The ova contains an X chromosome.
The spermatozoa can contain either an X or Y chromosome so it determines the sex of the child

The woman contains XX chromosomes. The male, XY chromosomes. The male determines the child, because each parent has to give one chromosome to the child, and the woman will always give an X, for obvious reasons. Whichever the male gives is by chance and determines the baby's sex.

The female will always give only an X chromosome. The male will give either X or Y, and hence, depending on which, if the combination is XX, the sex of the child will be female, and if the combination is XY, the sex of the child be male.
