The Joys Of Science
|
The Joys Of Science Scientists are finally discovering something women and savvy men have known all along. That the clitoris becomes erect and non-erect tissue changes when a woman is aroused. Old news, you say? Well, not that old. Scientists at the University of Washington have been studying, lecturing and reporting on this since 2000. The last report of their continuing research was last year and they're not done yet. The first actual published MRI story was in 2002. This is from that published report: PURPOSE: To determine whether magnetic resonance (MR) imaging with MS-325, a recently developed blood pool contrast agent, can depict sexual arousal response in healthy women. I'm sure it comes as no surprise to women that a good number of men, (not ALL of you, so don't get snarky,) can't tell if a woman is aroused or not. So I'm actually glad there's now scientific proof. MATERIALS AND METHODS: Serial MR imaging of the external genitalia was performed in 12 healthy sexually functional women before and after administration of MS-325. MR images were obtained every 3 minutes during a 45-minute examination. During the examination, the subjects viewed neutral and erotic video material while they were in the magnet bore. The way I've read this was done was, 15 minutes of neutral material, 15 minutes of porn, 15 minutes of neutral. I'd love to know what the neutral material was. Steven Segal movies? Nova? Carl Sagan lecturing? MR image analysis at each interval consisted of vaginal wall, vaginal mucosa, and clitoris assessments; femoral vein signal intensity measurements; relative regional blood volume (rRBV) calculations; and clitoral volume measurements. Statistical analysis of the results was performed with a t test. Basically, they were looking to see if women actually become wet and if the clitoris swells. No, you geniuses, we've been peeing into our vaginas for years, to fool you all. RESULTS: On subjective questionnaires, all subjects in the test group reported being sexually aroused. MS-325-enhanced MR images showed strong contrast enhancement of the external genitalia. The rRBV in the glans clitoris of seven of 10 subjects and in the clitoral body of eight of these subjects increased significantly (P <.05) during erotic visual stimulation. All 10 subjects had a significant (P <.05) increase in clitoral size. There were no significant differences in any measures between the pre- and postmenopausal study groups. CONCLUSION: The sexual arousal response in healthy women can be monitored at serial MR imaging with MS-325. This examination holds promise for future studies of sexual arousal dysfunction in women. They claim they're doing these studies for research into sexual dysfunction in women. Which would be fine and dandy, but these studies are all just looking at sexually healthy women. I personally think they were a bunch of geeks who didn't believe their dates when they were told the clitoris swells and becomes erect and hard. Or, like so many, they were trying to find out where the clitoris really is. Or, they could just like looking at genitalia and figured out how to get a grant to spend their time doing that. I'm not joking about the healthy women. In July and August of 2003, two more studies were published. In July the report states: A total of 12 healthy premenopausal and 9 healthy postmenopausal women underwent MRI. The results this time showed the clitoris does become erect, mucus membranes release lubrication, there are changes in the labia minora and vulva. And yes, post-menopausal women don't have the same kind of vaginal and cervical response as pre-menopausal. Well, duh. But what were their conclusions? Differences in the female genitalia between premenopausal and postmenopausal women were discernible on MRI. These data are important for future studies using MRI for evaluating anatomical anomalies, postoperative changes and female sexual function. Basically, they are looking for the female orgasm. Because none of these studies have been done on any women in the groups they stay these studies will help. This is the entire report in 2004: We utilized contrast enhanced magnetic resonance imaging (MR  to delineate the anatomy of the female genital and pelvic organs during sexual arousal. Eleven healthy pre-menopausal women and eight healthy post-menopausal women underwent MRI of the pelvis while watching an erotic video. A 1.5 Tesla MR system was used to produce T1-weighted images following administration of MS-325, a gadolinium-based blood pool contrast agent. Selected structural dimensions and enhancement were measured prior to and during sexual arousal. In both pre- and post-menopausal subjects, vestibular bulb and labia minora width increased with arousal. Enhancement measurements increased in the bulb, labia minora and clitoris in both pre- and post-menopausal subjects, and in the vagina in pre-menopausal subjects. There were no marked changes in size or enhancement of the labia majora, urethra, cervix, or rectum during sexual arousal in pre- or post-menopausal subjects. Using MRI, we observed specific changes in the female genitalia and pelvic organs with sexual arousal, in both pre- and post-menopausal women. MRI can potentially provide detailed anatomical information in the assessment of female sexual function, particularly with regard to changes in blood flow.Well, there are going to be a LOT of disappointed men who are SURE the rectum opens up during sexual arousal. Or that the<b> urethra </font></b>isn't a second clitoris. (I'm not making that one up at all. You'd be amazed.) But once again, the reason for testing sexual functions in women has changed. I'm not going to bore you with all the studies. The findings at this point are: Women become aroused. The vagina secrets mucus. The clitoris becomes engorged and erect. There are changes in the labia minora and bulbs of the clitoris. The vagina widens. There are five stages of sexual arousal in women and we don't have an on/off switch. And we finally have a three dimensional view of the clitoris, the connecting tissue, the large nerves and how it reacts. So, because the clitoris is much like a penis, they're all stumped as to why ED drugs for men don't work for women. Even though they're not even looking at women with arousal dysfunction yet. Just women with sexually healthy appetites. And fetuses. And infants. Yes, baby girls, even those who are still in the womb have had their clitorises studied. This is where men should start having clitoris envy. The clitoral and perineal neurovascular bundles are large, paired terminations of the pudendal neurovascular bundles. The clitoral neurovascular bundles ascend along the ischiopubic rami to meet each other and pass along the superior surface of the clitoral body supplying the clitoris. The neural trunks pass largely intact into the glans. These nerves are at least 2 mm in diameter even in infancy. No wonder I discovered masturbation when I was five. But what is the final word so far? The work of Kobelt in the early 19th century provides a most comprehensive and accurate description of clitoral anatomy, and modern study provides objective images and few novel findings. The bulbs appear to be part of the clitoris. They are spongy in character and in continuity with the other parts of the clitoris. The distal<b> urethra </font></b>and vagina are intimately related structures, although they are not erectile in character. They form a tissue cluster with the clitoris. This cluster appears to be the locus of female sexual function and orgasm. This is something we've been telling our partners for years. Why didn't they just ask us? Oh yeah. They got to play with their big, um, machine to find out.  |

