Men’s Sexual Health & Libido
A men's sexual health blood test in Kingston, for when erectile difficulty, low libido or sexual symptoms have several possible drivers and one panel is not enough. The Sexual Health & Libido panel combines the male hormone axis (total and free testosterone, SHBG, prolactin) with thyroid function, the metabolic markers most relevant to erectile health (HbA1c, glucose, lipid profile) and a prostate marker (PSA), in a single venous draw. Reviewed by a GMC-registered doctor at our CQC-registered Kingston clinic.

Sexual symptoms in men are common, treatable, and frequently a useful window into wider health. The figures below are public-health data from the NHS, the British Society for Sexual Medicine and Prostate Cancer UK. They are included as context, not to alarm: most of what they describe is investigable in a single blood-test visit.
Sexual symptoms in men rarely have a single cause. Low testosterone, raised prolactin, thyroid dysfunction, undiagnosed diabetes or pre-diabetes, raised lipids and vascular disease, prostate enlargement, medications, sleep and stress can all contribute in different combinations. A focused testosterone-only panel can miss the diagnosis. The Sexual Health & Libido panel covers all the common blood-test contributors in one visit, so the reviewing doctor reads them together rather than working from a single marker. PSA is included as a screening adjunct, which is clinically defensible in men with sexual symptoms and removes the need for a separate prostate visit.
If your main concern is testosterone alone, the focused Testosterone & Hormone panel (£268) may suit. If you mainly want a prostate cancer risk score, see the Stockholm3 panel. For an STI screen, see the sexual-health pathway.
Total testosterone alongside SHBG and calculated free testosterone gives a true picture of biologically active testosterone. Prolactin identifies a treatable cause (prolactinoma) of low libido and low testosterone that single-marker testosterone testing often misses.
Thyroid dysfunction can cause fatigue, low libido and erectile difficulty, and corrects the picture of testosterone interpretation.
Undiagnosed pre-diabetes and type 2 diabetes are common causes of erectile difficulty through vascular and nerve effects. HbA1c shows the three-month average and is the most sensitive screen.
Lipid disturbance is part of the same metabolic-vascular picture that drives erectile difficulty, particularly in men over 40.
Included as a screening adjunct in men with sexual symptoms. PSA is not a definitive prostate cancer test; raised PSA can also reflect benign prostate enlargement, prostatitis, recent ejaculation or a urinary infection. The result is interpreted by the doctor in context. For a dedicated prostate cancer risk score, the Stockholm3 panel combines protein biomarkers, genetic markers and clinical inputs into a single score.
Each result is interpreted by the doctor against the appropriate reference range for you. Testosterone is most accurate from a morning sample (7am to 10am). PSA should not be tested within 48 hours of ejaculation, vigorous exercise (cycling), digital rectal examination or recent urinary infection, as all can falsely raise the result.
Most men book the blood test on its own and act on the doctor's outcome note. If you would like a clinical conversation in person, the panel pairs naturally with a 30-minute KONCEPT® GP consultation. For a fuller GP-led plan from the start, the Wellman Check is the personalised pathway.

A GMC-registered doctor at KONCEPT® reviews the request for clinical suitability before the appointment is confirmed.
Sexual symptoms rarely have one cause. This panel covers the male hormone axis, thyroid, blood sugar, lipids and PSA in a single venous draw so the doctor reads them together.
Testosterone has a marked diurnal pattern. Where possible we book testosterone-included panels in the morning.
Bloods are drawn in our CQC-registered Kingston clinic by an experienced practitioner. Samples processed by an accredited UK pathology laboratory.
A short outcome note is sent to your email, password-protected. Either normal, no follow-up needed, or GP review recommended (NHS GP or KONCEPT® GP at £149).
Erectile and libido symptoms benefit from a clinical discussion that brings the blood results together with history and lifestyle. Book a 30-minute KONCEPT® GP consultation (£149), or the fuller Wellman Check (£399).
Want a clinical conversation alongside the bloods? Book both in one go · the GP will see your results during the consultation.

