Brief Summary

This is an open-label, multi-centre, comparative study in young, healthy, female volunteers of reproductive age. Primary objective: \- To investigate the effect of 2 dosages of estetrol combined with P1 or P2, on vaginal bleeding patterns (cycle control), in comparison with a combined oral contraceptive containing estradiol valerate and dienogest Secondary objectives:

  • To investigate ovulation inhibition
  • To investigate the effect on SHBG
  • To assess pregnancy rate
  • To evaluate subject satisfaction, dysmenorrhoea, acne, and body weight
  • To investigate return of menstruation after treatment
  • To evaluate general safety and acceptability
