title: Post-coital contraception by estrogen/progestagen combination or IUD insertion.
abstract: Five-hundred-thirty-eight patients received a complete follow-up to the first menses after post-coital contraception (PCC). Hormonal contraception (pill) was used in 436 women and mechanical contraception (IUD) was used in 102 women. No pregnancies were observed in the IUD group, while 8 pregnancies were found in the hormonal group. A comparative evaluation of the effectiveness and side effects of the two methods was made. The usefulness of PCC after an unprotected intercourse in order to avoid a pregnancy is confirmed.
