title: Emergency contraception in a country with restricted access to contraceptives and termination of pregnancy, a prospective follow-up study.
abstract: OBJECTIVE
  Poland has a restrictive abortion law. Emergency contraception (EC) is expensive and available only on prescription, which is not easily obtainable in public health care. We aimed to identify the main reasons for EC requests, observed failure rates and the type and incidence of adverse effects.
  
  
  METHODS
  Prospective single-center observational study.
  
  
  METHODS
  A cohort of women living in Warsaw, who requested EC.
  
  
  METHODS
  Data were collected via a questionnaire completed by healthcare providers prescribing EC, and included age, date of the request, previous EC use, time from intercourse to clinic visit and day of menstrual cycle on which intercourse took place.
  
  
  METHODS
  Reason for EC request, time lapse between unprotected intercourse and EC use, age of women requesting EC, reported cases of pregnancy.
  
  
  RESULTS
  A total of 4655 women requested EC. Of these 62.9% (n = 2928) were ≤25 years old. During follow up, 0.75% (31 individuals) became pregnant. Adverse effects of hormonal EC were rare and mild. The main reason for requesting EC was problems associated with condoms (63.2%, n = 2609). The mean interval between unprotected intercourse and EC use was 21.2 h, but 26.7 h when EC failed (n.s.). Considering intake within and after 24 h, the difference was significant (p < 0.05).
  
  
  CONCLUSIONS
  Women living in Warsaw seeking EC used the EC product very soon after unprotected intercourse, and this was probably one of the most important reasons for the low pregnancy rates in the studied population.
