What a Workout! Women Report that Exercise Triggers Orgasm

2012-03-22

Up to 15% of women apparently experience orgasm as a fringe benefit of physical exertion. Crunches, anyone?

Here’s one way to make workouts more palatable: combine exercise with orgasm.

It sounds like a pornographic fitness flick: women, sweaty from physical exertion, climaxing at the gym. But researchers at Indiana University say it really happens — independent of sex or fantasies. They’ve even got a name for it: “coregasm,” named thusly because abdominal exercises tend to spark the sensation.

In a survey distributed via the Internet, researchers asked women if they’d ever experienced exercise-induced orgasms (EIO) — 124 responded yes — or exercise-induced sexual pleasure (EISP); 246 had. Women were questioned about the types of exercises in which they were engaged at the time of orgasm, if the phenomenon happened repeatedly and whether they could control it, among other things.

Since there’s next to no scientific literature about orgasm while exercising, researchers prompted survey respondents to provide as much detail as possible. They learned quite a bit, according to lead author Debby Herbenick, co-director of the Center for Sexual Health Promotion at Indiana University.

Some women said they couldn’t help but make sounds during orgasm, which added to their feelings of self-consciousness. One woman wrote about biking strenuously uphill when she felt an orgasm coming on; embarrassed, she tried to hide it from her biking partner. According to the study:

“I had to really grind into the pedals. This must have caused me to rub on the seat in just the right away. I thought I was starting to cramp, but soon realized it felt great. [I] thought I should stop, but chose not to!”

Another woman described literally falling off a piece of gym equipment; one more recalled an errant medicine ball flying across the gym after she lost control. “Some talked about this happening as children during the Presidential fitness challenge, during pull-ups or chin-ups,” says Herbenick.

The research was published online Monday in a special issue of Sexual and Relationship Therapy. What’s so special about this issue? It’s all about orgasm: there are papers about tantra and orgasm, about non-genital kinds of orgasms deriving from mental fantasy, as well as criticisms about a perceived superiority complex surrounding vaginal orgasm. Says Herbenick: “It’s a very interesting issue.”

Herbenick’s contribution finds that exercise-induced orgasm is not of the wham-bam variety. In other words, don’t expect good vibrations from your first sit-up. “It’s often on number 15 or number 30,” says Herbenick.

Nor is what induces orgasm during exercise clear from this study. Most respondents said they weren’t daydreaming about sex at all. The catalyst seems to be the exertion itself, with abdominal exercises appearing to trigger the reaction in 51% of respondents. (The top orgasm generator in this category was the “captain’s chair,” a contraption in which the user supports her arms and back against a frame while the legs dangle, and she repeatedly raises her legs into a sitting position.) The next most likely culprits? Weight lifting, yoga, bicycling, running and walking or hiking.

Some women can induce orgasm by engaging in exercises that have previously yielded the big O; 40% of respondents reported they’d experienced orgasm or sexual pleasure while exercising more than 10 times. Others actively try to avoid climaxing in public; after all, it can be pretty mortifying. Yet even if it’s never happened to you, devoting some brain cells to its mystery and allure can serve as an excellent distraction during a workout. “Once you know about it,” observes Herbenick, “it is sometimes interesting to think about and wonder if others are experiencing it too.”

We know who’s not experiencing it: men. Sorry, guys, but this one’s (mostly) for the ladies. While Herbenick has heard of men orgasming during exercise, she says it’s far rarer. Even among the fairer sex, it’s fairly uncommon. Herbenick estimates that up to 15% of women have the uncanny and perhaps enviable ability to orgasm while exercising, a form of multitasking I’d never heard of before her research landed in my inbox. When I requested an interview with the author, an email response arrived with impeccable timing — just as I was winding up my morning boot-camp session. Alas, no fireworks.

Vaccines for Adults: What You Should Know

2012-03-21

In 2006 when the FDA approved the first human papillomavirus (HPV) vaccine, it was big news. The new HPV vaccination made headlines at the time, which wasn’t surprising considering that it was the very first vaccine approved to prevent cancer — cervical cancer, to be exact.

Even though the HPV vaccine have now been around for a few years, not everyone knows exactly what it is, or what it does. You might be wondering: How does it work? Is it safe? Should you or your child get it?

So you can be more confident when you talk to your doctor about the HPV vaccine, here are answers to these and other common questions about the vaccine.
What Is HPV?

HPV stands for human papillomavirus. It’s a virus that can be transmitted through sexual contact. During intercourse or oral sex, HPV can make its way into the genitals, mouth, or throat and cause infection.

