Position determines gender of child?

Question

I've heard that different positions can make the possibilities to increase a boy or girl for a child. Is it true?

Answer

Sex positions, no.

However, it is said that if you have sex right when you ovulate,the faster swimming male sperm gets to the egg.

If you have sex before you ovulate, the faster male sperm get there, but there is no egg and they quickly die off. The slower swimming, yet stronger female sperm have more of a chance.

Answer

There is no medical proof to back this up. The most you can do is find old wives tales on the subject, but, you'll find one who says "girl on top gets a girl" and the next says "man on top gets you twin girls."

Answer

This is ridiculous. No.
