Fertility Regulation in the Setting of HIV: What are the Controversies? Jane Hitti, MD, MPH University of Washington
Controversy #1 Aren’t condoms sufficient contraception for HIV-affected heterosexual couples?

Dual protection for HIV-positive women • HIV-positive women are more likely to use condoms consistently and less likely to use other methods of contraception • Reliance on condoms as a primary contraceptive method increases risk of unintended pregnancy
Controversy #2 Are other methods of contraception safe for HIV-infected women, particularly those on ART?

Controversy #3 Why do ART clinical trials and roll-out programs need to be concerned with family planning? (Can’t someone else do this?)

Contraception to Prevent HIV Sequelae • Effective contraception for HIV-infected women who do not wish to become pregnant prevents more infants from becoming infected than single-dose NVP, and also decreases the number of future orphans • This remains the BEST KEPT SECRET in HIV prevention • We urgently need more research on optimal contraceptive approaches for HIV-infected women Cates, Sex Trans Dis 2004;31:3-7
