Access Advanced IVF Treatment Facilities in Singapore
As a patient with Virtus Fertility Centre Singapore, you will have access to the region’s experienced IVF and fertility specialists, as well as pioneering fertility specialists and embryolgists from the world’s most successful fertility Group, Virtus Health.
Every couple’s situation is unique, and at your initial consultation, your fertility specialist will give you an indication of your likelihood of conceiving. However, assisted conception nowadays provides the highest possible chance of starting a family, as the success of assisted reproductive technology has overtaken natural conception.
What is My Chance of Falling Pregnant with IVF?
When it comes to IVF, there is no agreed standard for reporting 'success'. Sometimes, IVF success rates are quoted per completed IVF treatment cycle - a complete IVF collection and treatment cycle can involve multiple transfers of embryos collected from one egg collection. Success rates measured this way will therefore naturally be higher than success rates measured per embryo transfer.
At Virtus Fertility Centre Singapore, we most often measure IVF success rates as clinical pregnancy (a pregnancy confirmed by a blood test and ultrasound scan, usually at around 6-8 weeks) per embryo transfer. Sadly, not every pregnancy will carry to a live birth, so we also measure live births per embryo transfer. We report our success rates per embryo transfer as we want to give you the most realistic understanding of your chance of success following each individual embryo transfer.
However, it is important to understand that not every treatment cycle will result in an embryo transfer. For some women, no egg will be collected and sometimes after the eggs have been collected, there may be no transfer because embryos have not developed.It is therefore important to understand what part of the IVF treatment cycle a statistic is measuring. Even after checking on this, there are factors that need to be understood before you attempt to compare IVF success rates. For example:
- The most important factor determining IVF success rates is a woman’s age: When comparing IVF success rates, check that you are comparing rates for women of the same age. If ‘whole of clinic’ rates are quoted, consider whether the clinic might, overall, have older or younger clients than average – or do they perhaps send their more difficult cases to a different centre altogether?
- Ask how often a clinic transfers more than one embryo with each transfer: More embryos per transfer may make success rates appear higher, but Virtus Fertility Centre Singaporemostly performs single embryo transfers, as multiple embryo transfers can also increase the risks of multiple births, low birthweight and premature births.
- Check whether the data includes processes like ICSI, frozen embryo transfers or only ‘fresh’ embryo transfers.
Virtus Fertility Centre Singapore is part of one of the world's largest fertility groups.
To optimise the chances of a successful pregnancy after embryo transfer, Virtus Fertility Centre has an elective 'freeze all' approach which involves freezing all embryos to be used later in a natural cycle, or in a cycle with hormonal replacement to prime the endometrium. Our 'freeze-all' approach to treatment has shown good pregnancy outcomes in all age groups.
The majority of IVF cycles performed at Virtus Fertility Centre Singapore are frozen embryo transfers. The following tables shows the clinical pregnancy rate per egg retrieval (OPU) resulting in a frozen transfer and live birth rates in 2022 and ongoing pregnancy rates in 2023 across six age groups at Virtus Fertility Centre Singapore.
This information also excludes donor gametes, PGT embryos and embryos created in other IVF centres.

There are a number of factors that may affect success rates including but not limited to; age, weight, cause of infertility, and individual results will vary with individual circumstances.
