What determines if the baby is a boy or girl?

Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).

Is it the egg or sperm that determines gender?

Your Baby's Development

Out of the 46 chromosomes that make up a baby's genetic material, only two — one from the sperm and one from the egg — determine the baby's sex. These are known as the sex chromosomes. Every egg has an X sex chromosome; a sperm can have either an X or a Y sex chromosome.

What is the probability of having a boy or a girl?

My general response is that it's a 50/50 chance that a woman will have a boy or a girl. But that's not exactly true – there's actually a slight bias toward male births. The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO).

What is the probability of having male offspring?

In most industrialized countries about 105 boys are born for every 100 girls, for a ratio of 1.05, known as the secondary sex ratio, or SSR; the primary sex ratio is the ratio at conception. This is often expressed as the percentage of boys among all births, or about 51.2 percent.
