Comprehensive Blood Test for Investigating Impotence
Our Impotence Profile Blood Test (IMPO) is a comprehensive laboratory blood test designed to investigate common medical conditions that may contribute to impotence (erectile dysfunction). Erectile problems can be influenced by hormone imbalances, diabetes, cardiovascular risk factors, thyroid disorders, prostate health, and other underlying medical conditions.
This profile measures a carefully selected range of biomarkers to help identify possible physical causes of impotence and provide valuable information for discussion with your GP or specialist.
The price includes professional venous blood collection at your nearest participating Superdrug Health Clinic, making the testing process convenient and straightforward.
All samples are analysed by a UKAS-accredited ISO 15189 accredited medical laboratory, ensuring the highest standards of quality, accuracy and reliability.
What Does This Test Measure?
The Impotence Profile includes:
- Lipid Profile
- Total Cholesterol
- HDL Cholesterol
- LDL Cholesterol
- Triglycerides
- Glucose
- HbA1c
- Thyroid Stimulating Hormone (TSH)
- Prolactin
- Total Testosterone
- Free Testosterone
- Prostate Specific Antigen (PSA)
- Sex Hormone Binding Globulin (SHBG)
- Free Androgen Index (FAI)
Together, these tests evaluate metabolic health, cardiovascular risk, hormone balance, thyroid function and prostate health—all of which can play an important role in erectile function.
Why Choose This Test?
This profile may help investigate:
- Impotence (erectile dysfunction)
- Difficulty maintaining an erection
- Reduced libido
- Suspected testosterone deficiency
- Hormonal imbalance
- Fatigue
- Reduced physical performance
- Diabetes-related sexual dysfunction
- Cardiovascular risk factors
- Thyroid disorders affecting sexual health
Why Are These Tests Important?
Testosterone
Low testosterone is one of the recognised causes of reduced libido and erectile dysfunction. It may also contribute to:
- Low energy
- Reduced muscle strength
- Low mood
- Decreased sexual desire
Free Testosterone, SHBG and Free Androgen Index
Total testosterone alone may not always reflect the amount of biologically active testosterone available to the body.
By measuring SHBG, Free Testosterone and calculating the Free Androgen Index (FAI), this profile provides a more complete assessment of androgen status.
Prolactin
Raised prolactin levels may suppress testosterone production and reduce sexual function, making it an important investigation in men with impotence.
Blood Glucose and HbA1c
Diabetes is one of the leading medical causes of erectile dysfunction. Persistently elevated blood glucose can damage both nerves and blood vessels that are essential for normal erectile function.
HbA1c provides an indication of your average blood glucose over the previous 2–3 months.
Lipid Profile
Raised cholesterol and triglyceride levels may contribute to narrowing of blood vessels (atherosclerosis), reducing blood flow to the penis and increasing the risk of erectile dysfunction.
Thyroid Stimulating Hormone (TSH)
Both underactive and overactive thyroid disorders can affect sexual function, libido and overall wellbeing.
PSA
Prostate Specific Antigen (PSA) is included as part of the overall assessment of men’s health. PSA results should always be interpreted in conjunction with your age, symptoms and clinical history.