Men with erectile difficulty, persistently low libido, fatigue with sexual symptoms, difficulty conceiving, or any combination of symptoms with no clear single cause. It is the right choice when a single-marker testosterone test is unlikely to be enough.
The male hormone axis (total testosterone, SHBG, calculated free testosterone, Free Androgen Index, prolactin), thyroid function (TSH, Free T4), blood sugar (glucose, HbA1c), full lipid profile, and PSA. Eleven blood markers in total.
PSA is included as a screening adjunct because some men presenting with libido or erectile symptoms also have prostate symptoms or are at the age where a baseline PSA is reasonable to obtain alongside the hormone and metabolic markers. PSA is not a definitive prostate cancer test; raised PSA can also reflect benign prostate enlargement, prostatitis, recent ejaculation or a urinary infection. The doctor interprets the result in context. For a dedicated prostate cancer risk score, the Stockholm3 panel is the better choice.
ED is recognised by NICE CKS and the wider clinical literature as a possible early indicator of cardiovascular disease, particularly in men under 60. The penile arteries are smaller than the coronary arteries, so vascular problems can become apparent there first. This is one reason the Sexual Health panel includes lipid and HbA1c markers alongside the hormone profile, and why the reviewing doctor reads the panel as a whole rather than as separate results.
Type 2 diabetes is associated with lower testosterone in some men, and low testosterone can in turn affect insulin sensitivity. HbA1c and testosterone are both included in this panel so the doctor can see whether the picture is hormonal, metabolic or both. Addressing diabetes risk often improves testosterone naturally; the reverse can also be true.
The reviewing doctor will recommend a private or NHS urology referral if PSA is persistently raised after a repeat test, if there are urinary or prostate symptoms (poor stream, frequency, nocturia, blood), or if the clinical picture warrants it. Most ED in men under 60 is initially worked up in primary care with a focus on cardiovascular and metabolic causes; urology referral typically comes when those have been addressed.
Morning, ideally between 7am and 10am. Fast for 10 to 12 hours (water only) for accurate glucose and lipids. Avoid ejaculation, vigorous exercise (cycling) and digital rectal examination for 48 hours before to keep PSA reliable.
Raised PSA in isolation is not a diagnosis. The doctor will repeat the PSA after addressing reversible causes (recent ejaculation, exercise, infection) and will recommend onward urology referral (NHS or private) where appropriate. The Stockholm3 panel can also help guide whether MRI or biopsy is needed.
A confirmatory second early-morning sample is recommended per NICE CKS guidance, alongside a discussion of contributing factors. If both samples confirm low testosterone, specialist referral is offered. KONCEPT® does not initiate long-term testosterone replacement therapy from a single panel result.
Most results within 2 to 5 working days, sent securely to your email, password-protected.
No. You can book online, in person, or add the panel during a GP consultation at KONCEPT®.
The Wellman Check (£399) is the GP-led pathway: 30-minute personalised consultation, examination, BP, BMI, PSA on request, plus a 10 to 15 minute follow-up after any investigations. Blood tests are not included as standard but you get 10% off any Men's Blood Test if the GP identifies a clinical need. The Sexual Health blood panel (£388) is the right choice when you want the markers tested first and a doctor to review them; the Wellman Check is the right choice when you want the conversation first.
Home-kit sexual-health packages typically measure testosterone alone or testosterone with SHBG, on a finger-prick sample taken whenever the kit arrives. At KONCEPT® the panel is a venous draw, morning-timed where possible, with eleven markers interpreted together by a GMC-registered doctor. Review and outcome note included in the £388 panel price.
The NHS provides comprehensive care and remains the right route for many men. KONCEPT® complements that care for men who want hormone, metabolic and prostate markers in one visit, on their own timing, interpreted together.
