Why am I male?

Your biological sex is determined by your chromosomes, specifically the presence of a Y chromosome. If you have a Y chromosome, you are typically male. This is determined at the moment of conception when the sperm carrying the Y chromosome fertilizes the egg. Gender identity, on the other hand, is a separate concept that is not necessarily tied to biological sex.

The sex of a person is determined by the chromosomes they inherit from their parents. Each parent contributes one sex chromosome to their child. If the child inherits two X chromosomes (one from each parent), they will be female. If the child inherits one X chromosome from their mother and one Y chromosome from their father, they will be male.

The Y chromosome contains the male-determining gene, SRY. This gene triggers the development of male reproductive organs in the embryo. In the absence of the SRY gene, female reproductive organs will develop instead.

So, the reason you are male is because you inherited a Y chromosome from your father.
