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 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 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 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.
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.
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.
