In the Atlantic, The New Old-School Birth Control
There is a good amount of research and educational programs devoted to natural fertility awareness-based methods of birth control (FABM), though they may not yet be well-known.Posted by Jill Fallon at October 14, 2013 9:19 AM | Permalink
Surveys conducted by physicians at the University of Utah show that when natural fertility-awareness methods are described to women, 25 percent say they would strongly consider using one as their means of birth control. But thanks to its glaring image problem and a set of just-as-formidable infrastructural hindrances, ignorance of fertility awareness-based methods is widespread. If more women looking for a non-hormonal, non-barrier, non-surgical form of birth control knew about FABM, then more of them could be practicing it to its utmost effectiveness—rather than doing it in the dark.
A recent 20-year German study asked 900 women to track their fertility every day by monitoring their body temperature and cervical mucus, and use that information to avoid pregnancy. The study’s researchers found this to be 98.2 percent effective—comparable with the pill, and a far cry from the 82 percent effectiveness rate of the withdrawal method.
In January, a group of physicians organized through the Family Medicine Education Consortium published a review looking into the efficacy of various FABMs. They combed through all the relevant research published since 1980, and concluded that “when correctly used to avoid pregnancy, modern fertility awareness-based methods have unintended pregnancy rates of less than five (per 100 women years).” (A woman year is one year in the reproductive life of a woman.) Their effectiveness levels, in other words, are “comparable to those of commonly used contraceptives,” the study’s authors add.
