OBG · Contraception

Sample item

A woman presents three days after unprotected intercourse and wants the most effective method of emergency contraception. Which should be offered?

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

The answer and the reasoning

C. Copper intrauterine device

A copper IUD inserted within five days of unprotected intercourse is the most effective emergency method and also provides ongoing contraception. Hormonal pills delay ovulation, and their efficacy falls with time since intercourse.

Option by option

  • A. Levonorgestrel pill

    Levonorgestrel is effective if taken early, but less so than the copper device.

  • B. Combined oestrogen-progestogen pills

    The combined regimen has more side effects such as nausea and is less effective than the other options.

  • C. Copper intrauterine device (correct)

    Correct. It is the most effective emergency method and can be left in for ongoing contraception.

  • D. Oral progestogen-only minipill

    Routine minipills are not an emergency method and do not give reliable protection.
