L-Arginine and Tadalafil for Erectile Dysfunction

This study is investigating the effectiveness and safety of different treatments for men experiencing erectile dysfunction (ED). ED is a condition where a man has trouble getting or keeping an erection suitable for sexual intercourse. The study focuses on men who have not been previously treated for mild to moderate ED. Participants are divided into three groups to compare how well L-arginine alone, Tadalafil alone, or a combination of both can help improve their condition. L-arginine is a natural substance that helps produce nitric oxide, which is important for erections, while Tadalafil is a widely used medication for ED. Understanding which treatment works best could improve treatment options for men with ED. Participants in the study will take their assigned treatment daily for eight weeks. Group 1 will take L-arginine, Group 2 will take Tadalafil, and Group 3 will take both L-arginine and Tadalafil. Before starting the treatment and after eight weeks, participants will have a series of assessments including medical history, physical exams, and laboratory tests like testosterone levels. They will also undergo a penile ultrasound to check tissue stiffness. Throughout the study, participants will be monitored for any side effects and changes in their ED condition using a questionnaire. The goal is to determine which treatment offers the best improvement in symptoms with the least side effects.
