What is the failure rate for the Depo-Provera contraceptive method?

The failure rate for the Depo-Provera contraceptive method is generally considered to be around 6% with typical use. This means that about 6 out of 100 women may become pregnant within the first year of using the injection as their contraceptive method. The effectiveness of Depo-Provera is highly reliant on adherence to the injection schedule, with the shot needing to be received every 12 weeks. When administered properly, it provides a reliable form of contraception and is one of the more effective hormonal methods available.

In comparison to the other choices, a lower failure rate (like 1% or 3%) typically refers to methods like IUDs or sterilization, which are more effective than hormonal injections. Even though 9% is a possible failure rate cited for some hormonal contraceptives, it reflects a higher rate than what is associated with Depo-Provera, thus supporting that the best-supported figure for typical use aligns with 6%. This clarifies that while the method is effective, it still requires compliance to maintain its contraceptive reliability.
