Depo Provera May Be Linked To Higher HIV Risk.

Previous studies suggested that Depo, which is made up of a hormone that mimics the reproductive hormone progesterone, was linked to higher risk of infection, but other studies showed conflicting results. Ralph found that only Depo was associated with a higher risk of HIV infection; there was no similar increase among women using the pill, which is composed of two hormones, estrogen and a form of progesterone. The correlation remained even after they considered potentially confounding factors, such as the women’s condom use. While the study didn’t address the reason for the difference between oral contraception and Depo, some research suggests that their differing hormone combinations may have varying effects on the structure of the genital tract, a woman’s immune response or her vaginal flora, all of which could influence her vulnerability to acquiring HIV. http://time.com/3660564/contraceptives-hiv-risk/
