摘要

The invention pertains to a contraceptive kit comprising means for the daily administration of a contraceptive agent, characterised in that the single contraceptive agent is a steroid compound having an activity profile inherently combining progestagenic and estrogenic activity. Within a general class of known steroidal compounds, steroids have been found which possess an outstanding combined profile of biological properties for use in contraception, especially via monotherapy. These steroids are selected from the group consisting of steroids satisfying structural formula (I) and prodrugs thereof, wherein the dotted lines each independently indicate an optional bond.
