Progestogen-antiprogestogen regimens

摘要

An estrogen-free contraceptive is disclosed which does not have the bleeding-related drawbacks of conventional progestogen-only pills. The invention includes a contraceptive kit comprising a combined means for the simultaneous daily administration of a progestogen and an anti-progestogen. The combined means may be in the form of tablets having a normal contraceptive dose of the progestogen and a low dose of the anti-progestogen.
