Promising trials hinted that circumcision could lower rates of HIV infection, but until now, researchers didn’t fully understand why.
Now, in a study published in the journal mBio, scientists say that changes in the population of bacteria living on and around the penis may be partly responsible.
Relying on the latest technology that make sequencing the genes of organisms faster and more accessible, Lance Price of the Translational Genomics Research institute (TGen) and his colleagues conducted a detailed genetic analysis of the microbial inhabitants of the penis among a group of Ugandan men who provided samples before circumcision and again a year later. - Yahoo!
