    Area of Science:

    • Reproductive Health
    • Family Planning
    • Medical History

    Background:

    • The rhythm method is a natural family planning (NFP) technique.
    • It is the only contraceptive method endorsed by the Roman Catholic Church, attracting many adherents.
    • Historical development traces back to the 19th century, with contributions from Ogino and Knaus.

    Purpose of the Study:

    • To review the historical evolution of the rhythm method.
    • To examine variations including basal body temperature and cervical mucus methods.
    • To assess reported risks and use-effectiveness of the rhythm method.

    Main Methods:

    • Historical literature review of the rhythm method's development.
    • Analysis of variations based on physiological indicators (BBT, cervical mucus).

  • Examination of field trial data on use-effectiveness and reported risks.

    • Main Results:

    • The rhythm method has evolved significantly since the 19th century.
    • Variations incorporate basal body temperature and cervical mucus monitoring.
    • Reported risks include fertilization of overripe ova and increased ectopic pregnancy rates.

    Conclusions:

    • The rhythm method, despite its Church approval, presents potential risks.
    • Ectopic pregnancy risk may be higher compared to other contraceptive methods.
    • Further examination of use-effectiveness in field trials is crucial.
