Actually the female has 100% of the control, as such. While obviously not under conscious control, the male delivers both male and female sperm, out of his control by any measure. It is the egg and it's enviroment chooses which makes it through. Like I hand you twenty red chips and twenty blue chips, and you choose the one you want, out of my control.

So while it is the individual sperm's DNA that makes the child a boy or a girl, it is the egg that chooses the individual sperm out of the crowd.
