One potential way that
the penile microbiome can increase HIV risk is by triggering production of immune factors that lure HIV target cells to the penis.
Earlier studies have linked the human microbiome — that is, the collection of microbes living in and on the human body — to a variety of health conditions, but little is known about the role of
the penile microbiome as it relates to men's health.
To better understand how
the penile microbiome differed between men who did and did not become HIV - infected during the trial, 136 men who remained HIV - uninfected during the two - year trial (controls) were also studied.
