None, very carefully planned

Since it is the man who determines the sex of the child, I concentrated very hard.

The ancient Greeks believed that boy sperm came from one testicle and girl sperm from the other, so if they were trying for one sex in particular they would bind up one testicle with a tight leather thong.

I base my (irrefutable) findings on daughters on a random selection of the children of my friends who were silly enough not to concentrate hard enough, and my god-daughters.
