Answer from: Raúl Olivares, MD
It’s quite a common question that patients ask me. It’s true that in most cases, the first cycle of IVF is going to be unsuccessful and that they may need to go for more than one round in the majority of the cases. This is something that is going to depend a lot on the age of the woman. If we are treating a young girl, let’s say 27- 28 with a tubal factor and everything else is okay, the success rate of the first transfer is going to be very high, probably more than 65%. The success rate of the first cycle could be even higher than 85%. That means that only 15% of these patients may need a second round of IVF.
On the other side if we are treating a patient who is 43 years old with a low variant reserve, unfortunately, in these cases, most of the cycles are going to be unsuccessful. The pregnancy rate of the first attempt can be as low as 5 or 6 %. This is an answer that should be given individually to each patient based on their own characteristics and on their own problems.
On average, for example, our pregnancy rate for people younger than 35 is over 65% in the first transfer. For people between 35 – 40, it’s going to be around 45 to 50%, for people who are over 40 and up to 42, it could be 35 to 38%. Over 42 is when the pregnancy rate decreases, and it comes to a 10-15%. Based on that, you can get an idea of how likely it’s going to be that you may need more than one round of IVF until you get your baby.
What is the average number of failed IVF cycles for various patients' age groups?
It has been shown that going through 3 full cycles of IVF increases the chances of pregnancy to 45-53%. What is the average number of IVF cycles before success? How many cycles are needed for a successful pregnancy?
