             during the past 6 months and according to the Diagnostic and Statistical Manual of
             Mental Disorders IV (DSM-IV) criteria. Subtype should be generalized and not due to
             etiological factors that would be unlikely to be related to hormone function (eg,
             depression, relationship discord, alcoholism, surgery, injury). Hypoactive sexual
             desire disorder as a co-morbid disorder is allowed only if it began after the female
             orgasmic disorder diagnosis;

          -  Have a score of >15 with a score of ≥2 for question #15 on the FSDS DAO at Screening
             Visit;

          -  Be a sexually active, hetero- or homosexual woman in a steady relationship for at
             least 6 months and agree to have at least 4 sexual events over 28-day period of time.
             The subject's partner should not have any untreated sexual dysfunctions;

          -  Be on a reliable birth control method (ie, stable systemic hormonal contraception for
             the whole duration of the study and 30 days after study completion [for at least 3
             months prior to study], IUD, barrier method) or not engaging in heterosexual
             intercourse. Birth control method used by subject at screening is not to be changed
             during the course of the study;

          -  Have a body mass index ≤35;

             laboratory facility (no evidence of malignancy) within the 2 years prior to
             Randomization;

          -  Have a clinically acceptable mammogram;

          -  Be able to complete a web-based questionnaire within 24 hours of each sexual event;

          -  Be able to read English and provide written informed consent; and

        At Visit 2:

             drug;

          -  Have a history of any clinically relevant psychiatric disorder that could impact

             severe anxiety, eating disorders, borderline personality disorder, untreated Major
