How Effective?

Effectiveness depends on the user: Risk of pregnancy is greatest when a woman is late to start a new ring.

• The combined vaginal ring is new, and research on effectiveness is limited. Effectiveness rates in clinical trials of the vaginal ring suggest that it may be more effective than combined oral contraceptives, both as commonly used and with consistent and correct use (see Combined Oral Contraceptives, How Effective?).

Return of fertility after ring use is stopped: No delay

Protection against sexually transmitted infections: None
