It is an indisputable fact that the older a couple is, the greater the chance of having a daughter. Because age will affect the physical quality of both men and women, the number of sperm in men will decrease with the increase of age. 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 be greatly improved.

Step 2 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 research on the influence of women's diet on their children before pregnancy, it is found that the ratio of male to female in Britain is 106 100, while the ratio of male to female born to vegetarian women is 85 100. This data shows that pregnant women who are vegetarian are more likely to have daughters.

At the same time, American researchers have found that food can swing the channels of female reproductive system 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.

3. Men exercise more.

If the man exercises more, he will consume a lot of energy and accumulate more acidic metabolites, such as lactic acid and cupric acid, in muscles and body fluids, so that the vitality of Y sperm that can give birth to boys is lost more and faster than that of X sperm, and the probability that the child born is a boy is greatly reduced. Therefore, if you want to have a girl, you should increase the amount of exercise and often do indoor manual labor to make the liquid slightly acidic, and eat more acidic foods such as rice, fish, meat and eggs every day.

4. Create an acidic physical environment

If you want 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 sour food, but refers to the imbalance of acid-base balance in the human environment. Daily acidic foods include: all meat, fish, dairy products (such as cream, ice cream, cheese and flavored milk), rice and wheat flour products, canned food, corn, protein, sour fruits, chocolate, drinks and vinegar.

5, pay attention to sex time and posture

It needs to be done two or three days before ovulation. Before, the woman had to use two spoonfuls of white vinegar and 1 liter of water, and then she could wash her lower body after stirring evenly.
