Who might be recommended to have PGT-A?
Older women are more likely to have eggs with the wrong number of chromosomes, so traditionally it’s been offered to women over 37. Abnormal chromosomes are thought to be the main reason why older women have difficulties conceiving and are more likely to have a miscarriage or a baby with Down’s Syndrome.
Your doctor may also recommend PGT-A if you have a family history of chromosome problems, if your sperm is at risk of carrying abnormal chromosomes, or if you’ve had several miscarriages or failed IVF attempts without explanation.
However, there is limited evidence to show that PGT-A benefits these groups (see more below). It’s also not a guaranteed way to prevent miscarriage or to have a baby.