Sexually transmitted HPV comes in more than 40 different varieties. The type of the virus you get determines what effects it has on your body. Certain types of HPV cause genital warts. Other HPV types can make cells turn cancerous. You’ve probably heard that HPV causes cervical cancer, but it also causes less common cancers of the vulva, vagina, penis, anus, head, and neck.

What’s tricky about HPV is that it doesn’t have symptoms. There’s no sore throat or fever to let you know you’ve been infected. Most people clear the infection on their own. In fact, you might have absolutely no idea you’ve been infected until you develop genital warts or have an abnormal Pap test.

Though HPV might not be as well known among sexually transmitted infections (STIs) as herpes or syphilis, it is actually the most common STI. If you’re sexually active, you’ve got about a 50/50 chance of being infected with HPV at some point in your life. That’s why immunization is so important.
There are two HPV vaccines; what’s the difference?

Two vaccines are available to protect females against the types of HPV that cause most cervical cancers. One of these vaccines also protects men and women against most genital warts. Whichever of these vaccines you and your doctor choose, you should stick with the same vaccine for all three shots.
Do I have to get the HPV vaccine?

The HPV vaccine is an important way for women to protect themselves against cervical cancer, which kills about 4,000 women each year in the U.S. It can also protect both men and women against genital warts. However, vaccination doesn’t protect against all HPV types that cause cervical cancers or genital warts. Whether you have to get vaccinated depends on your age and where you live. In certain states, girls within the recommended ages may need to get the HPV vaccine in order to go to school.

When should I get the HPV immunization?

The best time to get the HPV vaccine is before you’ve started having sexual activity. That’s why the CDC recommends that girls get their vaccination at age 11 or 12, although they can get the vaccine as early as age 9. If you’re 13 or older and you haven’t already been vaccinated, you can still get the vaccine up to age 26.

Although HPV vaccination is not on the recommended immunization schedules for boys and young men, they can get the Gardasil vaccine between ages 9 and 26 to protect them against genital warts.
If I’m over age 26, can I still get vaccinated?

The HPV vaccine isn’t recommended for people over age 26, because it hasn’t been studied well enough in this age group. If enough future studies show that it is safe and effective for people over 26, the FDA may eventually start recommending it for this age group.
How many shots do I need?

You’ll get three shots of the HPV vaccine over a 6-month period. You need to take all three doses to be completely protected. You’ll get the second shot about 1 to 2 months after the first, and the third shot 6 months after the first. Once you’ve started with a vaccine brand (Cervarix or Gardasil), stick with it for all three shots.
If I already have HPV, will this vaccine treat it?

No. If you have a current HPV, the vaccine won’t get rid of the infection. However, if you have one type of HPV the vaccine may prevent you from getting another type of the virus. There’s really no way to treat the virus once you have it, although there are treatments for diseases caused by HPV such as genital warts and genital cancers. This is why you should have regular pelvic exams and Pap tests (if you’re female) to screen for cervical cancer.
Does the HPV vaccine protect me for life?

You should be protected against HPV for at least 5 years; that’s how long the vaccine has been tested to work in studies. Longer-term research is needed to confirm exactly how much longer the protection lasts. Even women who are protected against HPV with the vaccine should see their gynecologist regularly for a Pap test to check for cervical cancer since the vaccine doesn’t protect against all HPV types that can cause cervical cancer.
Will my insurance cover the cost of the HPV vaccine?

Most insurance plans cover recommended vaccines, which means that if you’re a girl or woman ages 11 to 26, your insurance should pay for the vaccine. Check with your insurance company just to be sure. If your family doesn’t have health insurance or you’re on Medicaid, you should be able to get the HPV vaccine for free through the Vaccines for Children (VFC) program.

Is this vaccination safe?

Vaccines have to be rigorously tested before they can be widely distributed. Both HPV vaccines were tested on thousands of people and shown to be safe before they were released to the public. These vaccines have been used for several years now, and experts say the chance of them causing a serious reaction is very slim. You don’t need to worry about mercury or thimerosal with the HPV vaccine, either. It doesn’t contain these preservatives.
Is there any reason why I shouldn’t get this vaccine?

Some people shouldn’t get the vaccine. You definitely don’t want to get the HPV vaccine if you’ve had a serious allergic reaction to it or to any of its components, including baker’s yeast and latex. Let your doctor know if you have any severe allergies. Also talk to your doctor if you have an immune system problem or blood disorder.

If you’re pregnant, you’ll want to wait to get the HPV vaccine until after your baby is born. In studies, HPV vaccines didn’t cause any problems in babies whose mothers got the vaccine while pregnant, but pregnant women should not get HPV vaccine as safety studies are still ongoing.
Could I have side effects from the HPV vaccine?

