Hi, Thanks for using HCM. Erectile dysfunction may be due to many causes like vascular, neuronal, muscular and psycological cause. If you are smooker then quit smoking. Get investigated with blood glucose fasting, lipid profile, thyroid profile and testosterone level with one USG abdomen and pelvis to diagnose if any physical problem. Organize your life like eat more fruits and vegetables, do regular exercises, reduce mastrubatin if doing and avoid viewing any porn movies. Wear loose clothes and no underwears during sleep. Consult your doctor for examination and management. Hope I answered your question. Feel free to ask me if you have any further queries. Come back to me if any abnormality in the above said investigations. Wish you good health. Take care. Regards Dr. Lohit
