Which statement is NOT true regarding forms of contraception?

The statement that not all intrauterine devices (IUDs) provide long-term contraception for 8 years highlights an important aspect of contraceptive diversity and effectiveness. While some IUDs, specifically hormonal types, can provide effective contraception for up to 6-8 years, there are also copper IUDs, such as ParaGard, which can last up to 10-12 years. Therefore, the idea that all IUDs have the same duration of effectiveness is inaccurate; variations exist based on the specific type of IUD used.

In contrast, the other statements accurately reflect current knowledge about contraceptive methods. Implanon, a type of hormonal implant, is indeed effective for about 5 years, providing reliable long-term contraception. Medroxyprogesterone, administered via injection, provides effective contraception for approximately 3 months before a subsequent dose is required. Furthermore, contraceptive injectables may delay the return of fertility after discontinuation, which is a known consideration when discussing the use of this method, as it can take some time post-injection for ovulatory cycles to resume.

Understanding these distinctions helps clarify the options available in contraceptive methods and reinforces the necessity of consulting healthcare professionals for personalized advice tailored to individual circumstances.
