About Dr Efstathios Theodorou

Mr Efstathios (Stathis) Theodorou is a highly experienced Consultant Gynaecologist and Fertility Specialist with over 25 years of dedicated experience helping patients achieve their dream of having a family.

With a warm, personalised approach, Mr Theodorou takes the time to truly understand your individual situation and builds a tailored treatment plan designed specifically for you — not a one-size-fits-all solution.

What Mr Theodorou can help you with:

Whether you are just starting your fertility journey or have faced previous setbacks, Mr Theodorou has specialist expertise in:

  • IVF and advanced fertility treatments
  • Recurrent IVF failure — helping patients who have struggled to conceive despite previous attempts
  • Recurent miscarriages - following natural conception or fertility treatment -
  • Low ovarian reserve — supporting patients with fewer eggs than expected for their age
  • Ovulation dysfunction including Polycystic Ovary Syndrome (PCOS/ PMOS)
  • Egg freezing (fertility preservation) — for medical or personal reasons
  • Egg donation and surrogacy
  • Preimplantation genetic testing (PGT - A / SR/ M) — to give embryos the best possible chance and screen where necessary for monogenic diseases
  • General gynaecology consultations for menstrual dysfunction, well women appoinmtent,  premature ovarian insufficiency.
  • Personalised treatment protocols tailored to your body and response

A specialist who stays at the forefront of fertility science

Mr Theodorou is passionate about translating the very latest research into real results for his patients. He has published multiple peer-reviewed studies in reproductive medicine and has held senior academic roles including supervising postgraduate students at University College London (UCL).

His career has included senior leadership positions at some of the UK's most respected fertility centres, including Deputy Medical Director and Head of Surrogacy at the Centre for Reproductive and Genetic Health (CRGH), and Medical Director at CARE Fertility London. He is an accredited trainer in pelvic ultrasound and embryo transfer, and regularly teaches GPs and healthcare professionals on the latest developments in fertility care.

What to expect as a patient

Mr Theodorou is known for making patients feel heard, supported, and informed at every step. His approach combines the most up-to-date science with genuine compassion — ensuring that your care is not only clinically excellent but feels right for you as a person.

Mr Efstathios Theodorou takes a different approach to fertility care. Rather than the fragmented experience common at high-volume clinics, where a consultant might only appear at a couple of key moments, he stays closely involved from your very first consultation right through scans and procedures to the end of treatment. His practice is grounded in evidence-based medicine, and he places real importance on talking patients through their options in plain terms, so every decision about their fertility is one they make with confidence and full understanding.

If you would like to discuss your fertility options, Mr Theodorou would be delighted to see you for a consultation.

I would like to express my sincere gratitude for the care and support we received. The consultant communicated with us clearly and honestly at every stage, which helped us feel informed and reassured. I always felt supported during our meetings and came away with a much clearer understanding each time. I especially appreciated his honest and realistic approach—he never made false promises, but instead gave us grounded hope and guidance, which meant a great deal to us. From the bottom of my heart, I am truly thankful. His care gave us the confidence and hope to believe things could work for us—and they did.

I owe so much to Dr Theodorou. We spent loads of time in research finding the right consultant and clinic for us, and I'm so pleased to say we chose correctly. He understood immediately that I wanted to give IVF everything I had on the first go without sacrificing my mental health, body, or finances. He helped me find the right balance of testing and treatment and really tailored everything to me. Because of his careful and kind manner, I was successful on my first and only cycle of ICSI. My son is now 5 months old, and I honestly still can't believe it's real.

We are absolutely thrilled to share our experience with Dr. Theodorou and his phenomenal team. After a challenging IVF journey, we were overjoyed to announce the arrival of our beautiful baby boy in April! We couldn't be more proud of ourselves, and eternally grateful to Dr. Theodorou, his wonderful secretary Megan who’s kindness and efficiency never went unnoticed , and all the staff who supported us every step of the way. From our very first consultation, Dr. Theodorou demonstrated an unparalleled level of expertise, empathy, and dedication. He took the time to explain his purposed treatment, answered all our questions with patience, and made us feel truly heard and understood. His calm demeanour and reassuring replies to our emails were a constant source of comfort during what was a very emotional process. We wholeheartedly recommend Dr Theodorou to anyone seeking fertility treatment. He is not just a doctor, but a true miracle worker and he made our dreams of becoming parents true.

5 stars is not enough for Dr. Efstathios! After years of unexplained infertility and unsuccessful treatment at another clinic, we were overjoyed to welcome our baby boy earlier this month. Recommended by a friend who had successful IVF treatment under his care, we traveled from Spain for the opportunity to work with him. He was incredibly patient and kind. When we faced challenges with egg and sperm quality, he swiftly adjusted our treatment plan, which ultimately led to our successful pregnancy. His team was incredibly supportive throughout the entire process, always available to answer our questions and ease our anxieties. We are forever grateful to him and his team for giving us the gift of parenthood. We highly recommend him and his team to anyone facing infertility challenges

Dr Theodorou was excellent throughout our treatment, he managed our expectations (age was not on my side) after 2 IVF treatments and only 2 embryos making it through genetic testing we had a successful transfer. Our baby boy is now 4 months old. Dr Theodorou and the wider team thank you is just not enough.
