First, pregnant mothers with good memory are more likely to have boys.
This conclusion is that Canadian psychology professor Neil? Watson and his research team proposed it. They found that pregnant women pregnant with boys are less likely to forget than those pregnant with girls. They said: when investigating the influence of pregnancy on women's cognitive ability, they found evidence that pregnant women with boys perform better than pregnant women with girls in the detection of hearing, calculation and visual memory.
It is reported that Watson's research team conducted a follow-up survey and research on a group of pregnant women for as long as 18 months, from the time when pregnant women were just pregnant until a few months after they gave birth. During this period, the researchers gave them 8 related tests such as memory. The test results are surprising to find that those pregnant women who are pregnant with boys are obviously better than those who are pregnant with girls, and so are they after giving birth.
If the facts are true, then ANDY, who has a strong memory of numbers in the hit drama Ode to Joy, must be pregnant with a boy!
Second, the more difficult it is for pregnant moms to conceive, the easier it is for them to have boys.
Luc, an epidemiologist at Maastricht University in the Netherlands? Smiths led researchers to investigate 5283 women who had given birth, and found that 498 of them took more than a year to get pregnant, and the proportion of them who gave birth to boys was 58%; While those who are pregnant within one year are 5 1% more likely to have a boy.
Researchers believe that, from a global perspective, the birth rate of boys has always been higher than that of girls. This is because sperm with Y chromosome is smaller and more flexible, so it is easier to combine with eggs through cervical mucus. Previous studies have found that the viscosity of female cervical mucus varies from person to person, and the higher the viscosity, the less likely it is to get pregnant. Experts explain that although it is difficult for women with high cervical mucus viscosity to conceive, in a long period of time, sperm with Y chromosome is more likely to pass through the cervix and combine with eggs, so the chances of giving birth to boys are greater.
Seeing this, those of you who want to get pregnant but have no stomach movement can relax your snacks a little. Because, this may be because God wants to give you a smart and lovely boy doll, so he asked you to wait a little longer.
Third, pregnant mothers with husbands around are more likely to have boys.
American medical expert Karen? Through the research of 86,436 pregnant women, Dr. Norberg found that if the parents lived together all the time before the birth of the child, the probability of a mother giving birth to a boy was higher than that of a single mother 14%. Dr. Norberg's research shows that the baby's sex has nothing to do with parents' wishes, parents' age, education level, income and race, and the birth year.
As early as 1874, Charles? Darwin had found that the proportion of males in babies born out of wedlock was low; In modern times, research in Kenya also shows that in polygamous marriages, the proportion of sons born to wives is low. Not only that, in the past 30 years, the developed countries such as the United States, Canada and Britain have experienced an unexplained sharp drop in the proportion of male babies. It is worth noting that the same period is also the peak period for single mothers. The scientific community has been puzzled by these phenomena, and now Dr. Norberg's research provides some scientific explanations for these problems.
It turns out that a husband's more company helps to have a boy! If you want to be a man, spend more time with your wife!
Fourth, pregnant moms who eat more cereal before pregnancy are more likely to have boys.
According to China Radio International, scientists from the University of Exeter and the University of Oxford in the United Kingdom followed up 740 women's eating patterns. Ask them to provide detailed weekly diet before and after pregnancy, including food quantity and nutritional components, such as potassium, VC, VE, etc.
The study found that the proportion of women who have cereals such as cereal and cornflakes for breakfast is much higher than that of women who have daughters. Among the women who mainly eat high-energy breakfast during pregnancy, 59% gave birth to a boy. However, only 43% of women with non-cereal breakfast gave birth to boys.
Is whole grains really so good, and eating more grains helps to have boys? Experts believe that the results of this study further confirm the relationship between diet and fetal sex. Therefore, if you want to decide to have boys and girls, you should pay attention to the diet before pregnancy.
5. Aggressive women tend to have boys.
Researchers have found that strong, confident and enterprising women are more likely to have boys than docile women. Why? Because scientists have determined that the level of testosterone in each female egg is different, eggs with higher testosterone levels are more likely to give birth to male embryos. The content of testosterone in women has a great relationship with the strength of dominant personality. The higher the testosterone content, the stronger the general personality and the more enterprising people are.
Experts explain: this principle may be that the testosterone level in female mammals' eggs determines their recipients. Male? The degree of sperm. The higher the testosterone level, the higher the degree of approaching male sperm. So, if you want to have a boy, hurry and live hard!
Sixth, pregnant moms who are engaged in masculine occupations are more likely to have boys.
New research shows that engaging in masculine occupations such as engineers or accountants will greatly increase the chances of pregnant women giving birth to boys. The London School of Economics reached this conclusion through a survey of 3,000 people in different industries and published it in the Journal of Theoretical Biology. Satoshi, a psychologist at the University of Canterbury in New Zealand who led the study? Canazza Wa found that the ratio of male students to female students is 140 100 among the people who are engaged in masculine occupations such as engineers.
Experts believe that the content of testosterone in the uterus of women who are engaged in masculine occupations is high during fertilization, thus increasing the possibility that the fetus is male. So, female architects usually have boys?
7. Rich pregnant moms are more likely to have boys.
A recent study by American scientists shows that married women with well-off families and high educational level are more likely to have boys; Women from poor families and poor health are more likely to have daughters. The data shows that black American women with poor health and education are much less likely to have sons than white women.
Simply put, the reason for this situation is that women's adaptability and endurance are stronger than men's. In poor families, girls are easier to support than boys, which can be seen from the death of babies. Therefore, according to the theory of evolution, women in poor families will give birth to girls with higher survival rate. This view is also true in some other species such as insects, birds, sheep, pigs, dogs, minks, deer and so on.
Columbia university science says:? We find that young and well-off married women can afford boys more. For example, a mother with a college degree is nearly 0.6% higher than a mother without a college degree. ? Experts believe that healthy and strong women tend to have sons, which can ensure that their genes and families can be passed down from generation to generation. These strong boys are more adaptable to the environment and continue to reproduce than other thin boys. The sons born to sickly mothers are often very thin. Under the same conditions, their adaptability is weak, and they are prone to death in childhood. Therefore, in order to continue the family life, these weak mothers often give birth to daughters, because girls can live longer until they become mothers themselves.
Xiaobian actually disagrees with this statement. Because, many detailed hot moms also gave birth to daughters, right? For example, size S, Wu Peici, Gigi Lai?
Eight, pregnant moms who eat a lot are more likely to have boys.
This is good news for mommy who wants to have a boy! Scientists in the United States and Sweden have found that pregnant women eat a lot during pregnancy and usually give birth to a baby boy, and the baby boy born at the same time is heavier than the baby girl.
Rulla Tamimi, a famous medical expert at Harvard Medical School, said:? It is a common phenomenon that newborn baby boys are heavier than baby girls, which will help us to identify the sex of pregnant women during pregnancy. Tamimi and the researchers observed and studied 244 pregnant women in Harvard Medical School and karolinska institutet, Sweden for six months. Through the research, it was shown that the secretion of testosterone by the testicles of male children was the direct cause of the large food intake of pregnant women with male children. That is to say, pregnant women who eat a lot are more likely to have a baby boy.
Why? Experts explain: This is because pregnant women with baby boys consume more energy during pregnancy. The energy required is as high as more than 10% calories in the body and more than 8% protein. Pregnant women must absorb a lot of carbohydrates and animal and vegetable fats to supplement their energy. Therefore, pregnancy suddenly becomes edible, probably because you are pregnant with a baby boy!
