EndoPAT Device for Endothelial Dysfunction in ED

This study is looking at how two different treatments affect blood vessel health in men with erectile dysfunction (ED) or low testosterone (hypogonadism). Researchers will use a special device called EndoPAT to measure your endothelial function (how well your blood vessels work) at the beginning of the study, and then again at 3 and 6 months after treatment. One group will receive daily low-dose PDE5 inhibitor therapy, and another group will receive testosterone therapy. The study aims to see if these treatments improve blood vessel health. This study is currently unclear in its recruitment status and plans to enroll 120 men.

Study design
This interventional study plans to enroll 120 men. There are two treatment groups, but they are not directly compared to each other.
What's involved
You would have your endothelial function measured using the EndoPAT device at the start of the study, and then again at 3 months and 6 months after starting your assigned treatment.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 6 months after starting their intervention to measure endothelial function.

Eligibility criteria

Inclusion

Males 18 years old and above
Diagnosed with erectile dysfunction or hypogonadism

Exclusion

Patients without the above criteria
  • Endothelial Function as Measured by Reactive Hyperemia Index (RHI)At baseline, 3 months, and 6 months post-intervention

    Definition: RHI is a measure of endothelial function derived from the EndoPAT device, which assesses the endothelium's ability to respond to induced hyperemia. Measurement: RHI is calculated based on the changes in digital pulse volume during reactive hyperemia following a 5-minute arterial occlusion. Criteria for Evaluation: Baseline RHI: Measured before any intervention. Post-Intervention RHI: Measured at 3 months and 6 months post-intervention. Improvement in RHI: Defined as an increase in RHI scores from baseline to follow-up measurements.
