London Andrology: Leaders in Male Fertility & Men's Health
When it comes to male reproductive health, subspecialist expertise makes all the difference. London Andrology was founded on a simple belief: that men deserve the same depth of specialist care for fertility and sexual health that has long been available for other complex medical conditions.
Under the leadership of Professor Suks Minhas and Professor Tet Yap — two of the world's most respected andrologists — we have built the UK's most advanced centre for diagnosing and treating conditions affecting male fertility and sexual function.
Our patients come to us after years of unexplained infertility, after failed IVF cycles, after receiving diagnoses they were told were untreatable. Many leave with outcomes they had stopped believing were possible.

Who We Are
Professor Suks Minhas and Professor Tet Yap have worked in partnership for over 15 years. Together, they have developed treatment pathways that are not available anywhere else in the UK, combining microsurgical precision with a deep understanding of the hormonal, genetic, and lifestyle factors that affect male reproductive health.
Both professors hold substantive NHS consultant posts at leading London teaching hospitals and see private patients at London Andrology. They are internationally recognised as pioneers in andrological surgery and contribute to the academic research that shapes how male fertility is treated globally.
This is not a general urology practice that occasionally treats fertility problems. Andrology — the medical subspecialty focused entirely on male reproductive and sexual health — is everything we do.
Conditions We Treat
Our clinical scope covers the full range of male fertility and men's health conditions. Whether you have received a diagnosis elsewhere and want a second opinion, or you are at the very beginning of an investigation, we offer a structured, evidence-based pathway tailored to your situation.
Male Fertility Conditions
- Azoospermia (zero sperm count) — obstructive and non-obstructive
- Severe oligospermia (very low sperm count)
- High sperm DNA fragmentation
- Varicocele associated with impaired fertility
- Retrograde ejaculation
- Male factor infertility in the context of IVF failure or recurrent miscarriage
- Post-vasectomy infertility
- Fertility impairment following cancer treatment
- Genetic causes of male infertility (including Klinefelter syndrome, Y chromosome microdeletions)
Sexual Health & Function Conditions
- Erectile dysfunction — all causes and severity levels
- Peyronie's disease (penile curvature)
- Premature ejaculation
- Low libido and hypoactive sexual desire
- Testosterone deficiency (hypogonadism)
- Painful ejaculation or haematospermia (blood in semen)
Surgical & Anatomical Conditions
- Varicocele
- Hydrocele
- Epididymal cysts
- Undescended testicle (cryptorchidism) in adults
- Scrotal and testicular pain (orchalgia)
- Post-vasectomy pain syndrome
Our Treatment Pathways
Every patient at London Andrology begins with a comprehensive assessment. We do not offer one-size-fits-all protocols. Your pathway is designed around your specific diagnosis, your reproductive goals, and your overall health picture.
Step 1 — Detailed Consultation
Your first appointment with Professor Minhas or Professor Yap will typically last 45–60 minutes. We take a full medical, sexual, and reproductive history. We review all previous investigations and, where necessary, arrange our own diagnostic workup — including semen analysis, sperm DNA fragmentation testing, hormone profiling, scrotal ultrasound, and genetic testing.
Step 2 — Accurate Diagnosis
Accurate diagnosis is the most important step in male fertility treatment. Many men arrive having been told their results are "borderline" or that there is "unexplained" infertility — terms that often reflect a lack of specialist investigation rather than a genuine absence of findings. Our diagnostic approach is rigorous and subspecialist.
Step 3 — Tailored Treatment
Treatment may be medical (hormonal or pharmacological), surgical, or a combination of both. Where surgical intervention is appropriate, Professor Minhas and Professor Yap perform the most advanced microsurgical procedures available, including microTESE, microsurgical varicocelectomy, vasectomy reversal, and penile implant surgery.
Step 4 — Ongoing Support
We work closely with leading IVF units and fertility nurses, and we do not discharge patients without a clear plan. For many couples, the journey from diagnosis to successful pregnancy involves several steps — and we remain available throughout.
Advanced Surgical Expertise
Both professors are high-volume surgical andrologists. This matters enormously. Outcomes in complex andrological surgery — particularly in microTESE for non-obstructive azoospermia and in microsurgical vasectomy reversal — are directly linked to the number of procedures a surgeon has performed and their access to operating microscope technology.
At London Andrology, we use state-of-the-art operating microscopes and microsurgical instruments for all procedures requiring magnification. Our theatre teams are experienced in andrological surgery and our equipment reflects the standard of care found in the world's leading academic medical centres.
