1、ted经典演讲稿英文TED经典演讲稿:Mary Roach: 10 things you didnt know about orgasmAlright. Im going to show you a couple of images from a very diverting paper in The Journal of Ultrasound in Medicine.Im going to go way out on a limb and say that it is the most diverting paper ever published in The Journal of Ultr

2、asound in Medicine. The title is “Observations of In-Utero Masturbation.” (Laughter) Okay. Now on the left you can see the hand thats the big arrow and the penis on the right. The hand hovering. And over here we have, in the words of radiologist Israel Meisner, “The hand grasping the penis in a fash

3、ion resembling masturbation movements.” Bear in mind this was an ultrasound, so it would have been moving images.Orgasm is a reflex of the autonomic nervous system. Now this is the part of the nervous system that deals with the things that we dont consciously control, like digestion, heart rate and

4、sexual arousal. And the orgasm reflex can be triggered by a surprisingly broad range of input. Genital stimulation. Duh. But also Kinsey interviewed a woman who could be brought to orgasm by having someone stroke her eyebrow. People with spinal cord injuries, like paraplegias, quadriplegias, will of

5、ten develop a very, very sensitive area right above the level of their injury, wherever that is. There is such a thing as a knee orgasm in the literature.I think the most curious one that I came across was a case report of a woman who had an orgasm every time she brushed her teeth. (Laughter) This w

6、as something in the complex sensory-motor action of brushing her teeth was triggering orgasm. And she went to a neurologist who was fascinated. He checked to see if it was something in the toothpaste, but no it happened with any brand. They stimulated her gums with a toothpick, to see if that was do

7、ing it. No. It was the whole, you know, motion. And the amazing thing to me is that now you would think this woman would like have excellent oral hygiene. (Laughter) Sadly she this is what it said in the journal paper “She believed that she was possessed by demons and switched to mouthwash for her o

8、ral care.” Its so sad.(Laughter)I interviewed, when I was working on the book, I interviewed a woman who can think herself to orgasm. She was part of a study at Rutgers University. You gotta love that. Rutgers. So I interviewed her in Oakland, in a sushi restaurant. And I said, “So, could you do it

9、right here?” And she said, “Yeah, but you know Id rather finish my meal if you dont mind.” (Laughter) But afterwards she was kind enough to demonstrate on a bench outside. It was remarkable. It took about one minute. And I said to her, “Are you just doing this all the time?” (Laughter) She said, “No

10、. Honestly when I get home Im usually too tired.” (Laughter) She said that the last time she had done it was on the Disneyland tram.(Laughter)The headquarters for orgasm, along the spinal nerve, is something called the sacral nerve root, which is back here. And if you trigger, if you stimulate with

11、an electrode, the precise spot, you will trigger an orgasm. And it is a fact that you can trigger spinal reflexes in dead people a certain kind of dead person, a beating-heart cadaver. Now this is somebody who is brain-dead, legally dead, definitely checked out, but is being kept alive on a respirat

12、or, so that their organs will be oxygenated for transplantation. Now in one of these brain-dead people, if you trigger the right spot, you will see something every now and then. There is a reflex called the Lazarus reflex. And this is Ill demonstrate as best I can, not being dead. Its like this. You

13、 trigger the spot. The dead guy, or gal, goes like that. Very unsettling for people working in pathology labs.(Laughter)Now if you can trigger the Lazarus reflex in a dead person, why not the orgasm reflex? I asked this question to a brain death expert, Stephanie Mann, who was foolish enough to retu

14、rn my emails. (Laughter) I said, “So, could you conceivably trigger an orgasm in a dead person?” She said, “Yes, if the sacral nerve is being oxygenated, you conceivably could.” Obviously it wouldnt be as much fun for the person. But it would be an orgasm (Laughter) nonetheless. I actually suggested

15、 to there is a researcher at the University of Alabama who does orgasm research. I said to her, “You should do an experiment. You know? You can get cadavers if you work at a university.” I said, “You should actually do this.” She said, “You get the human subjects review board approval for this one.”

