Clinics in and outside of Australia would always advertise that their IVF success rates are competitive and reliable.  But how are IVF success rates measured? What are the factors that affect its success rate?

 

What are IVF success rates?

The success rates of IVF are actually the number of positive pregnancies after the IVF procedure. The two main variables needed to compute a clinic’s success rate using IVF are the number of pregnancies or live births and the number of attempts or procedures performed.

In Australia, news about the increase of IVF procedure demand in the country and in New Zealand show favorable success rates as well. In a September 2018 report by The Spring Morning Herald, there are approximately 13,500 babies born through IVF from 2016 to 2017. Their sources even claimed that one in every 25 children in Australia is now an IVF baby.

 

How are IVF success rates determined?

The IVF success rates will all depend on how clinics calculate their practice’s success rates to make them look competent and dependable. One way is to compute the clinical pregnancy rate, and the other is to compute the live birth rate.

Clinical pregnancy rate is determined by dividing the number of positive pregnancy tests over the number of attempts or procedures (per cycle or egg transfer). This way of calculating the IVF success rate is the most common process that clinics use whenever they publish their practice’s success reputation. Why? Because the result of a pregnancy test is much faster to get than to wait for a patient to give birth. Most IVF clinics rely on this type of computation to quickly inform their patients of the high success rate of their practice with regard to the number of pregnancies they achieved after IVF.

Live birth rate, on the other hand, calculates the number of safe deliveries of healthy babies after the IVF procedure. This type of computation is what most couples want to know when choosing the IVF clinic to trust. They know that even if you already have a positive pregnancy test, the possibility of having a baby is still undetermined. There are still many things that can happen during the nine months of pregnancy. So they are more concerned about this success rate determination than just the clinical pregnancy rate.

 

What factors affect the IVF success rates?

The success of having a baby after this ART procedure depends on many variables, but the main element is maternal age. This factor is by far the most critical ingredient in the IVF procedure. A woman’s age directly affects the success of the fertility process, as shown in the results gathered by different IVF agencies including the UNSW’s National Perinatal Epidemiology and Statistics Unit (NPESU). As you grow older, the possibility of getting pregnant through IVF slims down as well.

Other factors that may affect the IVF success rates are the type of fertility problem a couple has, the woman’s pregnancy history, the expertise of the fertility specialist and laboratory, and the patient’s lifestyle.

 

There are so many real-life success stories you may watch or read about the IVF procedure. It shows how IVF can still help couples build their family. It is only fair to know how your trusted IVF clinic and specialist determine their IVF success rates because we also have to accept the fact that going through this journey may still be full of uncertainty up to the very end.
