For the longest time, women and married couples who experience infertility have been seeking ways on how to get pregnant. They search far and wide for alternative ways to have a baby, with no assurance that anything would work. But now, a new study showed a clearer picture in one of the alternative approaches for couples and women who want to bear a child. Let us take a look at the IVF success rates in Australia.
IVF success rates: A procedural overview
Since people started to take notice of how IVF works and how it helps couples to become pregnant, no concrete study or statistics showed how successful it could be. Blame it on a lot of factors – maternal age, quality of egg or sperm cell, the expertise of the fertility specialist, the laboratory, the process, and many more. These variables are all essential in the development of a healthy embryo, and some fertility experts, though they have researched and done their work well, just can’t seem to sometimes understand or explain why it fails.
In vitro fertilisation, or IVF, begins with a series of hormonal injections to prepare the woman’s body for ovulation. Once a woman is ovulating, egg retrieval is scheduled. Egg collection ideally happens the same time as the semen collection from the male partner so that fertilisation of the egg can commence immediately after. This is the fresh cycle where fertilisation of the first harvested eggs happens. Once fertilisation takes place, healthy embryos are separated, and one or more are implanted into the uterus. The number of embryos implanted may result in either more chances of getting pregnant or having twins or triplets, so discuss this step deeply with your fertility specialist.
If there are remaining healthy embryos available after the embryo transfer, you and your fertility specialist may opt to freeze these to be used in case the first attempt of becoming pregnant fails. This step saves you time and money to start over again.
IVF success rates: The numbers
According to the data taken from the Australian and New Zealand Assisted Reproductive Technology Database, about 33% of women who just started IVF became pregnant on their first try or cycle. Not only that, this result gives hope to other aspiring moms undergoing IVF because the IVF success rates showed a continued increase to up to 54% to 77% by the eighth cycle.
While most studies give information about IVF success rates during the step-by-step process (egg collection, fertilisation, or embryo transfer), this study showed the success rates of IVF per each cycle. It also showed the effect of maternal age on the success of the procedure.
For women who underwent IVF before turning 35, the chances of having IVF success rates the highest. The study highlighted that women under the age of 30 had a whopping 44% chance of having a successful pregnancy during their first cycle, with an increasing live birth rate of 69% to 91% after six tries or cycles. Women aged thirty-plus still get higher IVF success rates, just lower than younger mothers.
Meanwhile, advanced age also shows a significant effect on the IVF success rates. For hopeful mothers who underwent IVF aging from 40-44 years old, the study showed an 11% chance of getting pregnant during the first cycle, and 21% to 34% success after six cycles.
IVF success rates: What the study is for
This IVF success rates study aims to provide hope for women all over Australia about the possibility of having a baby using an alternative scientific approach that somehow guarantees success, depending on a number of variables. Studying this research will help women of all ages to make educated choices, with their fertility specialist, about whether to undergo IVF or any assisted reproductive treatment (ART) for that matter. Likewise, it allows couples who already started the IVF cycle to decide on whether they would push through with another cycle or switch to a different approach.
