A woman with a big thing on her body will give birth to a girl

According to a recent British survey, parents who are under long-term stress are more likely to have a girl. Survey results from the 1995 Japanese earthquake and the 9/11 attacks in the United States confirm this inference. In addition, families suffering from poverty also have a higher birth rate of girls.

The researchers also investigated abortions in California between 1989 and 2001 and found that when unemployment rose, the abortion rate for male babies also rose.

A plausible explanation for this is that stress during pregnancy would make it more likely that a male fetus would be miscarried. In contrast, research results show that frequent sexual intercourse is more likely to result in the birth of a boy, while less frequent sexual intercourse is more likely to result in the birth of a girl, and excessive stress is often an important factor leading to less sexual intercourse.

What factors affect the gender of the baby?

1. The day of sexual intercourse affects whether the baby is a boy or a girl. The vagina is usually acidic, but becomes alkaline near the day of ovulation. Considering the properties of X sperm and Y sperm, deliberately choosing the day of intercourse may achieve the effect of controlling gender to some extent.

2. Due to genetic influence, the birth of a boy or a girl often has a family tendency.

3. Affected by acid and alkaline environment. Y sperm is resistant to alkaline but not acid. In alkaline environment, Y sperm is active and easy to combine with eggs, while X sperm is active in acidic environment and easy to fertilize. Female athletes are more likely to give birth to girls, probably because after strenuous exercise, acidic substances such as creatinine and creatine in the blood increase, which is not conducive to the activity of Y sperm. Therefore, some people try to change the pH of the vagina to control gender. …Environmental changes determine whether a baby is a boy or a girl.

4. The influence of sexual life. Reduce the number of sexual intercourses, increase semen concentration and the sensitivity of sexual contact, choose the time for sexual intercourse during the ovulation period, fully increase the woman's sexual desire during sexual intercourse, let her reach orgasm and then ejaculate, it is easier to have a male fetus. Because the secretions of women during orgasm contain alkaline substances. On the contrary, frequent sexual intercourse and premature ejaculation can increase the chances of having a girl.

5. The influence of good or bad nutrition. Pregnant women who eat a lot are more likely to give birth to baby boys. Foreign scientists recently found that pregnant women who eat a lot during pregnancy usually give birth to baby boys, and baby boys are heavier than baby girls. Through a six-month observation study on 244 pregnant women, the researchers showed that the secretion of testosterone by the testicles of male babies is the direct reason why pregnant women with male babies eat a lot. In other words, pregnant women with a large appetite have a greater chance of giving birth to a male baby.

6. Influence of metal elements. Eating salty and potassium- and sodium-rich foods during the first 6 weeks of pregnancy can increase the chances of having a boy.

7. Seasonal influence. It is easier to conceive a boy in my country during the spring and autumn. More girls are born in summer and winter.

8. The influence of age. For every 5 years increase in the couple's age, the chance of having a girl increases by 1‰. If the husband is too old, the chance of having a boy decreases. There are more boys than girls born between the ages of 25 and 29, and more girls than boys born between the ages of under 25 and over 29.

9. Gender formation is related to the time of ovulation. The motility of X-type and Y-type sperm is different. Y-type sperm are smaller and more active than X-type sperm and swim faster in the female reproductive tract.
