Note:
- Your success rate can be affected by your age, weight and cause of infertility. Individual results will vary with individual circumstances.
- Not every treatment cycle will result in an egg retrieval, an embryo transfer or embryo / blastocyst vitrification.
- For more information about understanding how to interpret IVF success rates, you can refer to the Human Fertilisation and Embryology Authority (HFEA).
Success rates of complicated IVF cases
Many of the cases we treat are complicated, and our consistent success rates are a testament to our expertise in fertility treatment.
- 39.21% of our cycles are performed on women with low ovarian or egg reserves (between 2020 to 2022)
- 73% of our treatment cycles are performed on patients who are either low responders or aged 40 and above (between 2020 to 2022)
Optimising IVF success rates

We aim to increase the chances of IVF success by:
- Adopting and constantly familiarising ourselves with technologies and protocols while upholding stringent quality control and laboratory standards
- Attracting skilled and experienced fertility specialists into our team, and continuously improving our services for better clinical outcomes
- Partnering with experts in the assisted reproductive technology (ART) field, such as Dr Mashashige Kuwayama, the head of Tokyo-based Repro-support Medical Research Centre and the inventor of the renowned Cryotec/Cyrotop method.
Success rate of freezing embryos
Mount Elizabeth Fertility Centre has been vitrifying (freezing) embryos since 2007. This technique allows for even safer and more efficient vitrification of eggs and embryos at a 100% survival rate.
Advanced IVF technologies at Mount Elizabeth
The major advances in IVF technology include:
These methods have improved the number of live births in each stimulated IVF cycle, and have been routinely practised at Mount Elizabeth Fertility Centre since 2002.
