Do orgasms really make women fall in love?
Recent reports claim oxytocin makes ladies get clingy after sex, but an expert calls foul
This week I started having flashbacks to the hookup hysteria of a few years back. It started with a Daily Mail piece headlined, “Sex: Why it makes women fall in love — but just makes men want MORE!” Other outlets picked up on the story and the women’s blog the Frisky bleakly concluded, “After sex, men are feeling satiated, perhaps thinking of sleep or pizza, or the next time we’ll do them and we are stuck wondering whether or not we love him.”
The original report, if you can even call it that, claimed to be about a recent study out of Rutgers University, but much of the content — especially about how orgasms cause a flood of oxytocin, commonly referred to as the “cuddle drug,” that makes women indiscriminately fall in love — was attributed to a U.K. doctor who had nada to do with the actual research. This bait-and-switch threw me for a loop, but I eventually tracked down the researcher who inspired these grand, sweeping statements. Barry Komisaruk, a professor of psychology at Rutgers, says he found no such thing.
It’s tempting to shrug off misreporting by the infamous Daily Mail, but it’s far from the first publication to further the oxytocin love story. This popularly accepted wisdom has also been used to back up moral arguments against premarital sex, sometimes by influential officials — like Eric Keroack, a Department of Health and Human Services appointee under President George W. Bush, who believed casual sex depleted women’s stores of oxytocin thereby ruining their ability to romantically bond. I talked to Komisaruk about what we really know about women, orgasms and love.
What did you actually find with regard to orgasms and oxytocin in women?
During orgasm in women, I see activation of the dopamine target region, which is the nucleus accumbens, and activation of the oxytocin-producing region of the hypothalamus. What that means is that during orgasm, we’re not measuring dopamine or oxytocin directly, but we’re measuring the activity of brain regions that respond to dopamine and the brain regions that produce and release oxytocin.
How does that compare to orgasm in men?
You can’t exactly compare it, because it’s apples and oranges. We’re just beginning to study sexual response and orgasm in men. The only other people who recently have studied orgasm in men is a group in Holland and they use a PET scan, a very different method from the functional MRI we used. They claim that there are some differences in orgasm between men and women, but overall I would say, based on their research, that the similarities are much greater than the differences in orgasm between men and women.
That’s not at all the message communicated in the media. Usually, you see reporting on how orgasms cause women to be flooded with far more oxytocin –
It’s true that women have a peak of oxytocin at the time of orgasm, whereas men have a more gradual increase, but that’s based on blood level measurements. I have to say something very important that people don’t recognize, particularly in the mass media: Oxytocin is both a hormone and a neurotransmitter. That means it’s released into the blood as a hormone from the pituitary gland at the same time it’s released into the brain as a neurotransmitter. The oxytocin released in the brain could be having different properties and different effects than the oxytocin that’s released into the bloodstream.
When it’s released into the bloodstream it mainly produces contractions of the uterus (which may serve to pull semen into the uterus and helps push out the fetus during childbirth) and the mammary glands (which squeezes out milk into the baby’s mouth). Very little oxytocin gets into the brain from the blood, and any effect of oxytocin on behavior is due to its release in the brain as a neurotransmitter. We don’t really know what effect it has in humans.
It’s so often referred to as “the cuddle drug,” the “love hormone” –
The evidence of stimulating pair bonding and cuddling, that’s based on injection of oxytocin directly into the brain in rodents. There’s no evidence like that in humans. I keep checking the literature on that because I’m very interested in it, but there’s actually no evidence of oxytocin as a love hormone in humans. You have to be very careful about any romantic role attributed to humans based on research on non-humans.
Just to be utterly clear: Is there any evidence to back up the idea that oxytocin leads women to experience greater post-coital feelings of love than men?
There’s really no evidence of it. Somehow it caught the imagination of the public, but it’s based on rodents. It’s possible, I’m not saying it’s impossible, but there’s no experimental evidence to support it — in humans.
Not only are these conclusions a huge leap, but I’ve seen them used to further political arguments — for example, against casual sex, the idea being that it’s more harmful to women because they become more emotionally attached.
Yeah, yeah, I know.
So any time that we see oxytocin broadly linked to love, that is an unmerited simplification?
What one can say is that during orgasm oxytocin is liberated into the blood — that’s been shown. There’s also some evidence that oxytocin is released into the blood during hugging … but, again, that’s oxytocin released into the blood. That could be a response to the loving behavior rather than a cause. It’s a correlative of it, it could just be a side effect, because oxytocin in the blood doesn’t have any significant behavioral effect.
Now, it’s possible, and I would even say likely, that orgasm and maybe hugging cause the release of oxytocin in various places in the brain. But there’s no evidence that such oxytocin that’s released into the brain has any effect on behavior in humans.
So even having evidence of oxytocin released in the brain, we don’t know that it would result in feelings of love.
That’s right. It’s extremely difficult to show that — you can inject the oxytocin into the brain in animals but you can’t do that in humans. It’s very likely that something like that happens but there’s no evidence of it and you can’t jump to conclusions based on something that seems logical, because we’re always fooled and surprised by mother nature. There’s an expression, “It may be logical, but it’s not biological” — or at least it hasn’t been shown biologically in this case.
Right, it seems to make intuitive sense but there isn’t evidence to back it up.
Exactly.

