lol... it has to do with the number of chromosomes they combine. Some couples can only create boys and some only girls. However, ultimately it's the female that decides this. My mom was only able to get girls from my dad, I have 2 sisters but had a son by another man. And my dad had his boys by another woman. Kinda crazy but that's life. Again and again...lol Sorry Rhonda I've read that all fetuses are female for several weeks until a certain hormone kicks in that changes the sex to a male. So every human is female at conception. Men should be nicer to us...lol

Whether you have a boy/girl is determined at the moment your baby is conceived.One pair of the babys chromosomes,called sex chromosomes,determines the sex.Females have two chromosomes called x chromosomes.In males the sex chromosomes are different,one is an x the other is a y chromosome.It is the presense of the y chromosome that determines whether the embryo will develope as a male.Eggs contain only x sex chromosomes.Sperm may contain either x or y sex chromosomes.In other words,the sperm is what makes the baby male or female.

There is some Chinese believe, should there be 3 sons continuous, the fourth one will be a "girl" because "3" rifles brand. Should there be 3 daughters continuous, the fourth one will be a "girl" because four ladies make one table. How true ? Check and confirm with friends.

It's all random chance. There is no proof for a genetic tendency toward any particular pattern. What they get is essentially a roll of the dice if you look at it through a scientific view, or part of a greater plan if you look at a religious view.

there are myths about different ways of having either sex in using this position or that position. I really just thing it up to nature to choose I don't know if they work or not as I just wanted healthy sons or daughters.
