Eligibility Criteria

Male participants from 40 years up to 70 years old.

Inclusion Criteria: 1. Men aged 40 - 70 2. Willing and able to provide written informed consent 3.

Willing to complete questionnaires 5. Involved in a monogamous, heterosexual relationship for at least 3 months with both partners motivated to have or attempt sexual intercourse at least 4 times per month beginning two weeks after study treatment (subject reported) 6. Not interested or able to use oral PDE-5 inhibitor (PDE-5i) drug therapy, and willing to forgo these treatments for the first 6-month period following study treatment (in addition may include a minimum 4-week washout since last PDE-5i use prior to completion of the baseline erectile function assessments and study treatment) 7. Willing to limit alcohol intake and eliminate use of recreational drugs for sexual encounters 8. Willing to undergo a minor surgical procedure and injection 9. Abdominal area amenable to liposuction of at least 60-120 cc of adipose tissue based on Investigator examination 10. Mentally competent and able to understand all study requirements (based on investigator assessment) 11. Willing to be available for all baseline, treatment and follow-up examinations required by protocol 12. Willing to forego participation in any other study throughout the duration of this study unless receiving prior approval by Sponsor. Exclusion Criteria: 1. Evidence of prostate cancer which requires additional radiotherapy or other adjuvant therapy 2. Previous pelvic or abdominal radiation therapy 3. Previous, concomitant or scheduled use of anti-androgen therapy 4. Untreated hypogonadism or low serum total testosterone (< 200 ng/dL) 5. Clinically evident penile anatomical deformities (e.g., Peyronie's disease) or history of priapism 6. Skin irritation, infection, wound, sore or disruption in the immediate areas of skin entry for abdominal liposuction or penile injection (including abdominal trauma and abdominal skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma)) 7. Use of any non-study treatment for erectile dysfunction within 4 weeks of study treatment and a lack of willingness to continue through 6 months after study treatment 8. Any previous penile implant or penile vascular surgery 9. Current or previous malignancy other than localized prostate cancer or nonabdominal, non-melanoma skin cancer (successfully treated or treatable by curative excision or other local curative therapy- abdominal skin cancer is exclusionary as indicated in criteria 6) 10. Uncontrolled hypertension or hypotension (systolic blood pressure > 170 or < 90 mm Hg, and diastolic blood pressure > 100 or < 50 mm Hg) 11. Reported unstable cardiovascular disease (e.g., unstable angina, myocardial infarction within past 6 months, cardiac failure or life-threatening arrhythmia, congestive heart failure) or symptomatic postural hypotension within 6 months before screening 12. Hemoglobin A1c > 8% within 8 weeks prior to study treatment 13. Current urinary tract or bladder infection 14. Drug, alcohol, or substance abuse reported within the last three years (subject reported) 15. 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) 16. Weight less than 154 lbs/ 70 kg, or BMI ≥ 30 17. Unable to limit or avoid nonsteroidal anti-inflammatory drugs(NSAIDs) for 15 days prior to treatment (subject reported) 18.
