Can Your Blood Sugar Be Normal While Your Insulin Is High?
When patients think about diabetes or metabolic health, they usually think of blood sugar. That is understandable: glucose is one
October 21, 2026
Erectile dysfunction (ED) can be a sensitive and distressing condition affecting many men. It occurs when a man is unable to achieve or maintain an erection sufficient for sexual intercourse. While there are various factors contributing to this condition, blood tests can offer valuable insights into possible underlying causes.
Our clinics in London offer a range of blood tests specifically designed to identify the underlying cause of your erectile dysfunction, helping to guide you toward the most appropriate treatment options.
Blood tests play a crucial role in evaluating your hormone levels (which can significantly impact erectile function). Hormones such as testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin are commonly analysed as they are commom ED culprits. Low testosterone levels, for example, can contribute to ED, and identifying this imbalance through blood tests can guide hormone replacement therapy if necessary.
Erectile function also relies on a healthy blood flow to the penile arteries. Blood tests can assess markers such as cholesterol, triglycerides, and blood glucose levels, which help identify underlying vascular issues that may contribute to ED. High cholesterol and diabetes, for instance, can lead to blood vessel damage and reduced blood flow, affecting erectile function.
Blood tests can reveal underlying systemic conditions that may contribute to erectile dysfunction. Conditions like hypertension, hyperlipidaemia, and cardiovascular disease can affect blood vessel health, ultimately impacting erectile function. Detecting these conditions through blood tests aids in comprehensive treatment planning, ensuring both ED and the underlying systemic issues are addressed concurrently.
While primarily a physical condition, erectile dysfunction can also have psychological causes or implications. Blood tests can help rule out any physiological factors contributing to ED, allowing your doctor to focus on potential psychological causes such as stress, anxiety, or depression.
Blood tests are also valuable tools for monitoring and managing the effectiveness of ED treatments. By periodically assessing your hormone levels, lipid profiles, and blood glucose, your doctor can evaluate treatment efficacy and make necessary adjustments to optimise outcomes. Additionally, regular blood tests can help identify any developing health concerns that might impact erectile function, allowing for early intervention.
If you are experiencing erectile dysfunction, seeking professional medical advice is essential to understand your unique situation and explore the most appropriate treatment options available.
Common psychological conditions that can lead to erectile dysfunction could include:

Hormone testing should ideally take place before 10 am to ensure the most accurate results, as hormone levels can fluctuate throughout the day. If you are interested in testing your glucose or triglyceride levels, it is recommended to fast for 6 to 8 hours beforehand. This means you should avoid eating or drinking anything other than water during this period.
A healthcare assistant or nurse will take a sample of your blood, typically from your arm, and the entire procedure takes only a few minutes. They are trained to ensure the blood-drawing process is as painless and comfortable as possible. They will explain each step of the procedure, and always willing to answer any questions you might have. Afterwards, they will prepare your blood sample for the analysis.
Your results will be sent to you electronically via email within 12 hours after your procedure. This swift delivery ensures that you promptly receive your health information, enabling you (and your healthcare provider) to review and discuss your results in a timely manner.
