OBG · Gynaecological oncology: hydatidiform follow-up contraception

Sample item

Which contraceptive method is preferred while monitoring hCG after a molar pregnancy until levels normalise?

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

The answer and the reasoning

D. Barrier method or combined oral contraceptive pill

Reliable contraception avoids confusion between a new pregnancy and persistent trophoblastic disease, and COCs do not increase the risk of GTN. An IUCD is avoided until hCG is normal because of the risk of uterine perforation if invasive mole is present. Rhythm and withdrawal methods are unreliable.

Option by option

  • A. Intrauterine device

    An IUCD is avoided until hCG is normal.

  • B. Rhythm method

    The rhythm method is unreliable.

  • C. Withdrawal

    Withdrawal is unreliable.

  • D. Barrier method or combined oral contraceptive pill (correct)

    Correct. Reliable non-intrauterine methods are preferred.
