Strange link between housework and sex

How much housework he does may determine how many children she wants. That's right. Cooking, grocery shopping, vacuuming, dusting, laundry, and the dirty dishes can be a fertility booster or a contraceptive. Researchers from Brown University determined that 81 percent of couples in which the husband does at least half the housework will have a second child. But that number drops to 74 percent if the woman does most of the cleaning and cooking chores and has a job outside the home, reports BBC News Online.
