Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Natesto
Natesto™ is a testosterone nasal gel that is FDA approved to treat low testosterone.
It delivers testosterone through the nasal passages and it is then absorbed into the blood stream.
The nasal pump is placed at the opening of each nostril and then the participant would press down on the nasal pump to apply the gel.
Each application takes about 10 seconds and the nasal pump applies a thin layer of gel that absorbs through the lining of the nose.
|
Nasal Gel used for 90 days then crossed over to placebo gel
Other Names:

Placebo Comparator: Placebo
This study involves a placebo.
The placebo will look like the Natesto™ nasal pump and will contain a nasal gel, but without any active ingredients.
|
A nasal gel with no active ingredients

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparison of Erectile Function and Sexual Intercourse Satisfaction Total Scores Recorded at Baseline and End of Study.
Time Frame: At Baseline and at the end of the study (Day 180)
|
The primary endpoint of the study will be mean change in erectile function and satisfaction with sexual intercourse using the validated SHIM questionnaire. This questionnaire has been used extensively in clinical trials evaluating PDE5i for ED and is also used very commonly in the clinical practice. The SHIM Is a 5 item questionnaire that assesses the ability to get and maintain an erection sufficient for intercourse (Q1-Q4) and Q5 which assesses patient satisfaction. Each question is scored 0 to 5 with a total maximum score of 25. The investigators will look at the answers to all 5 questions and a higher score is interpreted as a better outcome. |
