Summary

This 4-year study verified the effectiveness of the basal body temperature (BBT) and symptothermal methods for natural family planning (NFP). Results show a Pearl Index of 3.6 for unplanned pregnancies when using NFP for spacing.

Area of Science:

  • Reproductive Health
  • Family Planning Methods
  • Clinical Effectiveness Studies

Background:

  • Natural Family Planning (NFP) methods, including basal body temperature (BBT) and symptothermal approaches, require rigorous verification for effectiveness and applicability.
  • Understanding the motivational factors influencing adherence to NFP is crucial for successful implementation.

Purpose of the Study:

  • To verify the effectiveness and applicability of BBT and symptothermal methods over a 4-year period.
  • To assess the impact of psychological motivation and anthropological, relational, pedagogical, and moral factors on NFP use.
  • To determine the Pearl Index for unplanned pregnancies in couples utilizing NFP.

Main Methods:

  • A 4-year observational study involving 460 couples trained in NFP.
  • Couples underwent a 6-month study phase with emphasis on motivational factors.
  • Data collection included charting of BBT, cervical mucus, and intercourse over 8,140 cycles.

Main Results:

  • The study recorded a Pearl Index of 3.6 for unplanned pregnancies among couples using NFP for spacing.
  • Twenty-five unplanned pregnancies occurred in the NFP spacing group.
  • No pregnancies were reported in couples using NFP as limiters.

Conclusions:

  • BBT and symptothermal methods demonstrate a measurable effectiveness in natural family planning when couples are well-trained and motivated.
  • The study provides empirical data on the Pearl Index for NFP, highlighting its efficacy for both spacing and limiting pregnancies.
  • Motivational factors play a significant role in the successful application of NFP methods.
