During the first stages of life, a sperm from the male and the egg from the female merge together to create a zygote which turns onto an embryo which turns into a fetus which turns into a baby.

Now, the egg is always an X-Chromosome (Female) but the sperm can be either X or Y (Male). So it is the male who actually chooses the gender of the child.
