Choosing a method of birth control is a highly personal decision, based on individual preferences, medical history, lifestyle, and other factors. Each method carries with it a number of risks and benefits of which the user should be aware.
Each method of birth control has a failure rate--an inability to prevent pregnancy over a 1-year period. Sometimes the failure rate is due to the method and sometimes it is due to human error, such as incorrect use or not using it at all. Each method has possible side effects, some minor and some serious. Some methods require lifestyle modifications, such as remembering to use the method with each and every sexual intercourse. Some cannot be used by individuals with certain medical problems.
