Natural family planning methods

Wade et al.'s report, entitled "A randomized prospective study of the use-effectiveness of 2 methods of natural family planning," contains items worthy of emphasis. These includes the following: 1) less than 5% of the women in the study were prevented from using the method assigned them because of problems in identifying their cervical mucus pattern; 2) those who were unable or unwilling to adhere to the methodology were encouraged to drop out; 3) the largest single category of pregnancies occurred in both groups when the volunteers failed to follow the rules for avoiding pregnancy; 4) it was judged that there were 6 pregnancies in the ovulation method group to be classified as method failures, apparently for a total of 4501 cycles, which gives a method-failure rate of 1.6%; 5) couples were required to sign an informed consent statement of their awareness that the chances of the occurrence of pregnancy could be as high as 25% for the ovulation method; 6) recruiting difficulties constituted an important finding, primarily because they were unexpected by the investigators; 7) the volunteers recruited into the trial were restricted to those women whose menstrual cycles were 24-36 days; 8) the couples who failed to continue with the use of these 2 natural methods--ovulation and temperature rhythm--were on the average younger, more sexually active, and had fewer children; and 9) the ovulation method brings the partners into confrontation with their fertility in each cycle, and this has marked psychological results, including an awakening of the suppressed desire for that fertility to become creative of human life.
