Male circumcision protects women from infections and cancer

U.S. rates of sexually transmitted infections (STI) are soaring to such an extent that public health officials are posting billboards that exhort sexual partners to use condoms.
Researchers are now also championing male circumcision as a mechanism to protect women. A recent study shows that male circumcision is “a powerful tool” to reduce women’s risk of cervical cancer, oncogenic human papillomavirus (HPV), bacterial vaginosis, and Trichomonas vaginalis, an STI.
Evidence is mixed, but encouraging, that circumcision is effective against chlamydia and syphilis, but is lacking in protection against gonorrhea, the researchers found.
The decline in the U.S. circumcision has paralleled the increase in populations whose cultures don’t normalize the procedure, said analysis co-author John Krieger, a professor emeritus of urology at the University of Washington School of Medicine. There also is an active anti-circumcision lobby, he said, that — as with opponents of immunization — ignores scientific evidence and instead disseminates myths, anecdotes, and disproven claims.
Still, if more women knew that male circumcision was shown to lower their risk of disease, wouldn’t they be clamoring — as sexually active adults and as mothers and sisters of boys — for male circumcision?
In that context, it is disconcerting that the U.S. rate of male-newborn circumcision declined from about 65 percent in 1979 to 58 percent in 2010, according to the Centers for Disease Control and Prevention. Some nations have far lower male-newborn circumcision rates — about 14 percent in China and India, and 5 percent in Sweden, a 2016 study reported.
In 2012 the American Academy of Pediatrics issued a policy statement that circumcision’s health benefits substantially outweighed its risks, but also noted cultural sensitivities were more important for some parents, so their recommendation fell short of universal newborn circumcision.
Krieger said that position should be changed in light of this new review of the literature.
Vaccinations are lowering the risk of future generations’ exposure to certain HPV types, but the declining prevalence of male circumcision can only increase global rates of cervical cancer, Krieger said. Women should wield their “considerable power” to influence decisions to circumcise the males in their lives, he and his co-authors summed up.
