"Yes, I have four children. Four children with whom I spend a good part of every day: bathing them, combing their hair, sitting with them while they do their homework, holding them while they weep their tragic tears. But I'm not in love with any of them. I am in love with my husband."

Girl Power or: Partnership status and the human sex ratio at birth: a paper by Karen Norberg Could the sex of a child be influenced by the status of the parents' relationship at the time of conception? In a sample of 86,436 births in the United States, we find a small excess of sons among births to parents who were married or living with an opposite sex partner before the child's conception, compared to births to parents who were not. This is the first evidence that household arrangements can affect the human sex ratio at birth, and could explain the fall in the proportion of male births in some developed countries over the past thirty years.
