Study acronymDE-NOVO
Study objectives
Ethics approval(s)

Approved 29/10/2026, L'Ombudsman Uke (via delle olimpiadi 4, Enna, 94100, Italy; +39 935/536536; protocollo@unikore.it), ref: 32375

Health condition(s) or problem(s) studiedVascular erectile dysfunction
InterventionActive Arm: Patients receive 40 sessions of Hyperbaric Oxygen Therapy (HBOT) at 2.5 atmospheres absolute (ATA). Each session lasts 90 minutes and treatments are performed 5 days a week until the 40-session cycle is completed.
Control/Placebo Arm: Patients receive a sham treatment consisting of 40 sessions in the hyperbaric chamber at 1.1 ATA to ensure blinding. Each session lasts 90 minutes, 5 days a week.
Follow-up: Clinical evaluations (using the IIEF-5 questionnaire) and penile Doppler ultrasound (to measure Peak Systolic Velocity) are performed at baseline, and subsequently at 3, 6, and 12 months for all study arms.
Randomisation: Patients were randomly assigned to the two treatment arms in a 2:1 ratio (treatment vs. control).
Intervention typeProcedure/Surgery

  1. Penile vascular function and response to iPDE5 measured using IIEF5 and penile vascular doppler at 0, 3, 6 and 12 months
