The Fertility Awareness Method (FAM) was originally established as a scientific and medically-based method of natural birth control that relied on signs from a woman's body to indicate when she was fertile. It is not, and never has been, the "rhythm" or "calendar rhythm" method. All birth control methods are evaluated based upon their use- and method-effectiveness. Method-effectiveness assumes "perfect use" and isn't quoted here because it only serves to confuse. For comparison’s sake, the birth control pill has a use effectiveness of 97%. FAM, on the other hand, has a use-effectiveness of up to 90%, which is about the same as that of the male condom. What this 90% use-effectiveness figure means is that 1 out of 10 women who use FAM as their only method of birth control will experience an unintended pregnancy during the course of a year. If you were to use it as your only form of birth control for 10 years, you could expect one unintended pregnancy. Because FAM can accurately estimate times of highest fertility, increasing numbers of couples seeking pregnancy have also used it. FAM is also the basis for Ovusoft Fertility Software -- Ovusoft automates the method and does the analysis of your fertility signs for you, identifying when you are fertile and infertile, when you have ovulated, when you might be pregnant. It also makes projections of future fertility using your own unique cycle history, so that you may plan your pregnancy. Next: How FAM Works
