OPINION: Circumcision study was ‘poor science’

By Dr Howard Cohen, who is a Mohel for the London and South East UK Jewish community and an officer of Liberal JudaismDr Howard Cohen-1

An article published last Friday online by Frisch and Simonsen, claiming ritual circumcision doubles the risk of autism spectrum disorder, certainly caught our attention and that of the national press. 

As a GP and a mohel (a ritual circumciser) for more than 20 years, a father of an autistic son and the step father of another it was a bit too close to home. My initial response was a feeling of dread that our choice to circumcise our new born sons in accordance with our tradition could have harmed them in any way – that our sons’ lifelong disabling condition could have been the result a single ill-advised event.

Coping with a diagnosis of autism brings with it the recurring cycle of parental self-doubt and guilt triggered by others’ opinion or poorly conducted research. From the discredited theories of Bruno Bettleheim that autism arose from emotionally frigid parenting to the unfounded concern over the MMR vaccine, autism history has been littered with erroneous theories of causation, laden with censure and blame. These left parents bewildered, saddened and with little hope or even a preventative strategy to at least avoid parenting more disabled children in the future.

In addition, the paper triggered an understandably defensive response. Outsiders questioning circumcision is guaranteed to unite even our fragmented Jewish community in a robust rebuttal and in this case rightly so. It is hard not to respond to this paper simply as an attack on Jews and Muslims and our practices.

This is poor science.

The wrong type of study was done to explore whether a causative link exists. Observational studies can suggest associations but cannot explain the mechanisms of diseases. The authors seemingly failed to grasp both what autism is or what happens at a circumcision.

The complexity of the autistic brain with it challenges and on occasion wonders, so clearly arises from the combination of numerous factors, most of which are currently poorly understood. The single trigger theories, whilst superficially attractive are merely illusions which fade on close inspection. 

The paper views all circumcisions as the same, whether on day eight or year eight, with or without suitable anaesthetic or analgesia. It plays into the prejudicial stereotype that the circumcision is a hugely traumatising event for the baby, accompanied by unimaginable pain and suffering. This is so clearly not the case, no parent would let the mohel through the door if it were, let alone invite them back which successive sons and grandsons.

As a Mohel, over the last 23 years I have circumcised new born boys, usually within the first twenty eight days of birth, always with a suitable local anaesthetic. As a Liberal Jew, I have learnt to question all our traditions, including Brit Milah.

Quite separate to this article, there is no need medically or religiously, to hurt a baby and I would be at the head of a campaign to stop the practice if we showed it caused harm. This article does not and could not make that case.

It does however raise a question, which is the role of observational research; it is for us to answer in a clear calm and reasoned way. That is the challenge for us all in the Abrahamic Tradition who are called upon to circumcise our sons.

    This is the second peer-reviewed study to find a correlation between infant circumcision and autism/ASD. This needs to be followed up as a matter of urgency rather than dmismissed as “poor science”. If the same results are found elsewhere, then it seems highly likely that a number of cases of autism could be prevented simply by not circumcising, or possibly doing it later in life, or by using general anesthetic during the operation or different pain relief for post-operative pain (it could be paracetamol causing the problem).

    It’s worth noting that people who circumcised their sons tend not to question observational studies that show potential benefits to circumcision, even where no mechanism has been proposed.

    The studies are here:

    Bauer, Kriebel, 2013
    http://www.ncbi.nlm.nih.gov/pubmed/23656698
    “For studies including boys born after 1995, there was a strong correlation between country-level (n = 9) autism/ASD prevalence in males and a country’s circumcision rate (r = 0.98). A very similar pattern was seen among U.S. states and when comparing the 3 main racial/ethnic groups in the U.S.”

