because there is no profit motive to spend advertising dollars on their behalf. Very few physicians are well informed about Fertility Awareness Based Methods (FABMs) of family planning, but in the interests of informed consent, should become aware of these alternatives to offer their patients.
One reason for physicians’ lack of interest in FABMs is that the data shown on the CDC web site shows a high failure rate for these methods. (1) The data they cite, however, is old and comes from flawed studies. More recent, controlled and large scale studies show very low failure rates for these methods.(2) The American Academy of Family Physicians contacted the CDC in April of 2016 to request an update of the data, but received no response. A petition has been organized to ask the CDC to update the data, hoping that a large number of signatures will get their attention and spur some action.
