Baby’s DNA in Mom’s Blood: Noninvasive Prenatal Testing

Until recently, the moment of birth was a surprise. We anxiously awaited the obstetrician’s announcement: “It’s a boy!” or “It’s a girl!” Then we checked to see if any crucial parts were missing and we counted the fingers and toes. We had to wait for a baby to be born before we could know its sex and whether it was normal. Today,...

Autism and Induced Labor

A recently published epidemiological study in JAMA Pediatrics looked at the association between induction and enhancement of labor and the risk of autism. The researchers found a positive association, especially with males. The study has been variously reported in the popular press with causal interpretations not justified by the data. The study itself is very robust – the authors looked at 625,042...

Human Sex Determination: Psychic Sperm and the Gambler’s Fallacy…..

Carl Sagan supposedly once said that randomness is clumpy. Those three words have become one of my favorite go-to quotes, particularly when teaching residents and medical students who are often overly impressed with improbable runs of similar diagnoses or exam findings. I love this quote because it is so simple and yet reveals so much about our experience with observing the natural...

The Business of Baby and the Monkey Business of Margulis

A correspondent asked for my opinion of a new book by journalist Jennifer Margulis that is apparently getting a lot of attention in some circles: The Business of Baby: What Doctors Don’t Tell You, What Corporations Try to Sell You, and How to Put Your Pregnancy, Childbirth, and Baby Before Their Bottom Line. I got a copy from the library and read it....

The Bendectin Controversy Redux?

When I read that a new study had shown that antihistamines were harmful for patients with morning sickness, I cringed and thought “Here we go again.” Hyperemesis gravidarum (HG) is a serious complication of pregnancy. Simple morning sickness is more common and less serious. When I started out in medicine, we routinely treated morning sickness with Bendectin. It was a safe and...

Kudos to a Journalist

Many SBM readers will remember the late, great Barry Beyerstein,  a luminary of the skeptical movement and author of a classic article that has been cited many times on SBM, an explanation of why bogus therapies seem to work. One of his greatest personal accomplishments is not as well known: he produced an exceptional daughter, Lindsay Beyerstein, a freelance writer, philosopher, and...

G-Spot Discovered? Not So Fast!

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...

Acupuncture, Infertility, and Horrible Reporting

An article (and associated news video clip) from ClickOn in Detroit is titled “Alternative treatment helps Michigan doctor beat infertility.” This is a misleading title, and the report is an example of poor science reporting. Was she infertile? The patient in question was a 33-year-old family practice doctor who believed she was infertile. By definition, infertility is failure to conceive after a...

Birth Control

From a message posted on Facebook:  Is the pill safe? The International Agency for Research on Cancer in a 2007 study made by 21 scientists reported that the pill causes cancer, giving it the highest level of carcinogenicity, the same as cigarettes and asbestos. It also causes stroke, and significantly increases the risk of heart attacks. Several scientific journals have stated that...

Menstrual Synchrony: Do Girls Who Go Together Flow Together?

When women live together, do their menstrual cycles tend to synchronize? It’s been a long time since I first heard that claim. I didn’t believe it, for a number of reasons. I had never observed it myself, I saw no plausible mechanism to explain how it could happen, I thought the statistics to prove it would be problematic and complicated, and I...
