Who Makes Gender?

Sperm
Men determine the gender of the baby. Boys have chromosomes X&Y and girls have X&X. The Y chromosome determines that the fetus will be a male and only men have a Y chromosome. SO, men determine the sex of the pregnancy. In cases of a single X chromosome, called Turner Syndrome, the child is female. For gender selection, we sort the sperm or test the embryos for the Y chromosome.

Sperm
Males are made up of a total of 46 chromosomes (packages of DNA), and two of those determine sex- an X chromosome and a Y chromosome. Women also have 46 chromosomes but have two X chromosomes. Sperm contain a half set of DNA- 23 chromosomes including an X or a Y, to add up with the egg's 23 chromosomes and an X to make a baby. XX is a girl, XY is a boy.
