Understanding Lab Tests for Erectile Dysfunction
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Erectile dysfunction (ED) is a common condition characterized by the inability to achieve or maintain an erection sufficient for sexual intercourse. While there is no single blood test that directly diagnoses erectile dysfunction, laboratory testing plays a fundamental role in identifying underlying hormonal imbalances and other medical factors that may contribute to the condition.
Top Recommended Test
Testosterone, Total, Male, IA (MALES ONLY)
This test measures the total amount of testosterone in the blood, which is crucial for sexual function in males. Low testosterone levels can result in erectile dysfunction, reduced sexual desire, and other sexual health issues. This is often the first-line test for evaluating hormonal causes of ED.

Why Blood Testing is Important for Erectile Dysfunction
Erectile dysfunction can have multiple causes, including hormonal imbalances, cardiovascular issues, diabetes, and psychological factors. Blood tests are essential for assessing hormone levels, particularly testosterone, which plays a crucial role in male sexual function. Testing helps healthcare providers determine if hormonal deficiencies are contributing to ED and guides appropriate treatment decisions.
Other Relevant Tests
Testosterone, Free, LC/MS/MS
This test measures free testosterone, the biologically active form of testosterone that is not bound to proteins. Free testosterone provides a more accurate assessment of available testosterone for tissue use. Low levels of free testosterone can contribute to erectile dysfunction, making this test valuable for comprehensive hormonal evaluation.

Testosterone testing can help identify if low hormone levels are contributing to erectile dysfunction. However, ED is a complex condition that may involve multiple factors. A healthcare provider will interpret test results in conjunction with medical history, symptoms, and physical examination to develop an appropriate treatment plan.