Too bad those Geeks didn't have wives or girlfriends. If so, they wouldn't feel the need to wast money that way. Maybe a good round of sex ed will help them. Bambi A Twat

Grant money going for something like this...................kinda explains why there's not enough to find a cure for cancer. Or aids. Or...............

I am highly amused. This wasn't a post I could read while multi-tasking and I'm very glad I came back to read it through properly. Your wit remains unrivaled. In other words. You slay me. The only thing I HAVE to do is eat, shit, and die. Everything else is a choice.

Very good posts. I just wanted to come by and thank you to your response to my posy on Childrens Meth. I take it that snopes is a web site that gives out misleading information? Well anyway...I deleted that posts, and again, I thank you for your input. And thanks for stoppin by my lil ole blog  It is a Journey…We all get there differently.

I was introduced to the clitoris very early; Ever since it has been a very treasured friend. My blog is a free-fire zone. Come armed with a sense of humor

At least the research is trying to develop tools for assisting women to have orgasms, which seems to be a worthy goal. The confirmation of an obvious fact by a scientific method is useful. Masters & Johnson did similar research and were lauded for showing contrary to Freud that all female orgasms were clitoral, and not vaginal.

You know... That wouldn't surprise me.

You know, I want a grant to do a full study on how many licks it takes to get to the center of a Tootsie Pop. But I don't even know where to look to get a grant. There is more to this than a one person study. Do different acid or alkaline levels in saliva effect it? The shape of the tongue? The gender? Does the flavor matter? There are even more things to take into consideration too.

You know, I bet we can start a conspiracy theory based on that. It would insure the conspiracy theorists don't get laid and don't breed.

And thanks for stoppin by my lil ole blog A few of my friends are so used to getting email back with the link to Snopes that identifies something as an urban legend, they ask me first, before they forward. A few others have actually started visiting the site themselves. It's been around for as long as I can remember.

Masters & Johnson did similar research and were lauded for showing contrary to Freud that all female orgasms were clitoral, and not vaginal. But there is a vast minority of women who can have vaginal orgasms without clitoral stimulation. Something like 20% of all women can do that.

Hmm, I never thought of using an MRI as part of foreplay. Thank you Miss Ann for helping me see the light. [blog talldarkavg1]

According to Masters & Johnson, the clit extends down into the vagina and intercourse also stimulates the clit in some lucky women. They claim all female orgasms involve the clit...

Freud was creative but his theories make much more sense interpreting fantasies and dreams than as a real human therapy. He also recognized that eventually biological science would supplant his musings by neurobiological investigations. He admitted that he did not understand women!

The MRI study has allowed 3-D imaging that showed how everything is connected. So it's a yes and a no to Masters and Johnson. It connects, but it isn't responsible for vaginal orgasms. Unless of course, a woman is having her clitoris stimulated during vaginal intercourse.

I must confess that I skipped reading the replies. Healthy women give a good base to explore from. Setting the boundaries of healthy may help them discover the problems outside the realm of their understanding. We really don't spend as much money on women's health issues as we do men's. Finally, I like this post because it was educational. While your handle is prominently displayed over the image of this post, I thought it looked like one of those Si-Fi things, like the eye with teeth. Except this one looks like a flesh tone scary movie face wearing a clitoral hood, inside of a really furry parka hood. I like your thoughts on the Aretha. She may have rhythm that's cool while driving a vulva, but you would need something hotter if you drive the Perineum Falcon. Sorry, it's Stupid Friday.

Actually, I've always believed finding a cure for major diseases isn't the goal of the foundations. They get so much private money, the people who work for them make so much money, a cure would cut off all those jobs and all that money coming in. Kinda applies to a LOT of things........at the moment wondering how much this applies to global warming. Getting a grant to study a problem kinda grantees embellishment.......to get more grants. What brought this thought up, was a report I read recently saying the Antarctic icefield was the largest recorded..........

The thing that bothers me most about this? They probably had extensive government grants.. ~jeff
