Specialist men's health, male fertility and sexual medicine at Marylebone Diagnostic Centre
Marylebone Diagnostic Centre provides an integrated urology and andrology pathway in Central London, combining specialist assessment with advanced diagnostic testing and treatment.
Patients requiring consultant urological or andrological assessment can access specialist care with Mr Giulio Garaffa, Consultant Urological Surgeon, alongside MDC's diagnostic services including semen analysis, sperm DNA fragmentation, hormone testing, sexual health testing and erectile dysfunction assessment.
Our services are delivered and coordinated across two Baker Street locations, helping patients move from their initial concern to investigation, specialist assessment and follow-up without having to organise every stage themselves.
You do not need to know which test or specialist you require before contacting MDC. Our urology and andrology pathway can help patients with:
For concerns involving the urinary system, kidneys, bladder, prostate or male reproductive system. Depending on your symptoms, initial investigation may include blood tests, kidney function, urine testing, microscopy or culture, followed by specialist referral where appropriate.
Explore General Urology →Erectile dysfunction can have several possible contributing factors, including vascular, hormonal, metabolic, neurological, medication-related and psychological factors. MDC can provide appropriate blood and hormone investigations, andrology referral and low-intensity shockwave therapy for suitable patients.
Explore Erectile Dysfunction →MDC provides a comprehensive male fertility diagnostic pathway including semen analysis, sperm DNA fragmentation, male hormone testing, fertility blood tests and specialist andrology referral. Further investigation can be arranged according to the patient's history and results.
Explore Male Infertility →Patients concerned about prostate health can access private PSA blood testing, alongside relevant urine, kidney and general blood investigations where appropriate. An abnormal PSA does not automatically mean prostate cancer — results need to be considered in clinical context, and MDC can facilitate specialist urology assessment where required.
Explore Prostate & PSA Concerns →Symptoms such as burning when urinating, urinary frequency, urgency, recurrent infections, difficulty urinating or changes in urinary flow may require urine and/or blood investigation. MDC provides urinalysis, urine microscopy and urine culture testing, with further clinical referral when necessary.
Explore Urinary Symptoms & Recurrent UTIs →Peyronie's disease can cause penile curvature, discomfort and difficulties with sexual function. MDC can help patients access specialist andrology assessment, with erectile-function and other investigations arranged where clinically relevant.
Explore Peyronie's Disease →Phimosis describes a foreskin that is difficult or impossible to retract fully. The appropriate treatment depends on the cause and severity — MDC can arrange urology or andrology assessment, with infection or sexual-health testing where clinically indicated.
Explore Phimosis / Tight Foreskin →A short penile frenulum can cause discomfort, pulling or tearing, particularly during sexual activity. This generally requires clinical assessment rather than laboratory testing. MDC can help arrange an appropriate urology or andrology consultation.
Explore Short Frenulum →A hydrocele is a collection of fluid around the testicle that can cause scrotal swelling. Assessment may involve specialist examination and scrotal ultrasound, which MDC can help coordinate through the appropriate referral pathway.
Explore Hydrocele →Penile curvature present from birth can sometimes cause difficulty or discomfort during sexual activity. MDC can facilitate specialist andrology assessment to determine whether further investigation or treatment should be considered.
Explore Congenital Penile Curvature →Premature ejaculation is common and can have several contributing factors. MDC can arrange appropriate andrology assessment, with selected hormonal or other investigations where clinically indicated, rather than automatically performing unnecessary testing.
Explore Premature Ejaculation →Testicular symptoms should be appropriately assessed. Depending on the presentation, this may require clinical examination, laboratory investigation and/or scrotal ultrasound. MDC can help coordinate the relevant specialist and imaging pathway. Important: sudden or severe testicular pain can require urgent medical assessment and should not wait for a routine appointment.
Explore Testicular Pain, Lumps or Swelling →Blood in the urine — haematuria — should not simply be ignored. Initial investigation may include urinalysis, microscopy, culture, kidney-function testing and other blood investigations, but specialist urological assessment may also be required depending on the circumstances.
Explore Blood in the Urine →MDC can coordinate several investigations within the same patient pathway.
Depending on the clinical question, testing may include:
View Blood & Hormone Testing →Note: We do not recommend that every patient automatically undergo every test. The appropriate investigation depends on the symptoms, history and clinical circumstances.
