A range of contraceptive methods are available to prevent pregnancy. There are traditional methods and modern methods, each with particular advantages and disadvantages. Traditional methods include the calendar method (also called the rhythm method) and withdrawal, both methods are behavioral and have no medical intervention. There are a range of modern methods, the most common use reproductive technologies that either create a barrier or use hormones to prevent pregnancy. In the United States, most modern methods require a prescription from or visit to a healthcare provider. Considered the most effective methods are female and male sterilization and long-acting reversible contraceptions (LARCs) which are hormonal or copper IUDs and implants. These most effective methods require a procedure from a provider and then no action by the user on a daily basis. Sterilization is permanent and LARCs can last for 3-12 years depending on the type used. LARC can be removed at anytime, including before they expire. Moderately effective modern methods include injectables, progestin-only pills, combined pills (contain estrogen and progestin), the patch, ring, and diaphragm. Less effective modern methods include male condoms and female condoms, however condoms are the only form of contraception that prevents the transmission of sexually transmitted infections (STIs). Because condoms prevent STIs, providers often counsel patients to use dual methods, condoms and another more effective method, this both prevents STIs and further decreases the likelihood of method failure and pregnancy. If a method was not used during vaginal-penile sex, or if a method failed (for example, condom broke) or was not used as directed (for example, pills were missed or delay in putting on a new patch), there are four forms of emergency contraception. In order of effectiveness, the four methods of emergency contraception are: the copper IUD (which then continues being used as an effective form of contraception for up to 12 years), antiprogestin pills, levonorgestrel pills, and combined oral contraceptives according to the "Yuzpe method."
