Clinically speaking, there is no such thing as how to have a boy, and no medication or food can change the sex of the fetus.
Medically speaking, whether or not you can have a boy has a lot to do with the chromosomes provided by the father. Usually the male sex chromosome is XY and the female sex chromosome is XX, and a boy is formed only when X and Y are combined.
Whether you have a boy or a girl is not very important, as long as you have a healthy and smart baby, that’s all that matters. Couples should pay attention to rest, avoid staying up late, prohibit smoking and alcohol, improve the quality of sperm and eggs, and do a good job of preconception checkups as well as pregnancy checkups during the preparation period.
Having a boy is not something that can be controlled by human beings. During pregnancy, it is recommended to pay attention to rest, balanced nutrition and regular pregnancy tests. If abdominal pain or vaginal bleeding occurs, it is recommended to go to the hospital in time.
