Considering the previous studies and the fact that this particular study has yet to be peer reviewed or even published, suggests that it’s a little premature to make the suggestion in the OP.
I’d like to see the data on this experiment. Also hope it includes the sexual activities of both the cut and uncut participants and their demographics. I don’t care if they were randomly chosen or not. If the majority of the uncut males were highly sexually active, never practiced safe sex, and lived in an area where the population had higher percentage of HIV, then there’s other things at work here.
I want to hear about the other variables in the experiment and see if they stayed controlled or if they think simply “randomly selecting” the males would average it all out.
If they randomly selected men, ordered them to use no condoms, and then made them have sex at least twice a month to a new person, then the results might mean something to me.
… anyway. I’ll wait to read this once it’s published.
