The sex chromosomes of a man are XY (vs. XX for a woman).
The 23rd chromosome is the sex chromosome. It is either an X or Y (strictly male) chromosome. When the sperm and egg cells fuse, they combine into 46 chromosomes with either two X chromosomes or an XY pairing. If it is 2 X chromosomes, the zygote is a female.
