ED can be primary or secondary:
Primary ED: It is present from the first experience of sexual intercourse Secondary ED: When an individual develops ED after a period of normal penile function

Causes of erectile dysfunction
There are multiple causes of ED, ranging from psychological to external causes such as medications. Some of the common causes include:
Psychogenic causes such as depression and anxiety disorders
Anxiety Depression Fatigue Guilt Stress Marital discord Excessive alcohol consumption
Diseases associated with blood vessels that may present as ED:
Atherosclerosis Hypertension
Trauma: Injuries around the penis can also contribute to ED.Medical conditions that may contribute to ED:
Neurological disorders that may contribute to ED: Nerves to the penis can be damaged due to conditions such as a stroke or diabetes
Medications that may contribute to ED:
Certain prescription drugs such as diuretics (to decrease blood pressure by decreasing urine flow), antihypertensives (to reduce high blood pressure), antidepressants, or antihistamines may cause ED Use of recreational drugs affect CNS, damage the arteries, and may lead to permanent ED
Clinical Features ED is characterised by the following features:Â

Other sexual disorders that can be associated with ED include:

Diagnosis ED is diagnosed through medical and sexual history taking as well as mental and physical examinations which includes a physician asking about the frequency, quality, and duration of erections.Â
Some diagnostic tests for ED include:Â
Nocturnal penile tumescence testing: This measures the patient’s erection during sleep. Involuntarily erections occur four to five times during sleep and normal sleep erections in ED suggest emotional problems. However, if the patient does not experience erections while sleeping, the cause of ED might be more physical in nature Doppler ultrasonography: This is done to observe the blood flow around the penis to identify any obstructions in the arteries supplying it Routine blood test: A blood test is done to rule out medical conditions that may lead to ED such as diabetes, heart or kidney disease Psychiatric consultation: A psychiatric consultation can be done to assess mental or emotional issues such as depression or anxiety
Differential Diagnosis
Other medication conditions that may have similar symptoms to ED include:Â
Andropause: This is a condition where a decrease in the male sex hormone testosterone may result in a lowered sex drive or difficulties getting erections Diabetes : This can affect the blood vessels that allow for penile erection and its maintenance Heart disease: The formation of plaque inside the arteries may hinder blood flow to different parts of the body parts including the penis Kidney disease: This can affect hormone levels, blood flow, and the nervous system, which are all required to maintain a healthy erection Neurological problems: Parkinson’s, Alzheimer’s and multiple sclerosis can lead to ED.

Surgery
An inflatable implant, can be placed surgically in the penis to make it longer and wider Malleable implants such as rods allow manual adjustments to the position of the penis Blood vessel reconstruction where the artery of the penis is surgically repaired to reverse any obstruction of blood flowing to the penis
