Andropause & Male Hormone Optimisation

Low energy, reduced libido, mood swings, weight gain, sleep disruption, and brain fog—if you’re experiencing these symptoms, it may not just be “getting older.”

You could be going through Andropause, also known as late-onset hypogonadism.

Andropause & Men’s Longevity Medicine

At our clinic, we are dedicated to providing a comprehensive, root-cause approach to health for everyone.

In line with this commitment, we are proud to introduce a pioneering men’s health programme led by Mr Stefanos Kachrilas, a Consultant Urological Surgeon and expert in andrology, functional medicine, and longevity science. His tailored, science-led approach helps men regain vitality, focus, strength, and hormonal balance—safely and sustainably.

What Is Andropause?

Andropause refers to the age-related decline in testosterone and other key hormones in men. Unlike the female menopause, it occurs gradually and is often missed or misdiagnosed.

Symptoms may include:

Fatigue and low motivation
Decreased libido and sexual performance
Loss of muscle mass or increased belly fat
Sleep disturbances
Anxiety or low mood
Cognitive decline or “brain fog”
Poor exercise recovery
Reduced confidence and resilience

This isn’t just “midlife”—it’s a clinical condition that can be tested, treated, and reversed.

Meet Mr Stefanos Kachrilas

We are honoured to partner with Mr Stefanos Kachrilas, an internationally recognised Consultant Urological Surgeon with over 20 years of distinguished experience. His work uniquely bridges three critical disciplines: specialist urology, functional medicine, and advanced longevity science, making him one of the few experts in the UK offering a truly integrative approach to modern male health.

Mr Kachrilas is a Fellow of the Royal College of Surgeons, the European Board of Urology, and has completed prestigious fellowships in Andrology and Endourology at leading NHS trusts. His extensive academic career includes authoring textbooks, publishing in numerous peer-reviewed journals, and holding ongoing research positions. He is a passionate educator, training the next generation of surgeons and speaking at international conferences on men’s health.

The Trifecta Approach: A Revolution in Men’s Health

Mr Kachrilas has pioneered the proprietary Trifecta Approach, a model that moves beyond symptom management to transform male ageing into a proactive, high-performance experience. This powerful synergy combines:

Conventional Medicine: Utilising accurate diagnostics, advanced hormone therapy, and world-class urological expertise.
Functional Medicine: A deep dive into metabolic, nutritional, and endocrine optimisation to correct underlying imbalances.
Longevity Medicine: Applying cutting-edge science, including mitochondrial support, cognitive therapies, NAD+ protocols, and biological age tracking to enhance cellular health.

This model doesn’t just restore health—it empowers men to build a robust foundation for a long and vibrant life.

Areas of Special Clinical & Academic Expertise

Andropause & Testosterone Replacement Therapy (TRT)
Erectile Dysfunction and Sexual Rehabilitation
Functional Metabolic & Mitochondrial Optimisation
Prostate Health & Post-Cancer Recovery
Male Fertility Preservation
Cognitive & Neurohormonal Ageing in Men
NAD+, Peptide, and Senolytic Therapies for Biological Ageing
Medical Education, Training, and Academic Publishing

A Vision for the Future of Men’s Medicine

Mr Kachrilas’s mission is to transform male ageing from a passive decline into a proactive pursuit of strength, clarity, and longevity.

“As a surgeon, scientist, and educator, I’ve seen how the fusion of clinical precision with root-cause thinking and longevity science can change lives. I’m committed to helping men restore their health, protect their performance, and age with vitality and dignity.”

Common Symptoms of Andropause

Do you experience any of the following?

Low libido or erectile difficulties
Fatigue or burnout
Mood swings or low self-esteem
Poor concentration or memory
Increased abdominal fat
Difficulty building muscle
Loss of purpose or drive

These are not inevitable signs of ageing. They’re treatable indicators of hormonal imbalance.

This allows for a precision-medicine approach to hormone optimisation, energy recovery, and long-term male health.

Dr. Stavy been patiently going throughand tackle my joint pain problem, instead of constantly taking med to cease my pain when it hits, with Dr. Stavy’s treatment, which focus more on improving my inner body and strengthen the overall health.

Dr Stavy was a God sent angel that saved me from GP appointments, tons of harmful medicines and long waiting list nhs referral. I was at the end of the rops, hopeless, physically and mentally broken… thanks to Dr Stavy and their team, I haven’t been back to GP, I am not taking any of those nasty steroid tablets and immune therapy injections… I cannot recommend her enough and both my husband and a friend are so happy that they see Dr Stavy after i recommended. Functional medicine and holistic therapies take a bit of time, patience and dedication to treat the causes of the issue but Dr Stavy makes the journey easy, she is so knowledgeable, kind, friendly and caring. If you’re like me in 6 month ago and reading reviews to decide which Functional medicine Dr to choose, don’t hesitate to see her, she is the best.

I have been treated by Dr Stavy for a few months now. She has a kind and gentle approach, which is invaluable when talking about something as sensitive as health. She listens to what I say and takes my concerns seriously, which is wonderful and refreshing.

There is still some way to go, but through changes to diet, my IBS, which I had for about 15 years has gone, my sinus issues have greatly improved and I am no longer dizzy. I’ve also lost quite a bit of weight, which is a great and has improved my confidence.

Having a previous bad experience with homeopathy doctors, I was sceptical. Dr Stavy though is an excellent practician, hit the point from our first meeting, but most important she is an uderstanding person, with great instinct and very supporting towards me! Qualities I value the most! Thank you Dr Stavy for everything, I am lucky to have found you!

It was 20 years ago, that I met Stavroula! Kidney stones and extracorporeal lithotripsy did not work. The large stone did not break and I was getting ready for surgery. Stavroula took it upon herself to help me! About a year later, with patience and persistence and a lot of colic, the stone came off and came down! That’s how we started and “tied”!!!
Since then, whatever problem I had, pathological, orthopedic but also psychological, I went to Stavroula!!
Always with a sweet talk, with patience but also with scolding whenever needed!
Thank you my dear!!!
Be strong!!!

17:28 17 Apr 24

Dr stavvy is the best! I Couldn’t recommend her enough! In 2021 I was at a point where I was going to need a life altering operation then I come accross dr Stavy and within 3/4 months I was back to my normal self and pregnant! All with natural and homeopathy treatments. I still have a routine check up with Dr Stavy to this day to make sure everything’s as it should be. I owe this lovely lady my life and she has changed my whole outlook on modern medicine. If I were ever to be sick again Dr Stavy would be the first person I would call before any doctor!!!

Sue H.

14:45 04 Sep 22

I have been in touch with Dr Stavy for 5 or 6 years now and find the Functional medicine approach very helpful. I’ve had ME for a long time and conventional medicine is only able to treat/suppress the symptoms whereas the tests I’ve done for Dr Stavy have helped pinpoint some of the causes of my symptoms. She is easy and sympathetic to talk to and always very encouraging. She feels like a friend and it is good to know that she is there to support me when needed. I have also found her homeopathic treatment helpful.

Dimitris P.

07:36 24 Aug 22

First of all I have to say that Dr Stavy is a wonderful person. She is so kind and trying always to help you. Our relation is very old since last decade and we are very happy to have her in our life. I started alone as a single person and now we are seeking her advice as a family. Even that she is not close to us, as she is living in UK, our relationship is very strong.

Dr. Stavy has been treating me since November 2020 and since my life has only been better. Her engagement with her patients, the professionalism, the genuine support and compassion make Dr. Stavy a special therapist that one can trust primarily as a human and definitely as a doctor. Highly recommended.
