The debate over circumcision status and HIV in the medical literature was started in 1986, when the New England Journal of Medicine published a letter from the late Aaron J. Fink, MD.
Fink was a California urologist, an outspoken advocate of circumcision who had self-published a book to promote his ideas about circumcision.
Fink maintained that the foreskin "increased infection by HIV." Fink claimed that the keratinization of the penis of the circumcised male reduced the chance of HIV penetration. There is no direct evidence to support this claim.
When you read the whole report, pay special attention as to where the study was conducted and who the subjects were.
When we compare circumcised males to intact males from Europe, who have a similar life style to ours, the intact come out way ahead in regards to having much less HIV/AIDS and other venereal diseases. That is the most reliable evidence because it is simply the way it is, it was not found due to a study looking for a certain outcome.
Such a publication as the Lancet has accepted several times is irresponsible. Besides promoting circumcisions it sanctions unprotected sex which is the real culprit in venereal diseases.
