Brief summary
The primary objective of this trial is to examine whether ovulation is suppressed after use of hormone patches containing different dosages of ethinyl estradiol (EE) and gestodene (GSD) for 3 treatment cycles. To this end, the blood levels of endogenous hormones (hormones produced by your body) will be measured and transvaginal ultrasound examinations will be conducted at regular intervals. In addition, the concentrations of the administered hormones EE and GSD in blood will be determined in regular intervals. With regard to the tolerability of the hormone patches subjects will be asked regularly how they feel and blood pressure, pulse and body weight will be determined. In addition, blood and urine safety examinations will be conducted at defined timepoints.
Interventions
0.55 mg ethinyl estradiol (EE) + 2.1 mg gestodene (GSD) per patch; 3 treatment cycles; 21 days per treatment cycle, i.e. 3 x 7 days patch-wearing phase and a patch-free interval of 7 days
