What is the primary benefit of using Depo-Provera?

The primary benefit of using Depo-Provera is that it provides long-lasting effects with a single injection. This contraceptive method works by delivering a synthetic form of the hormone progesterone, which prevents ovulation for up to 12 to 14 weeks after administration. This means that individuals do not need to remember to take a pill daily, making it a convenient option for those seeking effective birth control without the need for frequent action.

The duration of effectiveness allows users to maintain contraceptive protection without the ongoing effort required by some other methods. This entry points to the benefit of long-term planning and ease of use, making it a favored choice for many people looking for reliable contraception.

The other options are less aligned with the primary purpose of Depo-Provera: it does not provide immediate protection against STIs, is not a non-hormonal method, and while fertility can take some time to return after the last injection, it is not a method associated with quick reversal of fertility.
