[Extrauterine pregnancy after hormonal postcoital contraception]

Postcoital contraception with estrogen-gestagen-combinations is a highly effective emergency measure in cases of unprotected sexual intercourse at midcycle. Pregnancies after hormonal postcoital contraception are rare and ectopic pregnancies are said to be an extreme rarity. At the Department of Obstetrics and Gynecology of the Philipps-University Marburg we could observe two women with ectopic pregnancies after administration of a ethinyestradiol-levonorgestrel combination (Tetragynon, Schering, Berlin). Both patients were operated by pelviscopy. We could not found a clear causal relationship between the administration of hormonal postcoital contraception and ectopic pregnancies, because both women had intrauterine operations in her history and therefore a certain level of tubal damage could not ruled out. Nevertheless, in cases of hormonal postcoital contraception a follow-up check after 3 weeks should be done and it should be kept in mind that ectopic pregnancies may occur, especially in patients with risk factors.
