Many have built their family with the help of an egg donor, and if you are considering using a donor egg, it can feel a little overwhelming. You may also be wondering how successful the process is. After all, having the best possible chance of conceiving is essential. This is where understanding success rates can help you decide the right pathway for you.
IVF success rates are defined as the percentage of IVF treatments that result in either a pregnancy or live birth.
It is important to note, however, that the number of embryos transferred doesn’t always correlate directly with the number of pregnancies or live births, as not every embryo transfer guarantees a successful outcome.
Several factors can influence the likelihood of conception:
Age – As women age, particularly those over 35, the chances of conceiving decrease. This decline is due to a reduction in both the quality and quantity of eggs, which lowers the likelihood of a successful pregnancy.
Embryo quality - Higher-quality embryos are more likely to implant in the uterus, which increases the chances of a successful pregnancy through IVF treatment. Embryo quality is assessed using an EmbryoScope™, an incubator with built-in cameras that monitors the embryo’s growth.
Lifestyle choices - Maintaining a balanced and healthy diet, rich in fruits, vegetables, vitamins, and nutrients, supports fertility health. Incorporating regular exercise into your routine can improve the quality of eggs and sperm development as well. Conversely, limiting smoking and excessive alcohol consumption is advised, as this can negatively impact egg and sperm development.
Fresh or frozen embryo transfer – In general, frozen embryo transfers have a higher success rate compared to fresh embryo transfers. This difference can be attributed to various factors, including hormonal levels. However, it is essential to note that fresh cycles can also be effective for certain individuals, as success depends on multiple factors, including age, medical conditions and personal circumstances.
Using donor eggs for IVF treatments can improve the chances of success compared to using a woman’s own eggs. Eggs from younger individuals tend to be healthier and of better quality, which increases the likelihood of fertilisation and implantation. Therefore, older patients, as well as those with a low ovarian reserve, would particularly benefit from using donor eggs. However, it's important to understand that using donor eggs does not guarantee success; other factors, such as underlying health conditions, also need to be taken into account.
We have strict criteria for egg donors, ensuring they are healthy and have a good ovarian reserve to provide the highest quality for patients using donated eggs.
Data from the UK’s regulatory authority for fertility treatments, the HFEA, shows that across all age groups, using donor eggs provides about 1 in 3 chance of live birth for every embryo transferred. In contrast, the chance of women aged 43-50 using their own eggs is approximately 1 in 20.
At TFP Fertility clinic, our experienced medical team works hard to ensure the best possible outcomes, which is why our success rates exceed the national average. If you are considering using egg donation for IVF and are over 30, the chances of success with patients’ own eggs vs donor eggs are as follows:
33% vs 34% for people aged 18-34
26% vs 34% for people aged 35-37
20% vs 32% for people aged 38-39
For those who are over 40, the chances of success with patients’ own eggs vs donor eggs are as follows:
12% vs 34% for people aged 40-42
5% vs 35% for people aged 43-44
4% vs 30% for people aged 45-50
Please note that the success rates are measured as live births per embryo transferred. If you have any concerns, contact your local TFP Fertility clinic. We will provide you with the advice and guidance you need.
