IVF Success Rates Have Improved in Last Decade in Older Women
The team of Medical Researchers at UNSW has released a new report as per their research study on IVF. According to their report, the IVF success rates have improved over the past 10 years especially in older women. The data shows significant changes in the ratio for those who are unable to conceive a baby naturally.
IVF, being the most advanced treatment has several drawbacks. Many people believe that the treatment is not worthy as the success ratio is lower than what the IVF centers are claiming. However, according to the researchers at UNSW, the treatment is nothing less than a blessing for older women.
What’s the latest research report says?
The new research report claims that the live birth rate per cycle has been increased by 18% for those women who have used their own eggs for conceiving. The study also suggests that the increased ratio has older women group in the majority.
Professor Georgina Chambers is a lead author at UNSW’s ANZARD. The professor has released a detailed report by comparing the initiated live birth through IVF on women who belong to different age groups. According to the report, “For example, in women aged 35–39, the live birth rate per cycle started has increased from 19 percent to 23 percent, representing a 20 percent relative increase in success rates.”
Furthermore, the report has also described the effects of IVF treatment on even an older group aged 40-44. In this particular age group, the research study claims that the success rates have been increased by 10%. This 10% success rate in this age group is representing a total of 27% increased rates in the last 10 years.
What is ANZARD?
ANZARD: Assisted Reproductive Technology in Australia and New Zealand.
ANZARD generates reports on various health-related subjects. The report is funded by Australia and New Zealand’s Fertility Society Foundation named the Fertility Society of Australia and New Zealand. The report surveys the IVF centers across these two countries.
Australia and New Zealand have a total of 94 IVF centers. The ANZARD’s latest report is based on these 94 IVF centers from both the countries i.e. Australia and New Zealand.
Comparison of Success Rates
The ANZARD’s report has listed the data of 2018 and 2019. We have the data of the most recent year i.e. 2019 through the report. The data shows that there were over 16,310 babies born in Australia and New Zealand through this treatment. The data is collected from all 94 IVF centers.
The report further claims that out of 16,310 babies born, the initiated IVF cycles were 88,929 in the year 2019. A 6.2% increased rate compared to the previous year i.e. 2018.
The initiated cycles are different from each other and for that reason, the research study may vary from team to team. Not all cycles can go for embryo transfer. However, the embryo transfer rates have also been increased significantly over the past 10 years.
If we talk about the data of previous years, the live birth rates through embryo transfer have been increased by 6%. In the year 2018, the live birth rates through embryo transfer were 22% which has now been increased to 28% in the year 2019.
Just like the previous years’ data, the success rates ratio was higher in younger women. The success ratio was 35.1% for the first cycle or we can say fresh cycles. The ratio for women aged 30-34 was 34.1%. For older women aged around 44, the live birth success rate was 1.7% for the initial cycle and 9.2% for the second cycle.
Different countries have adopted different techniques to give birth to their own babies. Frozen cycles are considered to be the most effective ones. The reports show that frozen cycles’ success rate is higher than the other cycles of twins and triplets.
The team of researchers has also compared the data between the frozen cycle embryo transfer and fresh cycle embryo transfer. The data shows over 50% increased rates over the past 10 years. So the process of transferring embryos through a frozen cycle is highly recommended by the researchers. The same technique is now being adopted by other IVF centers across the globe.
Key Stats from the Report
- Single embryo transfer rates have been increased compared to the previous year.
- Multiple live birth rates have been decreased through the frozen cycle technique over the past 10 years.
- The live birth rates have been increased by 6% in Australia and 2% in New Zealand
With new technologies and inventions, the success rate of IVF will be increased further in the coming years. Researchers are doing their best to bring new techniques so that they can help those who can’t conceive a baby naturally.
