There are many people who are convinced that they can have a baby boy or a baby girl by following certain techniques such as making love at the right time and circumstances, or eating the right diet.
All eggs have 23 chromosome, and the 23rd chromosome is an X. All sperms have also 23 chromosomes, and 1/2 have an X for the 23rd chromosome, and 1/2 have a Y as the 23rd chromosome.
At fertilization, when the sperm joins the egg, the baby's gender is determined by whether the 23rd chromosome on the sperm is an X or a Y.
There are certainly many myths and some evidence out there to the contrary.
If you want to have a girl or boy, it certainly can’t hurt to try and to be happy with having a baby, no matter what the gender is.