Taxing strip clubs for rape
Politicians are holding adult entertainment venues responsible for funding sexual assault services
(Credit: iStockphoto/wragg) It used to be that strip clubs were merely blamed for society’s ills. Now they’re actually being charged for it.
In recent years, measures have been introduced in Georgia, Pennsylvania, Texas, Illinois and, most recently, California to apply special taxes to strip clubs — specifically to fund sexual assault services. Now, even if you aren’t inclined to view erotic entertainment as the source of all evil, this might seem an appropriate aim — who wants to argue against additional support for rape survivors? It would seem even more so when you consider politicians’ and activists’ repeated claims of solid scientific evidence showing a link between strip clubs — specifically those that sell alcohol — and sexual violence.

Massage therapists rubbed wrong by sex talk
A Jennifer Love Hewitt show and the Travolta allegations have masseuses tired of being confused for sex workers
(Credit: iStockphoto/sybanto) Joe, a licensed massage therapist, knows what it’s like having a famous client who expects something extra. He had an Academy Award-winning actor begin gyrating on his massage table before raising his hips in the air to show off his erection. “He was hoping that I would play with him in some shape or form,” he says.
Needless to say, Joe isn’t surprised by allegations by two masseurs that John Travolta got handsy during massages. (Travolta’s attorney has denied all the allegations, and called them “ridiculous.”) “It happens all the time,” he says, and not just with celebrity clients. He frequently encounters men who try to fondle him, usually while he’s working on their glutes or lower back and their hand happens to be level with his crotch. “They think they’re so original, but they’re all so much the same,” Joe says, his voice rising. “They all use the same tactics, the same body movements, the same gyrations and grinding my table, the [heavy] breathing.”

A night at the vibrator museum
Early vibrators were hand-cranked, two-person jobs -- and prescribed by doctors. How far we've come since then
(Credit: Antique Vibrator Museum) I can now say that I’ve used a turn-of-the-century vibrator — on my hand, but still.
The silver, hand-cranked contraption is usually kept behind glass at Good Vibrations’ Antique Vibrator Museum in San Francisco — but staff sexologist Carol Queen made a rare exception. “This is very special,” she whispered, unlocking the case and carefully pulling out Dr. Johansen’s Auto Vibrator, a relic from 1904. The “auto” part is not so much: It was a two-person job, with her having to crank the device’s handle to get it thrumming. Pressing my finger tips to its inch-wide circular platform of pleasure, I was pleasantly surprised by its power.

Maggie Gyllenhaal on sexual liberation
The beloved indie star tells Salon about her "vibrator movie" and why she loves playing transgressive women
Maggie Gyllenhaal (Credit: Reuters/Mark Blinch) When I met Maggie Gyllenhaal about six weeks ago, she was enormously and gloriously pregnant, stretching out on a sofa with her shoes off and feet up in a Manhattan office building. (Since that time, Gyllenhaal and husband Peter Sarsgaard have welcomed their second daughter, Gloria Ray, to the world.) We were there to talk about “Hysteria,” the charming, lightweight feminist farce from director Tanya Wexler that explores a key event in the history of female sexuality: the invention of the vibrator by Mortimer Granville, a Victorian doctor who was seeking to cure the mysterious “female malady” that lends the movie its title.

Susie Bright and her daughter, Aretha, make parental talks about sex look easy -- and fun
Most parents loathe talking to their kids about the birds and the bees, let alone pubic hair grooming, faked orgasms and “water sports” — but most parents are not legendary “sexpert” Susie Bright.
Better than talking about these things, she penned an advice column in 2009 with her daughter, Aretha, then 19, for the ladyblog Jezebel. Their answers to questions about everything from porn to Paxil were unflinching but playful, and at times controversial. Now the pair have collected those columns into a new e-book, “Mother/Daughter Sex Advice.” Together, they read as an irreverent version of “Our Bodies, Ourselves” for the Internet age. The mother-daughter team also reflect on what the experience of writing the column was like, and it turns out it wasn’t as weird as many would think: For the most part, it was just a continuation of conversations they had been having throughout Aretha’s life.
