Forensic Medicine · Sexual offences: emergency contraception

Sample item

A 21-year-old woman presents 4 days after an unprotected sexual assault and requests emergency contraception. Which of the following is the most effective option?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Copper intrauterine device insertion

A copper IUD inserted within 5 days is the most effective emergency contraceptive, with a failure rate under 1 percent, and it remains effective up to 5 days after unprotected intercourse. Levonorgestrel is licensed for use within 72 hours and the Yuzpe regimen is less effective and also time-limited.

Option by option

  • A. Combined pill (Yuzpe) regimen

    The Yuzpe regimen is less effective and has more side effects than other methods.

  • B. Levonorgestrel 1.5 mg single dose

    Levonorgestrel is labelled for use within 72 hours and becomes less effective as time passes.

  • C. Copper intrauterine device insertion (correct)

    The copper IUD works throughout the 5-day window and is the most effective method.

  • D. Depot medroxyprogesterone injection

    Depot medroxyprogesterone is not an emergency contraceptive.
