And does anyone know why a group of wimmin living in the same community for awhile will start to be on the same menstration cycle?

I've thought about that and I don't know if there's any real explaination to why that is. I totally sync my cycle after my sister whenever she's around though.

She lives abroad and some time ago she was coming back home. I was very later then, like 2-3 weeks, (unusual for me, might've been the tension) and the day she walked in, I started my period (and so did she). After that my cycle was the same as hers.

After she left, it slowly changed back to my usual cycle. I thought it was strange but cool (and maybe a coincidence?), since normally it seems that rather women who live together for a while (and are affectionate towards eachother) adapt the same cycle.

Ok, this was a bit of a confusing post.. But the subject is interesting.

it's something about the pheromones (sp?) i noticed that a colleague and I started ours about the same time, before mine went haywired.

It is a hormone/pheremone thing. I've found that even though I am on the pill I have been adapting to the girls in my section here in residence so much that I start a week earlier than I did in the summer!

It doesn't always happen. Despite 6 years of living in the same house together while I was old enough to be menstruating, my mom and I *never* synced. Her cycle was really short (around 23 days), and mine was really long (around 34 days). Maybe they were just too off to begin with?

Yup, it's pheromones. One interesting study also suggested that some women are "menstrual pacesetters," who make other women conform to their cycles, rather than having the entire group's cycle shift slightly. But it's not just living with women that can alter your periods: regular association with men is supposed to make your cycles shorter and more regular.

No one knows exactly "why" women do this. Some people have hypothesized that it's a holdover from prehistoric times, and that women in their peak fertile times give off some sort of pheromone that makes males go mad with desire. If all the women are fertile simultaneously, even if the guy screws up and has sex with the non-pheromone-emitting woman, the theory states, the synchronized cycles will still help ensure conception. Another theory holds that the phenomenon enchances complementary relationships among women: like "sympathetic pregnancy."

Wow..0_0..Muy interesante (very interesting). Thank you.

Nature?

I don't have a scientific answer, but what I can say is that dairy farmers have found this to be true in nature. All the goats will cycle together, all the cows will cycle together. This means that birth times and milk production will be cyclical and they have figured it out enough to make it produce the money, also. So if we watch nature we can see that the animals tend to congregate a little closer during birth times and early infanthood so that the babies are better protected. Think that may be the same with us?

I'm not sure it happens as often as folks say it does. I've never synched with a roommate, and I've had female roomates for a total of 20 years of my menstruating life.

But it can happen. I haven't heard an explanation as to why, yet.

Just about every female I've been with for a long period of time have sinc-ed with me or I with them.

I heard a study (yeah, scientific), that often it happens so that a 'mating' season can occur. As humans we have the cycles much more often then many other species. However, it kind of makes sense. Many births occur because of the mating season (and the higher amount of pheromones released at a very similar time). It's a way for species to survive.

I just woke up. Hopefully this all makes sense.

it's an interesting phenomenon, to say the least. last year, my period went haywire when i was living in a dorm, because it would want to start at the same time as anyone else's. i was having it about every other week. it was awful.

good question

[raticus.livejournal.com]

I don't think you have to be affectionate/freinds with someone to adapt the same cycle. when I was first starting my cycle I adapted my mums freinds cycle.

I've heard sometimes it can be caused by lunar cycles and gravitational pulls... but I haven't really researched into that.

Not everyone in my dorm in college would sync, but enough of us would, or get close enough together, that the itty bitty garbage cans in the bathrooms would be seriously stuffed. When I first started living with two roommates, our cycles got seriously screwed. For a couple cycles I was doing 2 weeks between periods. Ugh!

God damn it...I just finished reading your info page. I wish I was as ambitious as you were. It makes me feel very good to hear about a gurl in the sciences and math. Keep up the good work!

I believe it's due to pheromones. . .I tired looking it up in my physiology textbook, but they don't say much of anything about it. There's obviously something to it though, because within something like two months, my roommate and I were on exactly the same schedule. As in, we usually start on the same day. It's kind of neat, in a weird way. :-)
