Sexual Health & PotencyScreening
A discreet clinical investigation into libido, erectile function (ED), testosterone status, and overall reproductive vitality.
Understanding Sexual Health & Potency
Sexual health is one of the most sensitive — and most revealing — barometers of overall health in men. Libido, erectile quality and sexual performance depend on an intricate collaboration between hormones, blood vessels, nerves and psychology. When something shifts, it is rarely random: measurable changes in testosterone, thyroid function, blood sugar or vascular health are frequently involved, and most are treatable once identified.
Many men tolerate a gradual decline in sexual vitality for years, assuming it is simply age. Sometimes it is; often it is not. Low free testosterone, raised prolactin, early diabetes and subclinical vascular disease are all common, all detectable through blood testing, and all far more responsive to treatment when caught early. Investigating is not vanity — the same vascular processes that affect erections also affect the heart.
A structured blood work-up is the evidence-based first step recommended in UK clinical guidance for persistent sexual health concerns. It either identifies a physical contributor to address, or provides genuine reassurance that redirects attention to sleep, stress, relationships or medication side-effects — all equally solvable with the right information.
Risk Indicators
- Erectile Dysfunction (ED)

Expert Care by Luciana
Our experienced registered nurse performs gentle blood draws with complete discretion. Your results are explained in a clear written report.
Diagnostic Path
Identifying clinical markers associated with sexual health & potency requires a high-resolution laboratory profile. Below are the recommended diagnostic assessments specifically calibrated for this concern.
Our Erectile Dysfunction Blood Screening investigates the full physical picture in one panel: lipids and HbA1c (vascular causes), thyroid function, total and free testosterone, SHBG, prolactin and PSA. The Male Hormonal Health Screening focuses on the endocrine axis — testosterone, SHBG, Free Androgen Index, FSH, LH and prolactin — revealing where in the system any imbalance originates. For the broadest context, the Platinum Full Body MOT for Men covers 60+ markers including cardiac and prostate markers.
When to See Your GP Urgently
Screening is for people without acute symptoms. If any of the following apply, please seek medical care first:
- Sudden complete loss of erections with pain — seek urgent medical care
- Erectile difficulties with chest pain or breathlessness on exertion — see your GP promptly
- A testicular lump or swelling — see your GP this week
- Blood in urine or semen — see your GP
Frequently Asked Questions
Is declining sexual performance just part of ageing?
Some change with age is normal, but a marked or progressive decline is not something to simply accept. Hormonal, vascular and metabolic contributors are common and frequently treatable. Blood testing distinguishes what is age from what is addressable.
Which test should I choose?
If erectile function is the main concern, the Erectile Dysfunction Blood Screening covers both vascular and hormonal causes. If low desire, energy and mood dominate, the Male Hormonal Health Screening maps the full hormone axis. Unsure? Book a "Decide in Clinic" appointment and our nurse will help you choose.
Is everything confidential?
Entirely. Private one-to-one appointments, results only to you through our secure portal, and nothing shared with your GP or anyone else unless you choose to share it.
What happens if my results show a problem?
Your written nurse report explains exactly what was found and what to discuss with your GP, who can prescribe effective treatments or refer to a specialist. Most findings — low vitamin D, borderline HbA1c, thyroid imbalance, low testosterone — have well-established management pathways.
