Abstract
A method for hormonal contraception comprising administering at least one contraceptive hormone in a plurality of linked taking periods optionally having a sequence lasting several years. Each taking period comprises at least one taking cycle. Each taking cycle comprises a duration-constant taking phase lasting several days and a taking pause lasting several days. In each taking phase the hormonal component is administrated in a daily unit. In each taking pause either a placebo or no unit is administered. The duration of the taking phase or phases of at least the final taking period is at least 22 days. The duration of each taking phase in any taking period preceding a following taking period is shorter than that in each of the taking phases in each following taking period.
