Some recent studies suggest the use of DMPA (depot medroxyprogesterone acetate, also known by the brand name Depo-Provera) may increase women's risk for HIV. The injection-method birth control is comprised solely of progesterone (versus other combination methods that use estrogen as well). Some studies have shown the progesterone in the birth control to negatively affect immune function, while others show no effect.
Either way, WHO (the World Health Organization) upholds their guidance on hormonal birth control and HIV, concluding that women living with HIV or at high risk of HIV can safely continue to use hormonal contraceptives to prevent pregnancy.
