Brief summary
The purpose of this study is to look into the effectiveness of a new investigational medication applied as a transdermal patch. The patch is applied on the skin with study medication that is absorbed through the skin suppressing ovarian activity and therefore preventing an egg from leaving an ovary (ovulation). The study will look into the study drug's safety and how well it is tolerated and its absorption, breakdown and elimination in the body. It describes how the body affects a specific drug after administration.
Interventions
7 day patch containing 0.55 mg ethinyl estradiol and 2.1 gestodene in a 21 day regimen.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Suppression of ovulatory activity proved by progesterone and estradiol concentrations | Treatment day 29 to day 84 | Estradiol levels \> 100pmol/L indicate some ovarian activity and progesterone levels \> 5nmol/L in subjects with estradiol levels \> 100pmol/L reflect ovulation or luteinized unruptured follicles. |