    Frisch, Simonsen, 2015
    http://jrs.sagepub.com/content/early/2015/01/07/0141076814565942.abstract (free to download)
    “Results: With a total of 4986 ASD cases, our study showed that regardless of cultural background circumcised boys were more likely than intact boys to develop ASD before age 10 years (HR = 1.46; 95% CI: 1.11–1.93). Risk was particularly high for infantile autism before age five years (HR = 2.06; 95% CI: 1.36–3.13). Circumcised boys in non-Muslim families were also more likely to develop hyperkinetic disorder (HR = 1.81; 95% CI: 1.11–2.96). Associations with asthma were consistently inconspicuous (HR = 0.96; 95% CI: 0.84–1.10).”

    In the words of the recent study:
    “These findings obviously do not prove the suggested associations. However, in combination with recent animal studies showing lifelong deficits in stress responses following exposure to just one single neonatal insult, the observed strong correlation between circumcision and ASD prevalence, and clinical observations of long-term changes in pain perception in circumcised infants, our population-based findings should prompt other researchers to examine the possibility that circumcision trauma in infancy or early childhood might carry an increased risk of serious, yet hitherto unappreciated negative neurodevelopmental and psychological consequences.”

    How could circumcision not be harmful? If you were forcefully restrained and were subjected to having a part of your genitals cut off, that would be harmful. Because infants are more sensitive to pain and trauma, it is also harmful to them. Let’s remember the Golden Rule.

    Studies show that circumcision causes significant pain and trauma, behavioral and neurological changes in infants, potential parental stress from persistent crying (colic) of infants, disrupted bonding between parent and child, and risk of surgical complications. Other consequences of circumcision include loss of a natural, healthy, functioning body part, reduced sexual pleasure, potential psychological problems, and unknown negative effects that have not been studied.

    Some circumcised men resent that they are circumcised. Sexual anxieties,
    reduced emotional expression, low self-esteem, avoidance of intimacy, and
    depression are also reported. Some doctors refuse to perform circumcisions because of ethical reasons. Relying on presumed authorities (e.g., American Academy of Pediatrics or doctors who echo AAP views) is not sufficient because of their personal, religious, financial, and political conflicts of interest.

    The problem is that those who circumcise generally refuse to seriously consider the harm because it would be emotionally disruptive and reflect on themselves (if male) and their decision to circumcise and harm a son. They do not have an open mind on the subject. Fortunately, a growing number of Jews choose not to circumcise and they find rabbis who support their choice. See http://www.jewishcircumcision.org .

    “Quite separate to this article, there is no need medically or religiously, to hurt a baby and I would be at the head of a campaign to stop the practice if we showed it caused harm. This article does not and could not make that case.”

    But of course, whether related to autism or not, circumcision DOES do harm. It irreversibly alters the baby’s genitals without his consent. It removes highly innervated, living, healthy and highly functional erogenous, protective and immunological tissue. His body, his choice! Let the boy decide when he is of age, and has ALL the information. Perform a lovely and peaceful Brit Shalom, a symbolic, welcoming ritual, which ensures the baby is left intact, the way nature intended. See http://www.BeyondtheBris.com.

    Frisch is a well-known Danish anti-circumcision activist. His previous research attempting to find adverse effects of male circumcision has been discredited. His new publication in a low-ranked journal should ring alarm bells, given the history of other false links to autism. Dr John Wakefield was struck off the medical registry when his paper linking childhood vaccination to ASD was subsequently shown to be fraudulent.

    In the new study, Frisch and Simonsen performed a “data dredging” exercise of the public medical records of 342,877 boys in Denmark looking for any adverse medical condition they could associate with circumcision. Although they found a slight excess of ASD in circumcised boys, the numbers were trivial. In the largest population group in Denmark in which boys receive a circumcision – Muslims – the excess was only 10 boys! … and the statistical significance was marginal. The association applied only to ASD diagnoses in infancy. In non-Muslim boys there were only 6 with autism. One should question the statistics used, given that the enormous number of ASD cases in the control group.

    Frisch speculates, without evidence, that the reason for the associations found had to be “pain” caused by circumcision, even though local anesthesia is recommended and surveys show only a tiny proportion of boys experience pain (probably indicating that the anesthetic was inadequately applied).

