In an effort to identify the main reasons for EC requests, observed failure rates, and the type and incidence of adverse effects among EC users in Poland, a prospective single-center observational study was conducted among 4655 women living in Warsaw. Data was collected via a questionnaire completed by healthcare providers prescribing EC and focused on the following outcomes: reason for EC request, time lapse between unprotected intercourse and EC use, age of women requesting EC, and reported cases of pregnancy. The study found that of the women requesting EC, 62.9% were ≤ 25 years old and 0.75% became pregnant; adverse effects were rare and mild; and the main reason for requesting EC was problems associated with condoms. Additionally, the mean interval between unprotected intercourse and EC use was 21.2 hours, although it was 26.7 hours when EC failed. The researchers concluded that women living in Warsaw seeking EC used it very soon after unprotected intercourse, and this was probably one of the most important reasons for the low pregnancy rates observed in the study population.
