Each cycle (28 days), daily intake of:
1. Microgynon® (150 µg levonorgestrel [LNG]/30 µg ethinyl estradiol [EE]) or Yasmin® (3 mg drospirenone [DRSP]/30 µg EE); on day 1 - 21 2. 50 mg DHEA or placebo in two tablets; on day 1 - 28 Pretest period: 1 cycle (no OC) Treatment period 1: 5 cycles Treatment period 2: 5 cycles Total treatment duration: 10 cycles (each cycle: 28 days) |

2. Sexual function as assessed with the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R), at screening, pretest, study visit at end of each treatment period 3. Vaginal pulse amplitude (VPA) during sexual stimulation and experience of sexual arousal during sexual stimulation, at pretest visit, study visit at end of each treatment period |
| Secondary outcome measure(s) |
1. Androgen parameters, measured at screening, pretest visit, study visit at end of each treatment period
2. Daily hassles, completed during the last two treatment cycles of each treatment period 3. Health diary, completed during the last two treatment cycles of each treatment period 4. Haemostasis metabolism, measured at screening, pretest visit, study visit at end of each treatment period 5. Bleeding data, measured with diary keeping during both treatment periods 6. Safety assessment, measured throughout the study |
