If you’re considering IVF, one of the most common questions is ‘What are my chances of success?’. But while success rates can provide helpful insight, it’s important to recognise their limitations and to take personal circumstances into account when exploring treatment options.
There are a wide range of personal and medical factors that can influence your individual outcome. Understanding what affects your chances of success can help you to make informed decisions and set realistic expectations.
Here’s a closer look at some of the key factors that play a role:
1. Age
Age is one of the most significant predictors of IVF success. As women age, both the quality and quantity of your eggs naturally decline. IVF tends to have higher success rates for women under 35. After 40, the chances of success using your own eggs decrease significantly – though successful outcomes are still possible, especially with donor eggs.
2. Cause of Infertility
The underlying reason for infertility can impact how well IVF works. Some conditions may respond better to treatment, while others may pose more significant challenges.
3. Embryo Quality
The quality of embryos used in IVF plays a major role in whether implantation and pregnancy occur. Embryologists assess embryos based on their development and appearance, and in some cases, preimplantation genetic testing (PGT-A) is used to screen for chromosomal abnormalities.
4. Ovarian Reserve
Ovarian reserve refers to the number of viable eggs remaining in the ovaries. It’s assessed through measuring hormone levels like Anti-Müllerian Hormone (AMH) and performing tests such as antral follicle count (AFC). A higher ovarian reserve often leads to more eggs retrieved during stimulation, which can improve the chances of success.
5. Lifestyle Factors
Everyday habits can make a difference. Smoking, excessive alcohol consumption, recreational drug use, and even high levels of stress can negatively affect fertility. Body weight also plays a role – both underweight and overweight individuals may experience reduced IVF success rates.
6. Uterine and Endometrial Health
A healthy uterine environment is crucial for implantation. Conditions like fibroids, polyps, scar tissue, or a thin endometrial lining can make it harder for an embryo to implant and develop.
7. Sperm Quality
Male fertility is equally important. Factors such as low sperm count, poor motility, or abnormal morphology can affect fertilisation. In cases of male factor infertility, ICSI (intracytoplasmic sperm injection) is often used to increase the likelihood of success.
8. Number of IVF Cycles
Sometimes, it takes more than one attempt. Many patients are successful after two or more IVF cycles, as each cycle offers an opportunity to adjust protocols and to learn from previous outcomes.
9. Fresh vs. Frozen Embryo Transfers
Both fresh and frozen embryo transfers have their advantages, depending on individual circumstances. In some cases, frozen transfers can result in higher success rates, especially when timed to optimise endometrial receptivity.
Conclusion
IVF success rates are just one part of the puzzle. They can give you a general idea of what to expect, but they don’t tell the whole story. That’s why it’s so important to consult with a fertility specialist who understands your unique situation, explores your options, and guides you every step of the way.