    Frisch & Simonsen ignore data from a study in 2013 that showed an association of ASD with the upswing in paracetamol use after 1995 [Bauer et al. Environ Health 2013;12:41]. That study used infant circumcision as a proxy for paracetemol use (the mid-1990s being the time that analgesia post-circumcision became a recommendation). The Bauer study pointed out that in infancy (only) the metabolism of paracetamol in the body results in generation of toxic degradation products that can cause neuronal damage in the still-developing brain, so potentially contributing to ASD in a small proportion of susceptible infants. But the authors of that study emphasized that the association was juts that, and did not imply a causal link.

    Frisch & Simonsen also ignore data showing anesthetic use in children under 3 years of age (which is not advisable for a trivial procedure such as circumcision, but is nevertheless used by some medical practitioners for convenience) also has the potential to increase risk of neuronal damage, based on the detection of cognitive defects at age 10 in such children [Ing et al. Pediatrics 2012;130:e476-85]. But again, that study emphasized that other factors could be explaining the association. Importantly, newer anesthetics are less likely to cause such problems, so that problem may be historic only.

    If Frisch & Simonsen were actually concerned about pain in childhood being a cause of ASD then they would have studied well-known causes of pain. It is well-known that urinary tract infections (UTIs) cause excruciating pain. Since UTIs are common and the rate of UTIs is 10 times higher in uncircumcised infant males, in the unlikely event that their hypothesis were correct then they would have seen an association of LACK of circumcision with ASD!!! But they didn’t look (or at least one suspects, given the general obfuscation that appears in their article, if they did find any association that pointed to yet another adverse effect of lack of circumcision then one might expect that they would be reluctant to reveal it, as it would undermine their anti-circumcision agenda. Even then, any association could be from paracetamol use for pain relief.

    They cite a study by other circumcision opponents, Bollinger and Van Howe, claiming “circumcision trauma” causes alexithymia, but fail to cite the devastating critique of that study that was published in the same journal.

    Finally, the mere increase in contact with the medical system by parents seeking a circumcision for their boy will elevate the chance of DIAGNOSIS of ANY medical condition that the doctor might perceive to be present, but which the parents were unaware of. That would obviously include ASD.

    Thus, for many reasons, the conclusions by Frisch & Simonsen are highly speculative, biased (just as the rhetoric, selective citation and bias contained in their article), have alternative explanations unrelated to so-called “circumcision pain”, and are by an author (Frisch) who has a history of discredited research, and whose attack on the American Academy of Pediatrics affirmative infant male circumcision policy backfired when the AAP Task Force responded to point out the bias against circumcision was evident in Europe, but not in the USA.

    Therefore these new findings by Frisch should be viewed with extreme scepticism.

      Brian Morris has no real competence in epidemiology, andrology, human sexuality and theriogenology, venereology, anatomy, embryology, physiology, urology, paediatrics, soft tissue surgery or medical ethics, so also he has no competence whatsoever in human health risk assessment. He is an MD wannabe who was forced to spend his career eking out a living as a professor of cell biology. His efforts to make forced infant circumcision compulsory in the US are a world class laughing stock following his dismal failure to achieve the same in Australia.

      The Australians showed him where to get off. Vernon ‘Pretty Boy’ Quaintence has been incarcerated. And Mona Choi’s website has been yanked so it’s back to his old ad hominem attacks, big footnote fallacies and plain old BS. What Morris hates most about Morten Frisch is that not only is he a Ph.D (like Morris), but also an MD, something Morris himself could never (will never) achieve.
      When this world class Australian buffoon is reduced to stand up comedy, do check him out. He needs all the help he can get.
      Note well: If Morris had anything of import to say he would do so in a scholarly article in a peer reviewed journal. Not in the comments section of an internet article.

      Brian Morris wishes that Morten Frisch’s work was discredited.
      Morris should know what it feels like to be discredited. His work was specifically not cited by the CDC in its recent attempt at a pro-circumcision recommendation, though many of his co-authors were cited. The RACP in his home country of Australia has repudiated his views on circumcision, as have medical societies in New Zealand.
      See the youtube video War on Circumcision, for a spoof using his words.

