Methods of contraception include oral contraceptive pills, implants, injectables, patches, vaginal rings, Intra uterine devices, condoms, male and female sterilization, lactational amenorrhea methods, withdrawal and fertility awareness-based methods.  These methods have different mechanisms of action and effectiveness in preventing unintended pregnancy.

The effectiveness of methods is measured by the number of pregnancies per 100 women using the method per year.  Methods are classified by their effectiveness as commonly used into:  Very effective (0–0.9 pregnancies per 100 women); Effective (1-9 pregnancies per 100 women); Moderately effective (10-19 pregnancies per 100 women); Less effective (20 or more pregnancies per 100 women)
