The author of the WSJ piece, Diane Cole, had her facts completely backwards, and the editors failed to fact-check.
To date, the only randomized controlled trial (RCT) to look at male-to-female HIV transmission and circumcision was halted early on ethical grounds because preliminary results showed up to a 54% higher risk of seroconverting among female partners of circumcised men. Simply put, this trial essentially negated any possible female-to-male benefits of male circumcision demonstrated in the 3 published RCTs on the subject.
The study was done in the Rakai region of Uganda. The lead researcher and author was Maria Wawer, wife of Dr. Ronald Gray of Johns Hopkins University, who was study designer of one of the three published RCTs. Dr Wawer is Canadian and Dr Gray is Australian; both are well-documented, outspoken proponents of male infant circumcision, even long before the studies were planned. Dr Wawer can be found in a YouTube interview laughing and pitying intact boys.
It was most unfortunate that the Journal chose to run this misleading piece.
