For many years, scientists have tried to answer several questions about whether various hormonal contraceptive methods (i.e., pills, injectables, implants, hormone-releasing IUDs, patches, and vaginal rings) impact various HIV-related risks. Key questions on this subject include:
The first question is the most controversial, and is a critically important question for women's health - particularly for those living in high HIV prevalence countries, including many in Eastern and Southern Africa. However, for a number of methodological reasons (many of which are detailed in this paper), it is extremely complex to design studies that will provide definitive answers.
- Are HIV-negative women who use specific methods of hormonal contraception more likely to acquire HIV?
- Are women living with HIV who use specific methods of hormonal contraception more likely to transmit their infection to a male sexual partner?
- Are women living with HIV and using specific methods of hormonal contraception likely to experience faster clinical disease progression?
- If a woman living with HIV is using antiretroviral therapy (i.e., medications to treat HIV), will using any specific method of hormonal contraception result in drug interactions. In other words, could using both medications at the same time make either medication less effective, or more likely to result in side effects?
