Is this the G-Spot?
The press release proclaims “Study Confirms Anatomic Existence of G-Spot.” The study itself is titled “G-Spot Anatomy: A New Discovery.” It was just published in The Journal of Sexual Medicine. The author, Adam Ostrzenski, is an “internationally renowned gynecologic surgeon” with multiple degrees (MD, PhD, Dr Hab) and many peer-reviewed articles listed in PubMed.
The G-spot, or Gräfenberg Spot, is an area on the anterior wall of the vagina that can be stimulated to produce sexual excitement, stronger orgasms, and maybe even female ejaculation. Its existence is questionable. Wikpedia has an extensive article explaining the controversy and the published evidence, pro and con, with links to the original sources. You can read more than you ever wanted to know about it there, so I won’t bother trying to repeat it here. A 2012 review of the G-spot literature concluded:
Objective measures have failed to provide strong and consistent evidence for the existence of an anatomical site that could be related to the famed G-spot. However, reliable reports and anecdotal testimonials of the existence of a highly sensitive area in the distal anterior vaginal wall raise the question of whether enough investigative modalities have been implemented in the search of the G-spot.
Dr. Ostrzenski claims to have found the G-spot and taken its picture (above). Believers in Bigfoot and the Loch Ness monster have pictures too. They even had “Bigfoot hair” that later turned out to be synthetic wig fibers. Ostrzenski’s “proof” is no more credible than theirs.
A recent three-part article published in ACA News advocates turning chiropractors into “conservative primary care providers” who would be the initial point of contact for patients, would serve as gatekeepers for referrals to medical doctors and specialists, and would co-manage patients with those specialists on a continuing basis: essentially, family doctors. I think that’s a terrible idea. It might benefit chiropractors by increasing their market share, but it wouldn’t benefit patients. There is no evidence to indicate that chiropractors are capable of filling that role effectively or safely.
NUHS. The article was co-authored by several chiropractors on the faculty of the National University of Health Sciences, a school noted for integrating quackery with medicine. The “sciences” this school teaches are listed at the top of its website: chiropractic medicine, naturopathic medicine, oriental medicine, acupuncture, biomedical science, and massage therapy. The only one of those that even sounds like science, “biomedical science,” offers a bachelor of science degree with an integrative medicine focus and with no required core courses whatsoever!
Their doctor of chiropractic degree program says:
National University prepares students to become first-contact, primary care physicians fully qualified to diagnose, treat and manage a wide range of conditions.
Eric Topol, MD, has written a book about the convergence of the digital revolution and medicine. It is full of fascinating information and prognostication, but I wish he had given it a better title. He called it The Creative Destruction of Medicine: How the Digital Revolution Will Create Better Health Care. Medicine will not and cannot be “destroyed.” It will be improved and transformed, perhaps, but not destroyed. And any new developments will have to be evaluated for safety and effectiveness by the good old time-tested methods of science.
The future world of medicine is really exciting: science fiction is becoming real. As I read Topol’s book I serendipitously found it paraphrased by a character in another book I was reading, Chop Shop, by Tim Downs.
I see a world where no one ever dies from an adverse drug reaction; where physicians have an entire range of medicines to choose from to treat a deadly disease; where medications target tumors like smart bombs and leave surrounding tissues unharmed; where genetic susceptibility to disease can be determined in childhood, and possibly even prevented.
(If you haven’t yet discovered Downs’ hilarious “Bug Man” detective series about a crazy forensic entomologist, you have a treat in store.)
But back to non-fiction. Our world is changing almost too rapidly to comprehend: the Internet reaches everywhere, and there are far more mobile phones in the world today than toilets. We have hardly begun to tap the current potential of new technologies, and unimagined further developments await us. Topol is a qualified guide to this new world: he is a respected cardiologist and geneticist who ha s been on the forefront of wireless medicine and who was a major whistleblower in the Vioxx fiasco. He knows whereof he speaks, and he writes lucidly and accessibly.
Last week I wrote about a regrettable piece on homeopathy that was published in Scientific American Brasil. There have been gratifying developments. Within hours, the editor in chief of Scientific American, Mariette DiChristina, appeared in the Comments. She said that Scientific American does not condone the pseudoscience of homeopathy, that the piece clearly should not have been published, that it would never have been published if Scientific American had been consulted beforehand, and that she had complained to the responsible parties. I was very grateful for her response to my article, for her intervention, and for her willingness to speak out in support of good science.
Lo and behold, two days later Ms. DiChristina reported that the editor of Scientific American Brasil had written a letter of apology and had published it on the website. Here is a full translation:
I recently received an e-mail from one of SBM’s readers in Brazil, Felipe Nogueira Barbara de Oliveira, a PhD candidate in Medical Science who holds an MS in Computer Science and is who is trying to promote critical thinking and scientific medicine in his country. He sent me a jpeg copy of a short piece that was published (in Portuguese) in the April, 2012 issue of Scientific American Brasil. He was appalled that this appeared under the aegis of Scientific American, and so was I. He provided the translation which follows.
Warning: this is painful.
The Questioned Effectiveness of Homeopathy
Application of this technique in agriculture shows recuperation of plants and environment.
