It is the sperm from the male determines the sex of the child. Half of the sperms contain the Y chromosome and half the sperms contain the X chromosomes. Ovum from the female always contain the X chromosome. When the sperm with Y chromosome fertilize the ovum, the sex of the child becomes male. When the sperm with X chromosome fertilize the ovum the sex of the child becomes female. The females are wrongly blamed for the birth of female child in some countries.

A woman's eggs all contain X chromosomes, so the mother always contributes an X chromosome to the baby. A man's sperm, on the other hand, contains a mix of X and Y chromosomes. What determines the sex of the baby is whether the woman's egg is fertilized with a sperm carrying an X chromosome (baby has XX and will be a girl) or with a sperm carrying a Y chromosome (baby has XY and will be a boy).
