title: Criteria for appropriate birth control.
abstract: Women seeking protection from pregnancy require adequate information about the relative merits and risks of current contraceptive options in order to make an informed choice. A basic understanding of mechanisms of action, the projected rates of efficacy, the demands on compliance, and the risks of side-effects permits women to weigh options appropriately and attain confidence in their chosen method. An informed woman is also in a better position to switch to alternative methods in the event of dissatisfaction or changing needs. Within the category of highly effective methods of birth control, to which a monthly combination injectable contraceptive has recently been added in several countries, there are important distinctions in relative reversibility, effect on menstrual cycle and confidentiality.
