Abstract

PIP: NFP (natural family planning) has replaced the term of rhythm method in the last decade as a designation for those methods of fertility regulation based on periodic abstinence. A graph presents the symptoms observable during the menstrual cycle and the ways in which these symptoms coincide with the fertile and infertile periods within the cycle. NFP counseling aims at teaching couples how to recognize the beginning and end of the fertile period within the menstrual cycle. Each of the following types of NFP are discussed and explained in detail: 1) calendar or calculation method; 2) temperature method; 3) symptothermal methods; and 4) cervical mucus methods. All of these involve detection of the time of ovulation combined with abstinence during the fertile period of the cycle. The symptoms to recognize are taught with each method. Findings from 5 retrospective and 12 prospective studies on the effectiveness of NFP are tabulated. Current research and suggested areas for future research in the field of NFP are mentioned. In the last 20 years, NFP has been popularized through more popular-oriented educational programs. Governments have taken over funding of some NFP programs. Now that NFP effectiveness has been well established, motivation and counseling will be the most important elements in NFP education in the future.
