Acceptable forms of birth control include the use of an IUD or hormonal therapy (oral, patch, etc.).

You may not qualify if…

• Participant is nursing or pregnant (based on positive serum pregnancy test), or wishes to become pregnant during the study period.
• Participant has any disorder or a history of any disorder that may prevent the successful completion of the study in the opinion of the Sub-Investigator.
• Participant has used any topical hormone replacement therapy (HRT) applied locally to the genitals in the past three months. Oral and patch form of HRT are acceptable, as long as the participant reports being on a stable dose for at least 6 months prior to Visit 1.
• Participant has a significant cardiovascular, hepatic, metabolic, renal, respiratory, gastrointestinal, endocrine, immunologic, dermatologic, hematologic, neurologic, genitourinary, or psychiatric disease or other unstable medical condition that would contraindicate administration of study medication, interfere with study evaluation, limit study participation, or confound the interpretation of study results in the opinion of the Sub-Investigator.
• Participant had an active ulcer or clinically significant bleeding disorder.
• Participant has a history of myocardial infarction, stroke, or life-threatening arrhythmia within 6 months prior to Visit 1; or any history of coronary disease causing angina; or congestive heart failure requiring medical intervention.
• Participant has retinitis pigmentosa or sickle cell anemia or related anemias, even if the participant feels clinically well at the time of Visit 1. Participants with retinitis pigmentosa will be identified by specifically asking whether they have the condition, if there are visual signs and symptoms of the condition (including questioning participants as to whether they have difficulty seeing at night or in low light, and if they have any visual field deficits that indicate a loss of peripheral or central vision), or if there is a family history.
• 8 Participant has a history of orthostatic hypotension or orthostatic hypotension which is present at Visit 1, defined as a drop in systolic blood pressure ≥ 20 mm Hg, a drop in diastolic blood pressure ≥ 10 mm Hg or experiencing lightheadedness or dizziness at 1 or 3 minutes after the change in position from supine to standing.
• Participant has primary anorgasmia, vaginismus, or sexual aversion disorder.
• Participant has dyspareunia.
• Participant has type 1 or type 2 diabetes.
• Participant has undergone major pelvic surgery that may have caused nerve damage, including, vulvectomy, colostomy, cystostomy, or serious bladder, rectal, or abdominal surgery; neurological impairment due to diabetes, stroke, pelvic nerve damage secondary to trauma, cancer treatments, myasthenia gravis, multiple sclerosis or spinal cord damage.
• Participant has current and/or previous reported diagnoses of DSM-IV-TR axis I disorders including organic mental syndromes and disorders (e.g., schizophrenia, bipolar disorder, depression).
• Participant has a history of cancer, other than basal cell carcinoma.
• Participant has any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the test article in the opinion of the Sub-Investigator.
• Participant has a history of non-arteritic ischemic optic neuropathy (NAION).
• Participant has positive findings from the urine drug screen (e.g., amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, methadone, and opiates).
• Participant has positive serologic findings for sexually transmitted infection (syphilis, gonorrhea, chlamydia), human immunodeficiency virus (HIV) antibodies, hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibodies.
• Participant has moderate to severe current vaginitis, a vaginal infection including bacterial vaginosis or a yeast infection. The diagnosis of yeast infections should be made by the Sub-Investigator based on the physical and gynecological exams; the objective is to exclude women that are symptomatic. If the woman is not complaining of symptoms but the Sub-Investigator observes discharge, than the vaginal wet mount test should also be performed to confirm a diagnosis of yeast infection.
