I'm not sure if this really fits in with this, but I bought both the male and female fragrances. They started acting like newlyweds, so I plopped one on the other and they had a kid. They were arguing beforehand and I honestly can't remember their ages. Might be worth a shot. I originally bought the fragrance because I thought there was a trophy related to it, then tried to have a baby and viola!! It might work with just one fragrance, or maybe it has nothing to do with it. Happy procreating!
