Emergency contraception, including the Yuzpe regimen and IUDs, has been available for decades. Family planning programs should offer these vital services to prevent unwanted pregnancies and reduce unsafe abortions.

Area of Science:

  • Reproductive Health
  • Contraception Research
  • Medical History

Background:

  • Emergency contraception (EC) refers to methods preventing pregnancy after unprotected intercourse.
  • Historical use of postcoital preparations dates back to ancient Egypt.
  • Modern EC development began in the 1960s with hormonal therapies.

Purpose of the Study:

  • To review the historical development and current status of emergency contraception.
  • To emphasize the importance of EC in preventing unwanted pregnancies and associated maternal mortality.
  • To advocate for the integration of EC into routine family planning services.

Main Methods:

  • Review of historical contraceptive research and clinical trials.
  • Examination of hormonal methods (oestrogens, progestogens, levonorgestrel, mifepristone, danazol).

  • Inclusion of non-hormonal methods like the intrauterine contraceptive device (IUD).

    • Main Results:

    • The Yuzpe regimen (combined oestrogen-progestogen) emerged in the 1970s.
    • Intrauterine contraceptive device (IUD) insertion for EC was reported in 1976.
    • Established EC methods have been available for approximately 30 years.

    Conclusions:

    • Emergency contraception plays a crucial role in preventing unwanted pregnancies and reducing morbidity/mortality from unsafe abortions.
    • Given the long availability of effective EC methods, family planning programs must offer these services.
    • Failure to provide EC services hinders efforts to improve women's reproductive health.
