Everybody knows about PMS, but do women change their behavior during ovulation?  Current research says they do, sexually, and these changes may have evolutionary significance in spreading our genes.Two new studies in the November issue of the journal Evolution and Human Behavior find that women get a little wilder during their most fertile days of the month.  One study found that ovulating women are more open to the idea of hooking up with a stranger or acquaintance, while the other study found that women with less masculine-looking partners are more likely to lust after men with “masculine” traits–like strong, square jaws–than women with partners already possessing those traits.In the past, most research on the menstrual cycle focused on premenstrual syndrome (PMS), but these new studies are two of more than twenty focusing on behavioral changes brought about by ovulation.  Researchers in evolutionary biology have taken it for granted that ovulation is of slight significance since humans have deviated from the typical estrus cycle (heat) of mammals, and can be up for sex anytime of the month.This, however, is just a theory, and a wrong one at that.  For instance, men can tell when a woman is ovulating, although they do so imperfectly.  Some experts believe it’s through smell–of pheromones, excreted chemicals that triggers a social response in members of the same species–but this is just a hypothesis.  Several studies, however, have found that women report that their men become more attentive and jealous around fertile days. One study, in fact, found that when women were fertile, their male partners saw other men as a greater threat.Further, women do have a sort-of “heat” phase, yet instead of simply being more receptive to sex, they want it for different reasons.  Consider this phase a lust-cycle, where women want sex for sex’s sake and not for intimacy, which might be more the reason outside of the cycle.

The second study of the pair looked at womens’ phenotypic preference for masculine traits during fertile periods.  Several previous studies had found that, when ovulating, women tended to go for more masculine-looking men.  Masculine traits fertile women prefer are strong-jawed faces, muscular bodies, dominant behaviors, deep voices and tallness.

(Example of test picture to the left–women, which face do you prefer?)

In the latest study, researchers found that if a woman is partnered with a man without a masculine face, her eye is more likely to wander during her fertile days. Now this doesn’t mean she’ll necessarily act on her wandering eye, but she’ll likely look nonetheless.  And other studies have shown that the hormonal fluctuations surrounding ovulation do change women’s attitudes and behavior.  For instance, fertile women seem to be more open than non-fertile women to the idea of taking “sexual pleasures where [they] find them.”  According to the authors of the study, women in ovulation are more likely to express interest in sleeping with an attractive stranger or someone they don’t care about.  Just sex.

Women in ovulation also tried harder to look nice for pictures, according to a 2006 study, showing that the hormonal changes may also affect female decision making.  An online shopping experiment reveals fertile women are also more likely to choose sexy clothes and accessories than women who weren’t fertile, according to the study published online in the Journal of Consumer Research in August.  Finally, in a widely publicized study published in Evolution and Human Behavior in 2007, researchers found that ovulating strippers made an average of $30 more an hour than menstruating strippers and $15 more an hour than non-ovulating, non-menstruating strippers.

So to conclude, during fertile periods, women tend to be a bit friskier, make decisions about their attractiveness, look harder at masculine features, and be more likely to engage in casual sex.  Why?  To ensure the likelihood of fertilization and to increase the probability of finding successful genes, biologically speaking that is.  I don’t know about you, but it sounds to me like the human female is as much a product of her biology as a man is.  Cool, huh?

    This is so true. Women can be just as horny as men in their non fertile days too.

    I would have sex with anything that moves and has a dick during ovulation. I never noticed it before, but now I keep track and when I wake up in mid-orgasm, I know that I’m ovulating.
    I’m 19 and only had sex with one guy who used to be my ex-boyfriend, so no, I’m not a whore, and I will never sleep around, I’m actually trying to stay chaste until I get married now, but it gets REALLY frustrating and I have to literally get up and do myself in the bathroom during that time.

