Every month

  1. Mar 16, 2005 #1
    This is a serious question. I'm not posting it to be vulgar or obsene. :confused: My sisters, our mother, and I are noticing that our monthly cycles are almost 100% in sync with each other. We thought this was pretty weird. Mainly because our cycles used to be at completely different times of the month. We're noticing this more and more because we all get emotional and suffer from PMS at the same time :devil: . Not to mention we kept having to go to the store for supplies.

    Why does this happen? Is their some medical/biological for why this changes our cycles so they happen at the same thing?

    I wish there was something we could do so we don't try to kill each other while we PMS together. Midol just ain't cuttin' it no more. Lol. :rofl:

    It's believed to be due to pheromonal cues. Here's a somewhat recent article about a possible chemical that could be involved as a pheromone.

    Positive relationship between menstrual synchrony and ability to smell 5alpha-androst-16-en-3alpha-ol.

    I think it's free access.

    This phenomenon is commonly observed in laboratories that group house their females. I believe some researchers use it to increase their hit rate when trying to generate timed-pregnant animals.

    It's far better documented among those non-human animals than in women.

    The men go off to war one week a month because it seems safer? :biggrin:

    I live with three girls, and they always manage to synchronise their periods, which would be fine except for them all suffering from monster PMT. Actually, it's not the girls who suffer from the monster PMT, it's me.

    It's horrific, it's like they're scheming behind our backs to turn the house into a raging den of hormonal aggravation for a few days every month. Moonbear, you say it's likely to be pheromonal. That's smells and stuff isn't it? Do you think that by using Febreeze there'd be any chance I could neutralise the pheromones, thus breaking the synchronisity, and spreading the rage out again?

    I don't think febreezing your house would do it. You could always do what my grandfather did...same problem you have....build a garage 1/2 mile away from your house and hang out there and only go back to the house for food and a place to sleep. (you can build a restroom in the garage).

    Sorry, febreeze won't work. It isn't scents they are leaving on the furniture, it's scents their own bodies are producing.

    misskitty might be right, this is probably what drives men to think the garage is a great place to hang out all day. :biggrin: Get yourself a calendar and start tracking cycles. When you know it's time for the PMS to start, if it's bad enough, start making a lot of extra trips to the library for studying, or running errands all over town, or hang out at a friend's place. :rofl:

    Not a bad idea.

    There was another question that deals with monthly cycles that I don't really feel needs to be in a separte thread. Can anti-depressant medications throw your cycle out of whack? Mess with the regularity so instead of having it the 2nd week of the month you'd have it the 4th week? How long does it take your body to readjust to the change? Does this happen when you come off the medication?

    I'm just asking. I'm not on meds if that's what you're thinking, :wink:.

    I don't have time for the long answer now, so the short answer will have to suffice. Yes, some antidepressants can interfere with menstrual cyclicity (and sexual desire as well).

    Ok. That works, you can expand on it later. Thanks.

    During my university years, a number of women confirmed this.

    I definitely responded to my wife's hormonal cycle. I was most interested when she was fertile.

    Hmmmm, so scent is involved in synchronization of menstrual cycles. And it appears this occurs across the animal kingdom. So in the course of animal evolution, the genes that allow for this, have probably been around for awhile.

    Is this synchronization useful, might there be an adaptational advantage? :rolleyes:

    Absolutly! It lets you know who to stay away from during a particular week of the month so you can keep all you body parts! :biggrin: As far as the the other thing you might be thinking...I have no clue and I'm not even gonna touch that one. :tongue2:

    I used to have a little application which sat on my taskbar and gave me little warnings when my girlfriend was likely to have a PMT attack. It had two modes: one just used the 'average' cycle to try and predict the woman's characteristics; the other allowed you to input exact characteristics and was much more accurate! It definitely saved my skin once or twice.

    I can't find the link now, but I think it was called PMS Alert.

    Are you serious? They actually have those things? I find that a bit hard to believe.

    If you don't have a good sense of humor, including even some that is far from PC (Politically Correct), stop reading now.
    Some wag recently explained why it is called Pre Menstrual Syndrome, PMS, and not MCD. (name Mad Cow Disease was already taken.)

    Yeah! It was quite amusing, but also quite useful!

    It was called PMS Alert, googling it finds plenty of people recommending it, but download.com has stopped serving it, and I can't find it anywhere else (read that as I can't be arsed looking).
