There are biological reasons why there are slightly more boys born every year than girls. The 'natural' sex ratio at birth is around 105 boys per 100 girls (ranging from around 103 to 107 boys). In some countries, the sex ratio at birth is much more skewed than would occur naturally.

It's all about Dad's genes That's with the assumption, though, that the man's sperm carries equal numbers of X and Y chromosomes. A man's X and a woman's X combine to become a girl, and a man's Y combines with a woman's X to become a boy.

Being a boy or a girl, for most children, is something that feels very natural. At birth, babies are assigned male or female based on physical characteristics. This refers to the "sex" or "assigned gender" of the child.

A child's biological sex (male or female) is determined by the chromosome that the male parent contributes. Males have XY sex chromosomes while females have XX sex chromosomes; the male can contribute the X or Y chromosome, while the female must contribute one of their X chromosomes.

Sex assigned at birth or biological sex is the label a medical professional gives a baby when it is born. This assignment is usually based on what a doctor observes about a baby's body. Babies born with es are labeled male, and babies born with vulvas are labeled female.

In the United States, most people are assigned both a biological sex and gender at birth based on their chromosomes and reproductive organs. However, there is an important distinction between biological sex and gender. Biological sex, such as male, female, or intersex, commonly refers to physical characteristics.