    • The magnificence of biology! Can’t escape it :)

      Yeah I know what you mean! I never really noticed it before either but I’ve seen a difference in who I find attractive when I’m ovulating. I go from preferring a more fem. face during my non fertile days to preferring really masculine guys,for the most part. I think about doing every guy I see. I read/watch lots of porn.I’ve nvr had sex before in my LIFE and I’m hoping to keep it that way until marriage. But,it’s times like this where I feel like I’m gonna lose it. “It” being my mind.

      I know the feeling…it’s…amazing and frustrating at the same time, especially when there’s no one to have sex with.

    I know when I’m ovulating because I actually “think” differently. My focus is a bit off at work. This is in addition to my non intentional frisky/flirty behavior…and desires. For me, this really sucks considering I am celibate and would like to stay that way until marriage. I wish there was some sort of biological button “sleep mode” –so to speak. I do want to have a sex drive once I’m married…

    Yeah, in a period like this you walk along the street and enjoy strangers’ attention–a woman like a magnet! So true! Men feel it, eat you with their eyes- the best days to meet your puzzle ( for a long lasting relashionships- it happens or “just” as you mentioned)
    Even the face is more radiant and I always put less make-up: eyes are brighter and lips are fuller- what for to hide this beauty?
    Knowing all these “bio secrets” you understand why you can be addicted to a woman (right time -period-, right place)

    From when I was 13 to about 21, I never noticed this happening, but within the last year, it has been ridiculous. The need never seems to be fulfilled.

  6. India says:

  7. anon. says:

    Add “In the west” where sex ratio is low.

  8. Shabana says:

    I am 28 yr old.
    I have one child who is almost 5yr old.

    I am a single working mom and lady.

    I dated a few men here and there.
    Nothing. Serious.

    My x bf how ever I can’t get enough of.
    We aren’t together anymore but when ever I want sex I call him always. He comes over and spends all night and half the following day with me.
    I am in heat once a month but when it happens I am horny for an entire week straight. I am seeing someone right now but I promised myself that I wouldn’t sleep with someone so quickly again. Even though I am talking and dating somebody we are not boyfriend and gf yet. I don’t have that trust in this new person yet.
    where as the person aka my x bf we have been friends since we were kids. We have trust in one another even though we broke up. We still love to sleep together. He knows when I am in heat because 1) as soon as he walks in my door we are hugging and my legs are wrapped around his waist. 2) he carries me to the bedroom and kisses me non stop. 3) when we have sexton he feels me having the biggest orgasms when I am in heat. 4) sexton with him is amazing.

    I am in so much heat right now. I am getting butterflies and upset because I want and need sex. I called my x to come over so we have it planned for Friday night.
    I also feel guilty because the man I am dating also has a big dick…..and he dry humped me with his boxers on and it made me so thorny. I almost caved in. I told this new man that if he wants sex with me I need to know that our relationship is a stable strong one and that I cannot just gave sexton in the first week of dating.
    So can anyone tell me what to do because when I go in this much heat masturbsting with my toy doesn’t do it for me.
    I need the real deal

    Today I woke up and put on makeup, and painted my nails for the first time in a few weeks. I just felt sexy! I also was a little more friendly to people in general, not just men. I am now getting those familiar stirrings signaling ovulation, and sure enough I checked the calender and my period was fourteen days ago. Go figure!

  10. April says:

    They need to bottle this. I would buy it because I love this part of the month

  11. Lyraithia says:

    I completely understand how that works, I’m in ovulation right now and for some reason am only attracted to one guy at the moment (my boyfriend), he’s not really muscular, but his voice hits that nice deep pitch, he’s tall, broad shoulders, and facial hair….I can help but want to jump him, but I’m also trying to keep my V-card until after I’m married….but God is it hard! Especially when he’s been sweating from doing things outside….I’ve actually found myself nuzzling my nose into his armpit and taking deep breathes, for some reason I just can’t help it. I even had my wisdom teeth out yesterday and he stayed with me the whole time, but afterwards, I still found myself wanting to jump him…..I think I might have a Really bad case…..cuz when I’m not ovulating I’m not like this at all, when I’m not ovulating he tries starting stuff, but when I am, I start stuff.
