Fertility Treatments

Implantation Clinic

Here to help when starting again feels hard. We provide specialised care for patients after previous unexplained failures, combining advanced immunology diagnostics with personalised treatment to maximise your chances of pregnancy.

What is the Implantation Clinic?

The Implantation Clinic at London Women’s Clinic is designed for patients who have experienced failed embryo transfers despite good-quality embryos. Using advanced validated techniques, we study the immune environment of the womb lining to better understand factors that may affect implantation. Research* shows that endometrial immune profiling can identify key factors contributing to recurrent implantation failure, helping guide personalised treatment.

  • Using a range of advanced immune profiling tests, the clinic identifies factors that may prevent embryo implantation.
  • Based on results, we tailor treatment to address immune imbalances, with interventions aimed at restoring immunological balance in the endometrium.

The tests involve an out-patient procedure and our team provides support and guidance throughout the process to ensure your comfort and understanding.

Who is the Implantation Clinic suitable for?

The Implantation Clinic is designed for patients experiencing repeated embryo transfer failures with good quality blastocysts, who are seeking personalised insight into why implantation has not occurred.

It can be suitable for individuals who have undergone:

  • IVF or ICSI
  • IVF or ICSI with Preimplantation Genetic Testing (PGT-A)
  • Egg donation cycles

Our team supports you with tailored assessments to help understand the factors affecting implantation and guide the next steps in your fertility journey.

How does the Implantation Clinic work?

The Implantation Clinic is designed to better understand the environment in which implantation takes place. By carefully assessing your endometrium during a controlled cycle, our specialists can develop a personalised treatment plan based on your individual results.

Successful implantation depends not only on embryo quality but also on the health and readiness of the womb lining. Research from Dr Mona Rahmati and Professor Nick Macklon shows that advanced endometrial testing can identify factors affecting implantation, helping to guide personalised treatment plans rather than relying on trial-and-error approaches.*

*Endometrial immune assessment in patients with a history of previous euploid blastocyst failure.

Step 1

Initial appointment with a specialist, via referral or self-referral, to review your history and eligibility.

Step 2

You will be prepared in a medicated “mock” HRT cycle for endometrial testing. During this stage, you’ll take prescribed medication to recreate the natural hormonal environment and ensure your womb lining is ready for the biopsy.

Step 3

Conducted during a specific time in your cycle, including:

  • Hormonal blood tests
  • Pelvic ultrasound scans
  • Endometrial biopsy (a small sample of the womb lining is collected and sent for analysis)

Important note: For optimal results, your frozen embryo transfer (FET) should take place within six months of your endometrial biopsy.

Step 4

Laboratory analysis identifies potential causes of implantation failure and guides treatment recommendations.

Step 5

Results reviewed with your specialist to set a personalised treatment plan. In rare cases, tests may need to be repeated.

We started our IVF process with LWC around a year ago. It felt very daunting and a long road ahead, and the entire team were so supportive and explained everything so clearly. When we were undergoing the egg retreival and transfer, the team were so kind and we felt really looked after. We have now welcomed our little girl and after years of trying, we wouldn't have gotten here without the support and guidance given by LWC. Thank you all!

I've recently completed a round of egg freezing with London Women's Clinic harrow and I couldn't recommend them as a clinic more. Carla and Ana-Maria quite literally held my hand throughout the entire process, making me feel really relaxed and supported. It's made such a stressful experience super positive and if anyone is thinking of using them, I'd absolutely recommend them!

I undertook Kind IVF, which even though is nurse led as opposed to consultant led, the care, professionalism and knowledge is there. The nurses consult with consultants during your protocol, so the difference really is you see the nurses instead. The medication doses are less and less medication, but this doesn't mean it will be less effective, it is an option worth exploring, as the cost is less and can open the door when more traditional ivf is out of reach. I am currently pregnant having gone through the kind ivf protocol one time.

