Erectile dysfunction (ED) is the inability to get or keep a firm erection sufficient for sexual intercourse.
In an erection, impulses from the brain and local nerves cause the muscles of the corpora cavernosa, two chambers in the penis, to relax and allow blood to flow in through the arteries and fill the spaces. The engorged chambers expand the penis and the tunica albuginea, a membrane covering the two chambers, helps to sustain the erection. The erection ends when muscles in the penis contract to stop the inflow of blood and open the veins for blood outflow.
Physical causes of erectile dysfunction (ED) include cardiovascular disorders affecting blood supply to the penis, nerve damage, hormonal disorders, physical abnormalities of the penis, certain prescription drugs, and drug abuse. These factors can lead to difficulties in achieving or maintaining an erection
Psychological causes of ED encompass depression, stress, performance anxiety, and traumatic experiences. These psychological factors can significantly impact sexual function and contribute to the development or exacerbation of erectile dysfunction
Chronic illnesses such as diabetes, high blood pressure, nerve disease or damage, multiple sclerosis, atherosclerosis, and heart disease can damage the nerves and arteries to the penis, resulting in ED
Poor lifestyle choices such as smoking, excessive alcohol intake, being overweight, and lack of exercise can also contribute to erectile dysfunction
Pelvic surgery can potentially injure nerves and arteries near the penis, leading to difficulties with erections
Additionally, medications such as blood pressure drugs, antihistamines, antidepressants, tranquilizers, appetite suppressants, and cimetidine, an ulcer drug, can have adverse effects on erectile function. Hormonal abnormalities, such as low levels of testosterone, are also known to be associated with erectile dysfunction
The prevalence of ED may increase with age as well

These diverse factors can contribute to the development of erectile dysfunction, highlighting the multifaceted nature of this condition.
Treatment options may include :
Oral or locally injected drugs
Extracorporeal Shock Wave Therapy or ESWT is a type of treatment for ED. It is a low intensity shockwave treatment when applied to different areas of the penis results in the stimulation of new blood vessel growth.
With more blood vessels, there is improvement blood flow to the penis which improves the ability to achieve a full erection.
