Family Health International's oral contraceptive research spans decades. We have explored the effect of oral contraceptive use on the acquisition of sexually transmitted infections (STIs), studied method pregnancy rates, continuation rates, reasons for discontinuation, and user knowledge of correct use. An FHI-led study found that using hormonal contraception, including oral contraceptives (OCs), does not appear to increase women's overall risk of infection with the AIDS virus. Additionally, we have worked with programs to improve provider knowledge and service delivery skills related to OCs.
When used consistently and correctly, OCs are among the most effective methods of contraception. They are highly popular throughout the world and can be safely used by the vast majority of healthy women. The contraceptive effect of OCs is reversible: when pills are discontinued, fertility returns quickly, making them ideal for delaying and spacing pregnancies. Furthermore, OCs have many noncontraceptive health benefits.
Combined oral contraceptives (COCs) that contain synthetic forms of the female hormones estrogen and progestin, are the most widely used oral contraceptives. But progestin-only OCs, known as POPs, are often a good contraceptive option for women who are breastfeeding. Certain regimens of OCs can be used for emergency contraception, that is, to prevent pregnancy soon after unprotected intercourse has occurred.