We will be forever grateful to London Women's Clinic Bromley for helping us achieve what once felt impossible -- welcoming our beautiful, healthy baby boy in November 2025. Our IVF journey was emotional, overwhelming at times, and deeply personal, but from the very first appointment we were met with nothing but kindness, compassion, and unwavering support. Every step was clearly explained, we were kept fully informed throughout, and there was always someone available to answer our questions or simply reassure us when we needed it most. We never once felt like just another patient -- we felt truly cared for. Dr Malini, Sarah, Nicky (Nikita) and Dom were exceptional and will always hold a very special place in our hearts. Their warmth, patience, and genuine kindness made the process so much easier to cope with. They made us feel safe, comfortable, and supported during some of the most vulnerable moments of our lives. Every nurse, embryologist, and member of staff we encountered was wonderful. We honestly cannot recommend London Women's Clinic Bromley enough to anyone struggling with fertility or facing similar challenges. The dedication, empathy, and expertise of this team has changed our lives forever. We hope to take the clinic up on their offer to visit with our little miracle, who we are endlessly thankful they helped bring into this world. Thank you from the bottom of our hearts. Lucy & Sayed

My journey with egg freezing in the LWC has been amazing. I had started consultations with another provider before but didn't feel comfortable there, and I'm SO GLAD I listened to my instinct and went to this clinic! The whole team was so knowledgeable and supportive throughout, but also just lovely. I would recommend the clinic, ESPECIALLY if you are worried about the process and feel emotional, the understanding and support here is way beyond what I was hoping for!!!

This was my first fertility treatment, and I cannot express enough how thankful I am to have chosen LWC and to have been treated at the Harrow clinic. I would highly recommend it to anyone considering starting their fertility journey! From the start, I appreciated how transparent the admin team was about all the costs involved at every stage, giving clear ranges when the decision depended on how the treatment would go. I am also extremely grateful for their support in helping with securing financing, even when I decided to move forward at short notice. They took the time to schedule calls to answer my questions, and I truly felt listened to and cared for as a patient. At the Harrow clinic, I experienced an exceptionally caring and positive environment. All the nurses were highly professional while also being incredibly comforting and supportive. I would especially like to thank Ana Maria, who was there throughout the process, offering practical advice based on her own experience, a hug when needed, and making the entire journey feel much more like home. I would also like to thank Carla for her positivity, high energy, and encouragement during difficult moments, and Laura for her empowering and reassuring approach to the injections. Dr Goswami was also outstanding--extremely professional and clear in her advice. She carefully adjusted the treatment to aim for the best possible outcome while prioritising safety and minimising risks. I am also very grateful for the support groups organised by the clinic. Through these, I met incredibly brave and empowered women and couples. Sharing this journey with some of them made the experience far more bearable and positive. Thank you to everyone at the Harrow clinic and LWC for your incredible support!!

We had a very positive experience at this IVF clinic and would highly recommend it. From the very beginning, we felt well supported and looked after throughout the entire journey. A special thank you to Safak, our patient coordinator, who was incredibly helpful and always very quick to respond. We would also like to thank Princess, the receptionist, as well as the Italian receptionist whose name we unfortunately don't remember, for always being kind and welcoming. We are extremely grateful to Dr Suraya, who performed many of our scans and was exceptional throughout the process, and to Dr Rao, who followed our journey step by step with great care, professionalism and attention. Finally, a big thank you to all the nurses, especially Hannah,Ella and Paige, for their support, kindness and professionalism. Overall, we felt very well cared for and supported, and we truly recommend this clinic to anyone considering IVF!

We don't know where to begin, this place truly is wonderful. So so comforting and welcoming. Every single staff member went above and beyond and really felt like family. We couldn't be more appreciative of everyone who helped us on our way to creat our little one, who is cooking away nicely at 20 weeks. From choosing a sperm donor to my egg collection and then to getting my wife pregnant with the embryos a few months later, it was so stress free and we felt supported every single step of the way. We can't thank all the lovely wonderful ladies at the Brentwood clinic enough for what they have helped us achieve- and of course the amazing people at the Harley street clinic for doing the procedures who were just as welcoming! Thank you all so so much, we can't wait to bring our little man to meet you all when we are ready to try for baby number 2 xxxxx

Following a seminar I attended at LWC, I arranged a consultation with Dr. Naware who specialises in fertility for women over 40. It was a refreshing experience. Dr. Naware is empathetic, kind and thorough. The follow up from the clinic was excellent, with Safak, Patient Coordinator, providing regular updates.
