Second, eat vegetarian food and sweets British scientists have found that pregnant women who are vegetarian are more likely to have daughters. Although there is no other study on the influence of pre-pregnancy women's diet on their children, it is found that the ratio of male to female in Britain is 106 to 100, but the ratio of male to female born by vegetarian women is 85 to 100. This data shows that pregnant women who are vegetarian are more likely to have daughters. At the same time, American researchers found that food can swing the female reproductive system pipeline through hormone action, making the "viability" of a certain sex embryo stronger. Therefore, the content of sugar and fat in women's diet has certain influence on the sex of the fetus. Women who love sweets are more likely to have girls.
Third, the acidic physical environment wants to have a girl. Women should avoid eating too much alkaline food, eat acidic food properly, and of course, don't eat too much acidic food, so as not to affect their health. Both men and women should pay attention to a balanced diet. It should be pointed out that the acidic food mentioned here is not a food with sour taste, but refers to the imbalance of acid-base balance in the human body's internal environment. Daily acidic foods include: all meat, fish, dairy products except fresh milk (such as cream, ice cream, cheese and flavored milk), rice and wheat flour products, canned food, corn, protein, sour fruit, chocolate, drinks and vinegar.
4. It is an indisputable fact that couples who have children late are older, and the chances of having daughters are greater. Because age will affect the physical quality of both men and women, the sperm count of men will decrease with the increase of age, and the older women are, the changes of physiological hormones will also reduce the alkaline secretion in the uterus year by year, and the chances of giving birth to girls will also be greatly improved. However, this method is not very recommended. After all, after getting old, the functions of the body are not as good as when you were young. You should pay more attention to it and you are more prone to miscarriage.
5. Stop sexual behavior three days before ovulation. Usually, on the day of ovulation, a woman's body will secrete a large amount of transparent mucus, which can prevent sperm from entering the uterus and only stay in the acidic vagina. It is not suitable for the growth of Y sperm in an acidic environment, which makes Y sperm eliminated and leaves X sperm. After the mucus in the uterus dissolves, X sperm can successfully combine with the egg to give birth to a baby girl. Because sperm has a life span of 3 days in the uterus, if you want to avoid fertilization on the day of ovulation, you must stop having sex 3 days before ovulation.