You could have side effects, but if you do they should be mild. Most people who complain of symptoms after getting the HPV shot have minor issues like pain or swelling at the site of the shot, fever, headache, nausea, vomiting, diarrhea, abdominal pain, or muscle and joint pain.

Sometimes people faint after getting the HPV vaccine or any other vaccination. Sitting down after getting the shot can prevent you from passing out.
If I get the HPV vaccine, is there a chance I could get HPV?

No. The part of the HPV virus used in both vaccines is inactivated (not live) so it can’t cause actual HPV infection.

How Low Testosterone Affects Health, Mood, and Sex

Low Testosterone and Sex Drive

Testosterone isn’t the only fuel for a man’s sex drive and performance. But low testosterone can reduce your ability to have satisfying sex. Lack of sex drive and erectile dysfunction are sexual problems that can result from low testosterone. If low testosterone is the cause, treating it can help.
Testosterone and the Causes of Low Libido

Researchers haven’t unraveled the mystery of just how testosterone increases libido. It’s normal for a man’s sex drive to slowly decline from its peak in his teens and 20s, but libido varies widely between men. What one man might consider a low sex drive, another might not. Also, sex drive changes within each man over time and is affected by stress, sleep, and opportunities for sex. For these reasons, defining what’s a “normal” sex drive is next to impossible. Usually, the man himself identifies a lack of sex drive as a problem. Other times, his partner may consider it to be an issue.

Low testosterone symptoms don’t always include feeling like you have no sex drive. Some men maintain sexual desire at relatively low testosterone levels. For other men, libido may lag even with normal testosterone levels. Low testosterone is one of the possible causes of low libido, however. If testosterone is lowered far enough, virtually all men will experience some decline in sex drive.

In a large study of men in Massachusetts, about 11% overall said they had a lack of sex drive. The researchers then tested all the men’s testosterone levels. About 28% of men with low testosterone had low libido. These men were relatively young, with an average age of 47; older men might have worse sexual symptoms.

Low testosterone is only one of the causes of low libido. Stress, sleep deprivation, depression, and chronic medical illnesses can also sap a man’s sex drive.
Low Testosterone and Erectile Dysfunction

Surprisingly, low testosterone by itself rarely causes erectile dysfunction, or ED. Low testosterone alone — with no other health problems — accounts for a small minority of men with erectile dysfunction.

Erection problems are usually caused by atherosclerosis — hardening of the arteries. If damaged, the tiny blood vessels supplying the penis can no longer dilate to bring in the strong flow needed for a firm erection. Diabetes, high blood pressure, and high cholesterol are the three main causes of atherosclerosis and erectile dysfunction.

At the same time, low testosterone is a frequent accomplice to atherosclerosis in creating erectile dysfunction. In studies, as many as one in three men mentioning ED to their doctor have low testosterone. Experts believe that in men with other factors causing erectile dysfunction, low testosterone can strongly contribute, making a difficult situation even worse.

Strengthening the connection, low testosterone is linked in some way with many of the conditions that lead to erectile dysfunction:

Metabolic syndrome
Obesity
Endothelial dysfunction
Diabetes

Although low testosterone isn’t known to cause them, the associations between other medical conditions and low testosterone can be significant.

Testosterone therapy improves sex drive and satisfaction with sex in many men. However, the long-term risks and benefits of testosterone replacement are unknown. Research trials on testosterone replacement in men are ongoing, although results are years away.

Circumcision: The Surgery That May Lower Prostate-Cancer Risk

A new study suggests that men who are circumcised before their first sexual encounter may be less likely to develop prostate cancer later on.

As the study reports, sexually transmitted infections (STIs) are commonly linked to prostate cancer, since these conditions cause inflammation of the prostate — which makes it vulnerable to abnormal growth of cells. Circumcision, doctors theorize, could inhibit this cancer-causing pathway by getting rid of the foreskin that can harbor infections.

In the study, researchers from the University of Washington looked at surveys and medical records of 1,754 men with prostate cancer and 1,645 men without the disease. They found that those who were circumcised before they had sex for the first time were 15% less likely to develop prostate cancer than their uncircumcised counterparts. They were also 18% less likely to develop more-aggressive forms of the cancer.

The authors write:

The moist environment under the preputial skin may help pathogens survive for extended periods prior to direct infection. Combining the finding of a relationship between a history of STIs and [prostate cancer] risk along with a reduction in STIs in circumcised men has led to the hypothesis that circumcision might reduce [prostate cancer] development by decreasing prostatic exposure to infectious agents.

