Adjust the acidity and alkalinity of diet: the food itself is acidic and alkaline, which can affect whether a woman is pregnant with a man or a woman to some extent. If you want to have a boy, the woman needs to eat more alkaline substances, and the man needs to eat more acidic substances.
Regardless of gender, whoever is older will increase the chances of having a girl. This is because with the increase of men's age, the number of sperm will continue to decrease, and the alkaline secretion in women's uterus will also decrease with age. Science has proved that the lower the values of these two indicators, the lower the chance of having a boy. Therefore, if both men and women are young, healthy and sperm and eggs are in the best condition, then the chances of having a boy are greater.

Precautions:
1, avoid staying up late: Women often stay up late, which will lead to the disorder of biological clock and a series of endocrine dysfunction, which will further affect women's ovulation cycle and directly affect pregnancy. Men staying up late for a long time will affect androgen secretion, and the quality and quantity of sperm will decrease, thus affecting fertility.
2. Quit smoking and drinking: It is best to quit smoking and drinking three months before pregnancy. Alcohol and tobacco have a great influence on the quality of eggs and sperm. If you have a history of smoking and drinking for more than one year, it is best to quit smoking six months in advance.
3. Stay away from radiation: computers, mobile phones, printers, etc. They are all radiation sources, so you should pay attention to stay away from or avoid long-term contact during pregnancy. This kind of electromagnetic radiation affects human sperm and eggs, so men should pay special attention to it, because male chromosomes are fragile, and sperm are more sensitive to electromagnetic radiation, which is more likely to affect fertility.
