• Any previous penile implant or penile vascular surgery
• Current or previous malignancy other than localized prostate cancer or non-abdominal, non-melanoma skin cancer (successfully treated or treatable by curative excision or other local curative therapy- abdominal skin cancer is exclusionary)

• Subject's sexual partner is < 18 years of age, nursing, or known to be pregnant at screening, or wishes to become pregnant during the study period, or has any gynecologic problems, major medical conditions, or other factors that would limit participation in sexual intercourse to less than 4 times per month (subject reported)