      • professormorris

        The CDC **DID** cite me, specifically my pivotal 2014 risk-benefit analysis of infant male circumcision in Mayo Clinic Proceedings showing benefits exceed risks by 100 to 1, even though the CDC aimed to only cite publications that came out prior to the end of 2012. So then Adam is it that you didn’t actually read the CDC’s report?

        • Jacob Lorensen

          Benefit vs. risk is nonsense in regards to infant circumcision, and you know it. There are NO *directly* relevant benefits for an infant, or under age boy. On the contrary, it should be benefit vs. loss or bvenefit vs. harm.

          Zero benefit vs harm and definitely loss of a highly sensitive erogenous tissue.

          If there are directly relevant benefits to under age boys – please cite them. Your papers and others that I have read fail to cite a SINGLE benefit *relevant* to the under age boy.

          UTIs – NO! Anti-biotics work on girls as well as on boys.

          STD/HIV protection – seriously? Would that at all be a relevant benefit? Children are not exposed to unprotected penetrative sex with frequent, changing and unknown partners – I should hope!

          etc. etc.

          The only paper I’ve seen till now that mentions any so called benefit remotely relevant to an under age boy is “foreskin stuck in zippers”. Which only goes to show how low one needs to go in order to find any argument that may remotely justify forced circumcision.

          Just a single benefit *directly* *relevant* to an under age boy? Hmmm?

          Translation: Cherry picks flawed pro-circ studies and ignores rigorous, objective studies showing circumcision to be harmful.

          Why didn’t you just become a Catholic Priest, Brian?

          Does your wife put padlocks on your son’s bedroom door at night? No? She still doesnt’ know?

  • EuropeanMan

    This entire article written by Dr Howard Cohen can be summarized in one single sentence: “Religion and science do not always agree.” Sorry, just because a religion demands it or has demanded it for a long time is no guarantee that it is not harmful. Whoever claims that circumcision is not harmful is denying a fact: circumcision removes erogenous tissue causing to an infant excruciating pain. How can that be a good thing?

  • PeterLondon

    Dr Howard Cohen: An unbiased commentator! LOL

  • Rebecca Fine

    If circumcision increases the risk of autism, then wouldn’t Jewish boys have a higher rate of autism than amongst the general population?

    I’ve never seen any research or evidence to indicate that Jewish boys have more autism than boys of other groups.

    • Jacob Lorensen

      If I remember the paper correctly, they got the idea for their study from such a purely correlation-based study in USA that found this astounding *correlation*. To further analyse, they designed their study on danish data where there it was possible to do a cohorte study (as I understand it), where the same individual and his or her medical history can be followed over several years.

      Ie the paper demonstrated that there is a higher prevalence of ASD in the boys that are circumcised. Which is stronger than a mere correlation between rate of circumcision and rate of ASD. But not, and they point this out clearly, any causation explanation.

    • Lawrence Newman

      Well a confounding variable is the severity of circumcision. Many Jewish boys are circumcised Brit Milah which, though wrong and damaging, isn’t anywhere near the devastation the more popular form of circumcision, periah, causes. PEriah turns the penis into a numb dildo because it removes all or almost all of the foreskin–including all of the primary sexual tissue, the ridged band and frenular delta. (I know because this was done to me at 14, and histological analysis has confirmed what I’m saying.)

      I myself have PTSD and alexithymia because of how devastating this barbaric procedure was.

    So then stop doing it.

    Well.
    A british Judge concludes its “significant harm”…

    “Female genital mutilation has no known health benefits.”–WHO

    See, organisations like the WHO make completely incorrect statements like this. When it comes to male genital mutilation, we’re meant to believe it’s the cure of a thousand different diseases, but FGM has no benefits? Really? Wrong. Cutting off the glans clitoris prevents glans clitoral cancer. See. There’s a benefit.

    Also, a study suggested FGM reduces HIV risk. As much evidence as there is that MGM does. Must be ok, right?

    The doubletalk constantly carried out by so-called professionals on this , is disgusting.

    Do you even know what conflict of interest means, mohel?
