There is no scientifically proven way to guarantee having a baby boy naturally. While various myths and old wives' tales circulate, there is no method, supplement, diet, or sexual position that can influence the sex of your baby. The sex of a baby is determined at conception when a sperm containing either an X or Y chromosome fertilizes the egg.
While many cultures and individuals have preferences for the sex of their children, it is important to remember that the sex of a baby is ultimately determined by chance. You have a roughly 50% chance of having a boy or a girl with each pregnancy.
While there may be slight variations in the global sex ratio, there is no natural way to influence the sex of your baby.
