    Area of Science:

    • Reproductive Health
    • Pharmacology

    Background:

    • Postcoital contraception has evolved from emergency measures to ongoing methods.
    • Hormonal steroids and intrauterine devices (IUDs) are key developments.

    Purpose of the Study:

    • To review the evolution and current status of postcoital contraception.
    • To highlight the role of emergency postcoital contraception.

    Main Methods:

    • Review of hormonal steroids (estrogens, progestins) and copper-bearing IUDs.
    • Analysis of failure rates based on dosage, progestin type, and intercourse frequency.

    Main Results:

    • Estrogens, often in combination with progestins, are common emergency measures.
    • Copper-bearing IUDs are effective when inserted within seven days.

  • Progestins are used for ongoing postcoital contraception with variable failure rates.

    • Conclusions:

    • Postcoital contraception's primary role in developed countries is emergency use.
    • High efficacy, availability, and low side effects are vital for acceptance.
