[Changes in heparinocytes during the administration of Depositon and Sequenz-Ovosiston].

During hormonal contraception with Deposiston (once a week pill) and with Sequenz-Ovosiston (14 days mestranol 0.1 mg, 7 days mestranol 0,08 mg and 2 mg chlormadinone acetate) doesn't take place a change of basophil granulocytes (heparinocytes) in blood. Under Deposiston the small elevation is somewhat lengthened, under Sequenz-Ovosiston the elevated phase is similar to those of the normal menstrual cycle. The smaller risk of thromboembolia under heparinocytopenia preventing contraceptives is discussed.
