Erectile function severity at baseline and after hyperbaric oxygen therapy (HBOT). After HBOT, 63% of the men had none to mild erectile dysfunction. Erectile function is calculated as the total of questions 1, 2, 3, 4, 5, and 15. Erectile dysfunction severity is graded as: 0–6 severe dysfunction, 7–12 moderate dysfunction, 13–18 mild to moderate dysfunction, 19–24 mild dysfunction, 25–30 normal function