MDC provides laboratory investigation of urine for appropriate clinical indications. Testing can include:
View Urine Testing, Microscopy & Culture →This may help investigate urinary symptoms and suspected infection and guide appropriate clinical follow-up.
MDC provides private semen analysis in Central London for the investigation of male fertility. Semen analysis assesses important parameters including:
View Semen Analysis →Patients requiring additional investigation can continue through MDC's male fertility pathway.
Sperm DNA fragmentation testing examines DNA integrity within sperm and provides different information from conventional semen analysis. It is not required for every patient — it may provide additional information in selected fertility circumstances, particularly when recommended following fertility assessment, previous results or reproductive history. MDC provides sperm DNA fragmentation testing alongside conventional semen analysis and male fertility investigations.
View Sperm DNA Fragmentation Testing →Where broader investigation is appropriate, MDC can combine semen testing with relevant male reproductive hormones and other blood investigations. This can help investigate different aspects of male reproductive health rather than relying on a single result.
View Male Fertility & Hormone Profiles →MDC provides a structured pathway for patients experiencing erectile difficulties: clinical assessment → hormonal and metabolic blood testing → specialist andrology assessment where required → treatment options. For appropriate patients, MDC provides low-intensity shockwave therapy for erectile dysfunction.
View Erectile Dysfunction Assessment & Shockwave Therapy →Note: Shockwave therapy is not appropriate for every patient or every cause of erectile dysfunction, so assessment remains important.
Some urological and andrological conditions cannot be adequately investigated using blood or urine tests alone. Where clinically appropriate, MDC can help coordinate referral for ultrasound or further imaging. This may include investigation involving the:
View Ultrasound & Imaging Referrals →The appropriate scan depends on the patient's symptoms and clinical assessment.

MDC's erectile dysfunction pathway is supported by Mr Giulio Garaffa, Consultant Urological Surgeon, with specialist expertise in andrology, male sexual medicine and erectile dysfunction.
Rather than treating ED as an isolated symptom, our pathway can combine specialist assessment with appropriate investigations including hormone testing, metabolic and cardiovascular risk markers, sexual health testing and other diagnostic assessment where clinically indicated.
Some patients come to MDC knowing that they need a specialist. Others begin with diagnostic testing and require specialist review following their results.
MDC can refer patients to experienced consultant urologists and andrologists when specialist assessment is appropriate. This is particularly relevant for conditions such as:
The objective is simple: Get the appropriate investigation, see the appropriate specialist and understand the next step.
You don't need to organise every stage yourself.
You can book an existing MDC service directly or contact us if you're unsure where to begin.
Depending on your circumstances, this could involve blood, urine, semen or other diagnostic testing.
Your results can help determine whether further clinical investigation is appropriate.
Where required, MDC can help coordinate referral to an experienced urologist or andrologist.
The next step may involve additional testing, ultrasound/imaging referral, treatment or monitoring.
MDC's urology and andrology pathway operates across our two locations on Baker Street in Marylebone, Central London.
This allows diagnostic testing, specialist pathways and follow-up to be coordinated around the patient rather than treating each appointment as an isolated service.
For many patients, this means fewer disconnected appointments and a clearer understanding of what happens next.
MDC brings laboratory investigation and appropriate specialist referral into a coordinated pathway.
Access semen analysis, sperm DNA fragmentation and reproductive hormone testing through MDC.
A wide range of relevant investigations can be arranged from our Baker Street diagnostic centre.
Where laboratory testing isn't enough, patients can be directed towards appropriate urology or andrology expertise.
Investigation, specialist pathways and shockwave therapy are available for suitable patients.
Ultrasound and further imaging can be coordinated where clinically appropriate.
Access services across two Baker Street locations in Marylebone.
That's completely fine. A common problem in private healthcare is asking patients to decide which investigation they need before they have been properly assessed.
At MDC, you can tell us what is concerning you, and we can help identify the appropriate starting point. That may be a laboratory test, a diagnostic profile, a urology/andrology consultation, or an imaging referral.
The aim is not to perform the greatest number of tests. The aim is to help you take the appropriate next step.
Tell us what's concerning you and we'll help identify the right test, profile or specialist referral.