Surgical procedures we perform include:
- MicroTESE (microscopic testicular sperm extraction)
- TESE (testicular sperm extraction)
- PESA (percutaneous epididymal sperm aspiration)
- Microsurgical vasectomy reversal (vasovasostomy and epididymovasostomy)
- Microsurgical varicocelectomy
- Penile prosthesis implantation (inflatable and malleable)
- Surgical correction of Peyronie's disease
- Scrotal exploration and orchidopexy
- Microsurgical testicular denervation for chronic orchalgia
- Hydrocelectomy and epididymal cyst excision
Why Subspecialist Care Matters
The NHS provides essential services for male reproductive health, but subspecialist andrological care — particularly for complex conditions — is unevenly distributed, and waiting times for fertility-related investigations often exceed 12–18 months. Many conditions that are straightforward to treat when diagnosed early become significantly more difficult to manage with delay.
Choosing to see a subspecialist privately does not mean abandoning the NHS. Many of our patients continue their NHS fertility treatment alongside private andrology input. What it means is accessing a depth of expertise, a speed of investigation, and a range of surgical options that cannot currently be delivered consistently within NHS capacity constraints.
Our consultants hold positions at leading NHS teaching hospitals and maintain the same clinical standards across both settings. When you see Professor Minhas or Professor Yap privately, you are seeing the same clinicians who lead NHS andrological services.
A Patient-Centred Approach
We are acutely aware that patients attending a male fertility or sexual health clinic are often dealing with feelings of vulnerability, embarrassment, or grief. The experience of infertility in particular can be profoundly isolating, especially for men who may feel that their fertility problems are less acknowledged than their partner's.
Our approach is direct, honest and compassionate. We will tell you clearly what we find, what it means, what your realistic options are, and what success in your individual case is likely to look like. We do not offer false reassurance, and we do not pursue interventions that the evidence does not support.
Every patient at London Andrology is seen by a consultant — not a registrar, not a nurse practitioner. Your care is led by Professor Minhas or Professor Yap personally, from initial consultation through to follow-up.
Our Academic Credentials
Professor Suks Minhas and Professor Tet Yap are not only clinicians — they are active researchers whose published work has shaped international guidelines in andrology. Their combined publication record includes hundreds of peer-reviewed papers, book chapters, and invited reviews in the world's leading urology and andrology journals. Both are invited faculty at major international urology congresses, including the European Association of Urology (EAU) and the American Urological Association (AUA) annual meetings.
This academic foundation means that the treatments available at London Andrology reflect current best evidence, not yesterday's standard of care.
Getting Started
If you have concerns about your fertility, sexual health or any condition affecting male reproductive function, the right first step is a comprehensive consultation with a subspecialist andrologist.
You do not need a GP referral to see us privately, though we are happy to accept referrals from GPs, fertility clinics, and other specialists.
To book a consultation with Professor Minhas or Professor Yap, contact London Andrology directly. We aim to offer appointments within one to two weeks and can accommodate urgent clinical situations where necessary.
Male Fertility FAQ's
A male fertility specialist (consultant andrologist) investigates, diagnoses, and treats conditions affecting male fertility, including low sperm count, poor sperm motility, hormone imbalances, and underlying reproductive health conditions. They provide tailored care to help understand fertility potential and improve reproductive outcomes.
Men are typically referred to a specialist when they and their partner have been trying to conceive for 12 months without success — or sooner if there are symptoms like sexual dysfunction, testicular problems, or concerns about sperm quality. Around half of couples experiencing infertility have a male factor involved.
Your specialist will take a detailed medical history and perform a careful physical examination. Initial testing usually includes a semen analysis to assess sperm count, motility, and morphology, and may be followed by blood tests or further investigations if needed.
Common tests include:
- Semen analysis (sperm count, motility, shape)
- Hormone blood tests
- Genetic blood tests
- Sperm DNA fragmentation tests
- Semen culture for infection
These tests together provide a comprehensive picture of fertility status.
Causes may include hormonal imbalances, varicocele, infections, azoospermia (no sperm), lifestyle factors, and other underlying medical conditions that can affect sperm production or quality.
Yes. Depending on the cause, treatment can include medical therapy, lifestyle changes, surgical interventions (e.g., varicocele repair), assisted reproductive techniques like ICSI, or referral for assisted conception.
A semen analysis is a non‑invasive test that evaluates sperm number, motility (movement), morphology (shape), and other factors in a sample of ejaculate to assess fertility potential.
If results are abnormal, your specialist will recommend further evaluation and discuss personalised strategies to address the cause and improve fertility outcomes.
The clinic is led by internationally recognised specialists, including Professor Suks Minhas and Professor Tet Yap, who bring extensive clinical and research experience in male reproductive health and fertility.
Advanced options include microsurgical sperm retrieval (e.g., micro‑TESE), vasectomy reversal, varicocele treatment, and tailored assisted reproductive technologies in collaboration with fertility clinics.
