There are two tendencies. Some professionals say since we can detect abnormal embryos in all ages, even in young patients, even though the percentage is not very high, it can be 20%, let’s do PGT-A to all patients. On the other hand, we have another group of professionals that don’t see an advantage in doing that, and they decide to offer PGT-A only for a specific group of patients.
According to published data, PGT-A is improving the outcomes mainly in patients over 35 years old. In young patients, including egg donors, if there is no other factor like a severe factor, published data didn’t show any improvement in the results. In my opinion, there are different policies, different tendencies, but I would recommend PGT-A only to specific groups that we know are at higher risk to see the benefit of this test.
