Question: My husband & I had tried conceiving through IVF but did not succeed. If we try IVF again, would my chances of getting pregnant lower than others? How do I increase my chance of success?
Dr Helena’s answer: The advent of IVF had greatly revolutionize the world of reproductive medicine. Millions of babies had been born, as the result of IVF. Without IVF, the birth of these babies would not had been possible due to various infertility issues
However, is IVF a magic bullet with 100% of pregnancy success rates?
The answer is no, as we know, IVF’s success rate is not 100%.
A few important factors associated with success rates of IVF is women’s age, the duration of Subfertility and whether there is any previous history of pregnancies. Some other factors includes the quality and quantity of eggs, sperm quality & lifestyle and habits
For couples who didn’t succeed in getting pregnant during their first round of IVF, it is logically to wonder, whether they will ever get pregnant in their subsequent cycles of IVF
Generally the overall success rates of ONE IVF for a woman who is under the age of 35 is around 60-70%. We also know for a fact that a frozen embryo transfer has a higher pregnancy rate compares to a fresh embryo transfer. For most women under 35, there is a good chance that she produces more than 2 good quality embryos each IVF cycle. most of the time, these excessive embryos can be frozen and can be used in the future. Technically speaking, ONE IVF cycle can potentially resulting more than one pregnancy, if the woman has lots of embryos and keep coming back to get them transfer into her uterus.
Coming back to the question, we know for sure that if you have a good number of embryos from the result of ONE IVF, the chance of you getting pregnant with the subsequent Frozen embryo transfer is extremely likely, especially if you are under the age of 35
However, if you have no embryos frozen, what is your option?
This chart below showed a cumulative live IVF births from a study conducted.
This study looked at all the women under the age of 42, who are going through IVF.
The study revealed that the pregnancy rate is around 40% in this group of women after they completed their first cycle of IVF. For those women who did not get pregnant the first round and went on having the second round of IVF, there were another 20% who got pregnant after the second round. Therefore, by the 4th IVF cycle, around 80% of women would have achieved a live birth.
This statistic clearly shows that if you persevere and keep moving on, chances of you getting pregnant by the end of the 4th IVF is around 80%.
Therefore, it is not unusual for Fertility doctors to encourage our patients to keep moving on because the statistics had clearly show us the evidence.
To improve your chance of pregnancy for the next IVF, it is important to improve the quality of your eggs and sperms by eating healthy and improve lifestyle, quit habits which can potentially jeopardize your success rates such as smoking, alcohol and stress. Speak to your fertility doctor about what are the other options in your IVF treatment.
