If you’re exploring IVF, one of the first questions you’re likely to ask is, “What are my chances?” Success rates can feel like a lifeline of certainty, but they can also be confusing if you don’t know what influences them.
In the UK, IVF success rates are typically presented as the percentage of live births per embryo transferred. These figures are calculated annually and regulated by the Human Fertilisation and Embryology Authority (HFEA), making them a reliable benchmark. However, it’s important to understand that these averages don’t guarantee individual outcomes.
In 2022, patients aged 18-34 had the highest preliminary average live birth rate per embryo transferred at 35%. For patients aged 35-37, this rate increased from 19% in 2012 to 26% in 2022. Patients aged 38-39 saw an increase from 14% to 18%, while those aged 40-42 experienced a rise from 8% to 10%. Even for patients aged 43-44, the live birth rate per embryo transferred improved to 5% in 2022.
So, how do you know where you stand? Let’s look at what these numbers mean and what they don’t tell you.
Why success rates vary
IVF success rates are influenced by many factors, and some of the most significant include:
- Age and egg quality
Age is one of the most significant factors because egg quality declines over time. Younger individuals are more likely to have eggs that result in healthy embryos, making implantation and pregnancy more likely. This is why success rates for those under 35 are higher.
If you’re over 40, that doesn’t mean success is impossible. Options like using donor eggs or advanced screening techniques can help streamline the process by identifying embryos more likely to result in a successful pregnancy and reducing time to pregnancy. Our team at Care Fertility will guide you through the best options for your circumstances.
- Embryo quality
Embryo quality is critical because it determines the likelihood of implantation. The better the embryo, the higher the chances of it leading to a healthy pregnancy. Advances in embryology, such as time-lapse monitoring and preimplantation genetic testing, can help select embryos with the best potential.
- Your health and lifestyle
Your overall health plays a key role in IVF success. Maintaining a healthy BMI, avoiding smoking and excessing drinking, and managing stress can all improve your body’s readiness for pregnancy. Small changes in lifestyle can make a big difference, and our team is here to support you with advice and resources.
- Uterine health
A healthy uterine lining is essential for successful implantation. Issues like fibroids, polyps, PCOS, or endometriosis can impact success rates, but many of these challenges are treatable. Our advanced diagnostic tools can identify and address these issues early on.
- The clinic you choose
Not all clinics are the same, and success rates can be influenced by many factors, including patient demographics and advances in science. At Care Fertility, we combine world-class technology with a personalised approach, which is why so many patients trust us with their journeys.
What can you do to improve your chances?
While some factors like age are beyond your control, there’s plenty you can do to improve your odds:
- Start with a fertility check: This gives a clear picture of your current fertility health. Even if you’re not ready to start treatment, the sooner you do these checks the more prepared you can be.
- Consider lifestyle adjustments: Maintaining a healthy diet, exercising moderately, and managing stress can all help.
- Talk to a specialist early: Understanding your options sooner can help you make informed decisions and avoid delays.
- Ask about advanced options: Techniques like egg freezing, embryo freezing, and genetic testing can give you more control over your journey.
Our team at Care Fertility works with you to create a personalised plan, maximising your chances while offering support every step of the way.
What are the chances of IVF success?
Now, let’s talk numbers. According to the Human Fertilisation and Embryology Authority (HFEA), here are the average live birth rates per embryo transferred in the UK:
- Under 35: Around 32% of treatments result in a live birth.
- 35–37: Success rates drop to 26% per cycle.
- 38–39: Approximately 18% of cycles are successful.
- 40–42: Success rates fall to 10% per cycle, reflecting the natural decline in fertility.
- 43–44: Only 5% of treatments result in a live birth, due to reduced egg quality and quantity.
- We understand that seeing these numbers can feel overwhelming. But remember, they’re just averages. Your personal chances depend on your circumstances, and we’re here to explore every option to improve your odds.
Success is more than a statistic
When you see success rates, it’s easy to feel reduced to a percentage. But your story isn’t a statistic.
The truth is success rates are a helpful guide but not the full story. Your chances depend on a combination of personal factors and the care you receive. At Care Fertility, we pride ourselves on achieving success rates that consistently exceed national averages.
We don’t just look at the numbers—we look at you. From advanced testing to tailored treatments, every decision we make is designed to give you the best possible chance of success.