Homeopathy is known as an alternative treatment for human beings, but few people know about its utilization on animals, plants, soils, and water. This technique is the target of critiques regarding results and efficacy. One of them is about the “placebo effect” of its remedies, which do not contain any trace of the raw material used in its preparation. To answer this criticism, a clarification is necessary: homeopathy is not related to chemistry, but to quantum physics, because it works with energy, not with chemical compounds that can be qualified and quantified.

The 6th World Skeptics Congress will be held on May 18-20 in Berlin, Germany. Topics will include: Why do people turn to pseudoscience for help? What makes alternative medicine so attractive – and how can we find out what really works? Why is it so difficult for us to deal with risk and uncertainty in a rational way? Can we teach children to think critically and scientifically? And how can academic disciplines like biology or psychology protect themselves from pseudoscientific contamination?
Dr. Harriet Hall will be speaking on “CAM: Fairy Tale Science and Placebo Medicine.”

I know a woman who is a survivor of colorectal cancer. At one point, doctors had given up hope and put her in hospice, but she failed to die as predicted and was eventually discharged. She continues to suffer intractable symptoms of pain with alternating diarrhea and constipation. I don’t have access to her medical records, but she tells me her doctors have talked about irritable bowel syndrome (IBS) and have also suggested that the heavy doses of radiation used to treat her cancer may have caused permanent damage to her colon. Whatever the cause, her symptoms have seriously interfered with her mobility and her quality of life. Her health care providers have recently recommended questionable treatments in what I think can be construed as using CAM as a dumping ground for difficult patients.
Colonoscopy hadn’t shown any obstruction, but one of her doctors had hypothesized that her symptoms might be due to impaired bowel motility in the irradiated area. She was desperate enough to consider surgery if there was a chance that bowel resection or colostomy might improve her symptoms. She belongs to a large, well-known HMO with a good reputation. She asked her primary HMO physician who thought the idea was plausible and referred her to a surgeon. The first surgeon said surgery was not indicated and referred her to another surgeon on staff. In addition to being board certified in general surgery, the second surgeon was allegedly board certified in something related to CAM (my friend can’t remember his exact words and has been unable to verify any such credentials online).
The surgeon recommended acupuncture, not once but twice. My friend’s husband (who teaches statistics at a nearby community college) told the surgeon that he was fascinated by the challenges of double-blinded studies of acupuncture and that he was aware of no benefits beyond the placebo level. The surgeon then retreated a little and suggested that the primary benefit of acupuncture in treating IBS was the “relaxation” effect.
From an e-mail I received:
As a proponent of SBM, and a someone who places a high value on reason, logic and evidence, I would like to find a physician who shares this mindset.
He went on to ask how he could go about finding one.
Another correspondent was referred to a surgeon by her primary physician, and the surgeon inspired confidence until she started talking about using homeopathic arnica pills to improve healing post-op. How she could determine the technical competence of this surgeon? Was acceptance of homeopathy a reason to shed doubt on her judgment in other areas? Should she seek a second opinion?
I get a lot of inquiries about how to find a good doctor. I don’t have a good answer. I thought it might be useful to throw out some ideas that have occurred to me and hope that readers will have better ideas and will share their experiences about what has or hasn’t worked. (more…)
I’ve already devoted more time to Protandim than it deserves. I’ve written about it twice on SBM: here and here . But I can’t resist covering a new Protandim study that not only serves as a bad example but that made me laugh.
Protandim is a mixture of 5 herbal supplements intended to upregulate the body’s own production of antioxidants. Its patent application claimed that it was useful to treat or prevent an astounding 126 diseases and medical conditions, from tinnitus to aging, from hemorrhoids to cancer. At the time of my last article, only one human study had been done. It found increases in blood test markers and interpreted them as a surrogate for increased antioxidant activity in the body, but did not even attempt to assess whether those increases corresponded to any measurable clinical benefit, for cancer or for anything else. I begged Protandim supporters not to ask me about it again until there were human clinical studies with meaningful outcomes.
Now there is finally a second human study, although still not one that qualifies as a clinical trial. Curiously, it is not listed on the company’s website. I wonder why? Perhaps because it showed Protandim didn’t work. Oops.
Two weeks ago I wrote about the demise of the traditional annual physical for healthy adults who have no symptoms.
The First Step: Identifying a Symptom
People who do have symptoms should see a doctor. They should have appropriate evaluations that may or may not include a partial or complete physical exam. One problem is that people may not be able to decide what qualifies as a significant symptom. Could the heartburn actually be a heart attack? Is the fatigue a normal result of exertion, or could it be a sign of something serious? Could my headache be a sign of brain tumor, or should I just take an aspirin? My spouse says I’ve been snoring more: could that be a sign of sleep apnea? What if I just “don’t feel right”?
This is a real dilemma, because minor transient symptoms are a normal part of life. Some of them are due to trivial conditions that spontaneously resolve; some are sensations due to the normal functioning of the body. Some people are more aware of these sensations than others. Paying attention to them tends to make them worse. Some people barely let these minor sensations intrude on conscious thought; others fixate on them and obsess about them. There is a spectrum of human reactions ranging from the stoic denier to the hypochondriac. (more…)
