ICSI
ICSI is a well established advanced IVF technique that gives couples facing male infertility the best chance of creating embryos and building their families.

What is ICSI?
Intracytoplasmic Sperm Injection (ICSI) is an advanced IVF lab technique in which a single sperm is selected and carefully injected directly into the centre of an egg. By bypassing natural barriers to fertilisation, ICSI is one of the most effective treatments for male infertility.
Globally, ICSI is widely used – often when sperm quality, movement or count may affect fertilisation – and has consistently strong success rates.
Who is ICSI suitable for?
ICSI may be recommended if there are challenges related to sperm quality, quantity, or motility. Around half of infertility cases involve sperm-related factors, making ICSI an important option for many couples.
It can also be used when:
- Previous IVF cycles have not resulted in fertilisation.
- Sperm need to be retrieved surgically due to obstruction or other rare conditions.
- Couples wish to maximise the chances of fertilisation in any IVF cycle.
Your fertility specialist will discuss whether ICSI is suitable for your individual situation, and in some cases, the decision may be made on the day of egg collection depending on sperm quality.
How Does ICSI Work?
ICSI is essentially an IVF cycle, with one key difference — in the lab, a single sperm is carefully injected into each egg to help fertilisation. Here are the initial steps:
Fertility medications encourage the ovaries to produce multiple mature eggs.
Eggs are retrieved via a short outpatient procedure.
Using a high-powered microscope and an ultra-fine needle, a single sperm is injected directly into each egg. Our embryologists carefully observe and select the most progressive and motile sperm for injection.
Fertilised eggs are carefully observed as they develop into embryos.
The healthiest embryo(s) are transferred into the uterus, with any additional viable embryos frozen for future use.
This precise and controlled process maximises the chances of fertilisation and a successful pregnancy.
ICSI Success in Numbers
Over 70% fertilisation rate with ICSI treatment
Since 2004, our expert teams have performed over 16,000 ICSI cycles, helping thousands of patients build their families.
Between 2022–2025, our embryologists injected 21,667 eggs using ICSI, achieving a fertilisation rate of over 70%. Fertilisation rates with ICSI are typically around 70–75%, making it one of the most reliable treatments for male infertility.
Our teams use advanced techniques and careful monitoring to maximise outcomes for every patient.
WHO WE TREAT:
- 90% of ICSI patients are heterosexual couples.
Of these, around 4% used PESA/TESE sperm samples (fresh or frozen)
SUCCESS BY AGE GROUP AFTER THREE TRANSFERS*:
- Under 38: 56% live birth rate
- 38 and over: 22% live birth rate
- All ages combined: 44% live birth rate

How Surgical Sperm Retrieval Supports ICSI Treatment
In rare cases where sperm cannot be ejaculated naturally, it is often possible to retrieve sperm surgically:
- Needle Aspiration: Extracting sperm directly from the testes or epididymis.
- Testicular Biopsy: Examining a small tissue sample for viable sperm cells.
Any sperm retrieved through these methods can then be used with ICSI to fertilise eggs, giving couples who might otherwise face limited options the opportunity to conceive.
ICSI Risks and Considerations
ICSI has been used worldwide for more than 30 years and follow up studies on children born continue to be very reassuring. Your fertility specialist can discuss any potential risks in detail, ensuring you are fully informed and supported in your decision-making.

‘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.’