But that doesn’t mean that parents who do not circumcise their sons are putting their boys at risk for cancer. In fact, the American Academy of Pediatrics does not recommend routine circumcision, since the operation can cause complications and there isn’t strong enough evidence of the operation’s benefits to support those risks. The current results only highlight a correlation between the procedure and a lower risk of the disease, not a cause-and-effect relationship.

For now, the results are a first step toward better understanding the various factors that contribute to prostate cancer. Exposure to STIs, and the role that circumcision may play in lowering risk of those infections, might be an important component of the cancer, but it’s too early to label circumcision as a way to combat it. “That would be a huge jump,” Dr. Louis Kavoussi, chairman of urology at North Shore-LIJ Health System, told WebMD. “There are good reasons to get circumcised, but prostate-cancer prevention is not one of them.”

Which means that parents debating whether to circumcise their newborn baby boys still have a difficult decision to make about whether the operation is a good idea. The Centers for Disease Control and Prevention have not released recommendations for male circumcision but say that regardless of public-health recommendations, the decision will always be voluntary.

“At the end of the day, we feel there’s risks and benefits, and it’s up to the parents to decide what is in the best interests of their child,” Dr. Andrew Freedman, a pediatric urologist and member of the circumcision task force at the American Academy of Pediatrics, told MSNBC.

The new study was published online in the American Cancer Society journal Cancer.

Penis Size: It May Be Written in the Length of His Fingers

2012-03-05

The ratio of the length of a man’s index finger to that of his ring finger may seem like a strange thing to measure, but new research suggests that it’s linked with penis size. The lower the ratio, the longer the penis.

The new study was conducted on 144 Korean men who were hospitalized for urological surgery. A researcher measured the patients’ penile length — flaccid and stretched — just after they went under anesthesia for their operations. A different researcher measured the men’s finger lengths, in order to prevent knowledge of one measurement unconsciously affecting the other.

They data suggested that those with a lower ratio, whose index finger (or second finger, 2D) was shorter than the ring finger (or fourth finger, 4D), had a longer stretched penis length, which is well correlated with erect size.

“Based on this evidence, we suggest that digit ratio can predict adult penile size,” the researchers, led by Dr. Tae Beom Kim of Gachon University in Incheon, Korea, wrote.

Previous studies have linked the so-called 2D:4D ratio of finger length with exposure to the sex hormones estrogen and testosterone in the womb. So it’s plausible that the same exposure may affect penis length.

Higher testosterone levels during fetal development are associated with a lower 2D:4D ratio, while higher estrogen levels are connected with a higher one. Most men have index fingers that are shorter (low ratio) than their ring fingers, while most women’s index fingers are the same size or longer (high ratio) than their ring fingers. Research has shown, however, that lesbians and female-to-male transgendered people are more likely to have more “male” ratios.

Finger-length ratios have been linked previously with a variety of other characteristics: in both males and females, lower ratios are associated with better athletic performance. In men, one study found that a lower ratio was connected with more success at high-frequency financial trading, while another study associated it with better performance on medical school entrance exams; women were not included in those studies.

Men with lower 2D:4D ratios were also more likely to have more “masculine” features, to have more symmetrical faces, and to be considered attractive by women, according to another study.

Yet other research links low 2D:4D ratios with higher rates of alcohol consumption and alcoholism itself. Some data suggest that a more “female” finger-length ratio in men is associated with increased risk for oral cancer but reduced risk for prostate cancer.

In both boys and girls, lower and more “male” 2D:4D ratios have also been repeatedly connected with autism; interestingly, a recent study also found that female-to-male transgendered people are more likely to have autistic traits.

Of course, it remains to be seen whether the correlation between penis size and 2D:4D ratio holds true in non-Korean men or in Korean men who aren’t having some type of urological surgery.

But if so, digit ratio could be good for more than just a pick-up line at a bar. An easy and non-invasive measurement, it could give doctors a quick way to gauge how much testosterone their patients were exposed to in the womb, wrote Dr. Denise Brooks McQuade of Skidmore College in Saratoga Springs, N.Y., in an editorial accompanying the study.

The study was published in the Asian Journal of Andrology.

Eczema tied to higher impotence risk

2012-02-14

Men who have the allergic skin condition eczema may have a higher risk of erectile dysfunction than other men, a new study finds.

The study, of nearly 4,000 Taiwanese men with ED, hints at a connection between eczema and impotence.

And the researchers suggest that doctors “be more attentive to sexual complaints” from men with eczema — known medically as atopic dermatitis.

But an allergy expert not involved in the study said that while the findings are “interesting,” there are too many limitations to know whether eczema actually raises the risk of ED.
