Erectile Dysfunction (ED) is a multifaceted condition that impairs the ability to achieve or sustain an erection. It can occur due to a variety of factors, such as poor mental health, other comorbidities (like cardiovascular disorders, diabetes, hypertension, etc.), age, hormonal imbalance, traumatic events (spinal cord injury, pelvic injury), or medications (antipsychotics, antidepressants, etc.). Therefore, different tests are run for ED diagnosis.
