Primary Outcome Measures:
  • The primary endpoints are the increases in how often women have satisfying sexual events and in how much their sexual desire increases. Both are measured by making daily entries in an electronic diary. [ Time Frame: 28 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Changes from baseline on diary sexual distress question and on a small number of patient-completed questions/questionnaires. [ Time Frame: 28 weeks ] [ Designated as safety issue: Yes ]
