is said that pregnant women have different characteristics of boys and girls, that is, pregnant women with boys and girls will show different characteristics, so pregnant women can refer to it here. Different characteristics of pregnant women giving birth to boys and girls;

1, early pregnancy (that is, the first three months of pregnancy), no morning sickness, giving birth to a boy; In the first trimester, you will encounter severe morning sickness and have a girl.

2, the baby's heart rate is less than 140 minutes, giving birth to a boy; If the fetal heart rate is at least 140 minutes, a girl will be born.

3, the areola color is relatively deeper, giving birth to a boy; On the contrary, give birth to girls.

4. The bulging belly looks like a full, tight and round basketball, giving birth to a boy; A bulging belly, like a big watermelon, is not as round as a ball, so a girl was born.

In fact, the above statement does not have enough scientific basis. First of all, morning sickness is due to the rapid increase of human chorionic gonadotropin (HCG) level in early pregnancy, which inhibits gastric acid secretion and reduces gastrointestinal peristalsis, thus affecting the appetite and digestive function of expectant mothers. Whether it is a boy or a girl, morning sickness can happen. The personal experience of many pregnant women also shows that the severity of morning sickness has nothing to do with the sex of the fetus. Secondly, it is not reliable to judge the baby's sex by the baby's fetal heart rate. This statement is only based on what we call "common sense", that is, for adults, men's heart rate is generally lower than that of women. The heart rate of a baby girl is higher than that of a baby boy, and this is only at birth. When they are both fetuses, there is no difference in the heart rate between male and female fetuses.
