title: [The first three-stage preparation for hormonal contraception. Clinical results (author's transl)].
abstract: The controlled clinical trial is reported of a new three-stage oral contraceptive which has meanwhile been introduced on to the market under the trade name Triquilar. Triquilar has a reliable contraceptive action: no pregnancy occurred in 8068 treatment cycles. In spite of the very low doses of estrogen and gestagen--Triquilar contains the lowest total quantity of steroids of all available preparations--the multistage structure guarantees an outstanding cycle control and a particularly good general tolerance. The reasons are discussed which today support the use of an oral contraceptive with the lowest possible amounts of the two hormone components.
