SECONDARY outcome

Timeframe: Baseline

Assessment of the Sexual Health Inventory for men (SHIM) questionnaire before treatment for both groups. It is a questionnaire that helps asses if the patient has erectile dysfunction (ED) and assesses its degree. Results range from 1 to 25. A score of 1-7 denotes Severe ED, 8-11 Moderate ED, 12-16, Mild to Moderate ED, 17-21 Mild ED, 22-25 No ED.
