Group Intervention Description LNG IUS LNG IUS Levonorgestrel Intrauterine System (LNG IUS) (initial in vitro release 20 µg/24h) intrauterine for minimum of 9 months and maximum of 60 months - 2 phases: a) Contraception Phase b) Hormone-Replacement Therapy (HRT) Phase. For outcome measures (vaginal bleeding variables), five 90-day Reference Periods were defined, which were used for comparison during statistical analysis: Reference Period -1 in Contraception Phase; Reference Periods 1-4 in HRT Phase. 90-day reference periods for analyzing vaginal bleeding data are defined by World Health Organization (WHO) guideline. Reference Period -1 is the last 90-day reference period that the subject had before starting the HRT. Reference Period 1 covers the first 90-days of the HRT phase, Reference Period 2 covers days 91 to 180, Reference Period 3 days 181 to 270, and Reference Period 4 days 271 to 360 of the HRT phase.
- Primary Outcome Measures
Name Time Method Number of Bleeding Days Last 90 days in Contraception Phase and first 360 days in Hormone-Replacement Therapy (HRT) Phase Measured by using Subject Diaries (Subject Reported Data)
Number of Spotting Days Last 90 days in Contraception Phase and first 360 days in HRT Phase Measured by using Subject Diaries (Subject Reported Data)
Percentage of Participants With Successful Treatment Last 90 days in Contraception Phase and first 360 days in HRT Phase Definition of successful treatment:
* Completion of HRT phase, and
* Both, the number of bleeding days and the number of spotting days during HRT was equal to or less than during contraceptive phase, and
* The number of bleeding days and the number of spotting days could be calculated for at least 3 out of the first 4 reference periods in HRT
- Secondary Outcome Measures
Name Time Method Progestogenic Symptom 6: Decreased Libido (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Climacteric Symptom 1: Hot Flushes (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Climacteric Symptom 5: Irritability (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Climacteric Symptom 6: Breast Tension (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Progestogenic Symptom 7: Hair Loss (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Progestogenic Symptom 8: Greasy Hair (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Progestogenic Symptom 1: Headache (as Measured by a Visual Analogue Scale (VAS)) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Assessment of QOL as Measured by Women's Health Questionnaire Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Women's Health Questionnaire (Total Score). For the Total score, the minimum is 36 and maximum is 144. A higher score means the distress and dysfunction are less pronounced.
Continuation Rates At entry, at 2 years, at 4 years Percentage of subjects continuing in the study at the given time points.
Progestogenic Symptom 2: Depressive Mood (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
Progestogenic Symptom 3: Acne or Greasy Skin (as Measured by a VAS) Last measurement before start of HRT phase, 6 months after start of HRT phase, 12 month after start of HRT phase Higher value means the symptom is more pronounced. Minimum is 0, maximum is 100.
