It's been shown that the length a woman's period actually decreases when she lives with a male. They also tend to become more regular.
As for the menstrual cycle synchronizing with other female's when they live in close quarters; it may be due to a hold-over from when males would have multiple mates. If all of the females are fertile at the same time it increases the chances of conception. If the females were not all fertile at the same time it would be up to chance since ancient humans had no "real" way to determine fertility.
Males have hormonal cycles too ... where does the theory fit in with that?