16、 (Laughter)According to 1930s marriage manual author, Theodoor van de Velde, a slight seminal odor can be detected on the breath of a woman within about an hour after sexual intercourse.Theodoor van de Velde was something of a semen connoisseur.(Laughter) This is a guy writing a book, “Ideal Marriag

17、e,” you know. Very heavy hetero guy. But he wrote in this book, “Ideal Marriage” he said that he could differentiate between the semen of a young man, which he said had a fresh, exhilarating smell, and the semen of mature men, whose semen smelled quote, “Remarkably like that of the flowers of the Sp

18、anish chestnut. Sometimes quite freshly floral, and then again sometimes extremely pungent.” (Laughter)Okay. In 1999, in the state of Israel, a man began hiccupping. And this was one of those cases that went on and on. He tried everything his friends suggested. Nothing seemed to help. Days went by.

19、At a certain point, the man, still hiccupping, had sex with his wife. And lo and behold, the hiccups went away. He told his doctor, who published a case report in a Canadian medical journal under the title, “Sexual Intercourse as a Potential Treatment for Intractable Hiccups.” I love this article be

20、cause at a certain point they suggested that unattached hiccuppers could try masturbation. (Laughter) I love that because there is like a whole demographic: unattached hiccuppers. (Laughter) Married, single, unattached hiccupper.In the 1900s, early 1900s gynecologists, a lot of gynecologists believe

21、d that when a woman has an orgasm the contractions serve to suck the semen up through the cervix and sort of deliver it really quickly to the egg, thereby upping the odds of conception. It was called the “upsuck” theory.(Laughter)If you go all the way back to Hippocrates, physicians believed that or

22、gasm in women was not just helpful for conception, but necessary. Doctors back then were routinely telling men the importance of pleasuring their wives. Marriage-manual author and semen-sniffer Theodoor van de Velde (Laughter) has a line in his book. I loved this guy. I got a lot of mileage out of T

23、heodoor van de Velde. He had this line in his book that supposedly comes from the Habsburg Monarchy, where there was an empress Maria Theresa, who was having trouble conceiving. And apparently the royal court physician said to her, “I am of the opinion that the vuLVa of your most sacred majesty be t

24、itillated for some time prior to intercourse.” (Laughter) Its apparently, I dont know, on the record somewhere.Masters and Johnson: now were moving forward to the 1950s. Masters and Johnson were upsuck skeptics, which is also really fun to say. They didnt buy it. And they decided, being Masters and

25、Johnson, that they would get to the bottom of it. They brought women into the lab I think it was five women and outfitted them with cervical caps containing artificial semen. And in the artificial semen was a radio-opaque substance, such that it would show up on an X-ray. This is the 1950s. Anyway t

26、hese women sat in front of an X-ray device. And they masturbated. And Masters and Johnson looked to see if the semen was being sucked up. Did not find any evidence of upsuck. You may be wondering, “How do you make artificial semen?” (Laughter) I have an answer for you. I have two answers. You can us

27、e flour and water, or cornstarch and water. I actually found three separate recipes in the literature. (Laughter) My favorite being the one that says you know, they have the ingredients listed, and then in a recipe it will say, for example, “Yield: two dozen cupcakes.” This one said, “Yield: one eja

28、culate.” This one involves men.(Laughter)Theres another way that orgasm might boost fertility. Sperm that sit around in the body for a week or more start to develop abnormalities that make them less effective at head-banging their way into the egg. British sexologist Roy Levin has speculated that th

29、is is perhaps why men evolved to be such enthusiastic and frequent masturbators. He said, “If I keep tossing myself off I get fresh sperm being made.” Which I thought was an interesting idea, theory. So now you have an evolutionary excuse.(Laughter)Okay. (Laughter) Alrighty. There is considerable ev

30、idence for upsuck in the animal kingdom pigs, for instance. In Denmark, the Danish National Committee for Pig Production found out that if you sexually stimulate a sow while you artificially inseminate her, you will see a six-percent increase in the farrowing rate, which is the number of piglets pro

31、duced. So they came up with this plan, this five-point stimulation plan for the sows. And they had the farmers there is posters they put in the barn, and they have a DVD. And I got a copy of this DVD. (Laughter) This is my unveiling, because I am going to show you a clip.(Laughter)So uh, okay. Now h

32、ere we go in to the la la la, off to work. It all looks very innocent. Hes going to be doing things with his hands that the boar would use his snout, lacking hands. Okay. (Laughter) This is it. The boar has a very odd courtship repertoire. (Laughter) This is to mimic the weight of the boar. (Laughter) You should know, the clitoris of the pig, inside the vagina. So this may be sort of titillating for her. Here we go. (Laughter) And the happy result. (Applause) I love this video. There is a point in this video, towards the beginning where they zoom in for a close up of his hand with his weddin
