Can you have a girl if you have sex before ovulation?

First of all, we need to make it clear that whether a boy or a girl is born is determined by genetic genes. These genes are located on chromosomes, and each chromosome carries specific genetic information. During fertilization, the sperm and egg combine to form a fertilized egg. The combination of chromosomes in this fertilized egg depends on the female X chromosome and the male Y chromosome, so whether you have a boy or a girl is determined by the combination of these two chromosomes.

So, can having sex before ovulation increase the chance of having a girl? Some research suggests that scheduling sex before ovulation can increase a woman's chance of conceiving a girl. However, this statement is not widely recognized by the scientific community and has not been rigorously confirmed.

In addition, some people believe that arranging sex before ovulation can increase the probability of conceiving a girl because the chromosome combination in the fertilized egg is more biased towards the girl's gender. However, this claim has not been scientifically proven either.
