Testosterone

Most men who come to us about testosterone have already noticed something is off. Energy that used to recover overnight now takes days. A flatness in mood that does not lift. Weight gathering around the middle despite nothing changing in diet or exercise. A loss of sexual drive, or morning erections that have quietly disappeared. These are not inevitable signs of getting older. They are recognisable symptoms of testosterone deficiency, and they are worth investigating properly.

Testosterone deficiency is significantly underdiagnosed in the UK. Many men either do not connect their symptoms to a hormonal cause, or have tried an online test and found themselves managing a number without a clear picture of what it means or why it has happened. At Coyne Medical, we approach this as a whole-person consultation. Testosterone does not sit in isolation. It interacts with thyroid function, metabolic health, sleep, cardiovascular risk, and body composition. Understanding what is driving your symptoms requires looking at all of it, not just a single result.

A proper assessment involves two fasting morning blood draws, measuring both total and free testosterone alongside the broader hormonal picture. We review the results with you in full, explain what they mean, and discuss your options. If treatment is appropriate, we will manage that with you. If something else is driving your symptoms, we will find it.

Prostate Health

Prostate cancer affects one in eight men in the UK, making it the most common cancer in men. Like most cancers, it is most treatable when found early, and most early prostate cancer produces no symptoms at all. Screening is therefore something worth thinking about before anything feels wrong, not after.

The starting point is a PSA blood test. PSA, or prostate-specific antigen, is a protein produced by the prostate gland, and elevated levels in the blood can indicate cancer. It is a useful and widely available test, but it has a known limitation: PSA can be raised by benign prostate enlargement, inflammation, or infection as well as by cancer. A raised result does not automatically mean cancer is present, and a normal result does not entirely rule it out. Where PSA falls in the borderline range, we measure free PSA alongside total PSA to give a more accurate picture before deciding on next steps.

Where PSA is elevated, we offer Stockholm3 as a more precise next step. Stockholm3 is an advanced screening test that combines blood biomarkers, genetic markers, and clinical information including age and family history to calculate a personalised cancer risk score. A major clinical trial found it reduced unnecessary biopsies by 32% while maintaining the same accuracy in detecting clinically significant cancers. NICE has acknowledged its potential to improve the precision of prostate cancer screening, and it has been validated across different ethnic groups, which matters in a city as diverse as London.

Genetics also has a role in understanding prostate cancer risk. Variants in certain inherited genes, including BRCA2, are associated with a significantly higher lifetime risk of prostate cancer and with more aggressive disease. If you have a family history of prostate cancer, or of breast or ovarian cancer in close relatives, genetic testing may add a meaningful layer to your risk assessment. Our inherited cancer risk panel tests 35 genes including BRCA2 and HOXB13, both of which carry implications for prostate cancer risk, and can be arranged alongside or independently of a PSA assessment.

Erectile Function

Erectile dysfunction is common, and it is also commonly misunderstood. Most men who experience it assume it is a consequence of age, stress, or relationship issues. Sometimes it is. But in a significant proportion of men, erectile dysfunction is a vascular and hormonal signal — one that points to something else going on in the body that is worth finding and addressing.

The cardiovascular connection is the most important one to understand. Men with erectile dysfunction have a 45% higher risk of cardiovascular disease, a 55% higher risk of heart attack, and a 36% higher risk of stroke compared to men without it. Erectile dysfunction typically precedes symptomatic cardiovascular disease by two to five years. That window is not a reason for alarm. It is a reason to investigate. A man who comes to us about erectile function and leaves with a clear picture of his cardiovascular health, his testosterone levels, and his metabolic risk has used that window well.

Testosterone is the other piece. Low testosterone is a direct cause of erectile dysfunction in a significant proportion of men, and it is frequently missed because the sexual symptoms are attributed to other causes before anyone checks hormone levels. The two conditions overlap considerably: low testosterone reduces sexual desire and the physiological mechanisms that support erection, while the same metabolic risk factors that damage blood vessels also suppress testosterone production. Investigating both at the same appointment is not over-engineering the consultation. It is the clinically appropriate approach.

At Coyne Medical, an erectile function consultation begins with a full history and a blood panel that covers testosterone, cardiovascular risk markers, blood glucose, and relevant hormones, taken at the same appointment with results the following day. We can arrange further investigations where indicated, provide private prescriptions for oral medication where appropriate, and refer to a specialist urologist when you need specialist care. The goal is not simply to treat the symptom. It is to understand what is driving it.

Sexual Health

Sexual health testing is one of the most common reasons men visit us, and one of the most straightforward things we can help with. If you have a concern, the right move is a test, not a wait.

We offer a full range of testing for sexually transmitted infections including chlamydia, gonorrhoea, HIV, syphilis, hepatitis B, and hepatitis C. Tests are taken at your appointment and results are available the same day for most infections. Everything is handled discreetly and confidentially. If treatment is needed, we can prescribe at the same visit in most cases, so there is no need for a second appointment.

If you have questions about which tests are right for your situation, your GP will talk through this with you at the start of the appointment. There is no need to know in advance exactly what you need testing for.

Testicular Health

Testicular cancer is the most common cancer in men under 35, and the vast majority of cases are highly treatable when caught early. If you have noticed a lump, swelling, or change in one or both testicles, it is worth having it examined promptly rather than waiting to see whether it resolves. Our GPs can assess any concerns at the same appointment, and if you need to be seen by a specialist urologist, we will arrange that quickly.

Your complete health picture

For men who want to go beyond individual tests, our health screening packages bring everything together in a single appointment. Blood panel, cardiovascular risk assessment, body composition, and GP review, with optional add-ons including genetic cancer testing and a multi-cancer early detection blood test. The Advanced Screening is a strong starting point. The Complete and Ultimate packages add whole body MRI, VO2 max testing, and, at the Ultimate level, a 55 gene inherited cancer risk panel and pharmacogenomics report. Complete and Ultimate packages include a testosterone assessment as standard.
