[Mifepristone: from pre- to post-protection].

All current hormonal contraceptives have side effects and contraindications related to estrogens and progestins. Users are often dissatisfied with this. There is a great need for a new contraceptive drug without these hormones with the associated side effects and contraindications; with also a favorable bleeding profile; that can be used orally and not daily; that can serve as a contraceptive and after-care and can also be used on demand.
