Answer from: Raúl Olivares, MD
That depends a lot on the indications for IVF. As you can imagine, it’s not going to be the same. If you’re starting IVF at 29, and you have a tube problem, the chances of success are going to be extremely high on the first attempt. If you are 43, and you had 5 miscarriages and, we would think that there is going to be a problem with the egg quality or your ovarian reserve, it could be hard to get a good number of eggs and a good number of embryos to obtain that healthy embryo that can become a baby.
What I can tell you is that we usually think that in most cases, when a patient hasn’t been successful after 3 rounds of IVF, which means there were 3 egg collections plus frozen transfers that you may have in between, we really feel that IVF is not going to solve the problem. If it does, it is going to be a very low percentage of cases. It’s also common that between different IVF, you may carry out some tests to see if there is any implantation issue or any genetic issue or things like that.
After 3 rounds of IVF, if you haven’t got an ongoing pregnancy, it is probably time to consider important changes, mainly related to changing the gametes, etc.
What is the average number of rounds of IVF per couple? Is there any cut-off point?
Nowadays, it is quite common that, on average, a couple requires more than 1 IVF cycles to get a baby. There are lots of factors that can influence the outcomes, we always need to consider the modifiable factors like lifestyle and unmodifiable such as maternal or paternal age. That is why detailed individualized assessment and treatment is the key before starting your journey. On average, how many IVF cycles do I need to get a baby? How many times can I do IVF in a year? How soon after failed IVF can I try again? Is there a limit to the number of IVF treatments?
