Preimplantation Genetic Testing for Aneuploidy (PGT-A)

Helping you have a successful pregnancy and a healthy baby by selecting chromosomally normal embryos



It's very important to identify embryos with the correct number 
of chromosomes for successful fertility treatment.

PGT-A is a genetic study of the embryo produced during IVF treatment and can help you have a healthy baby. The PGT-A test:

  • Is performed on the embryo before it is transferred.
  • Allows for the identification and transfer of embryos free from aneuploidies.
  • Significantly increases pregnancy rates per transfer.
  • Reduces the time needed to achieve pregnancy.
Who should use PGT-A testing?

Who should use PGT-A testing?

PGT-A is especially recommended for:

  • ADVANCED MATERNAL AGE: 35 years and above.
  • RECURRENT MISCARRIAGES: women with two or more miscarriages.
  • IVF failures: two or more IVF failures .
  • MALE FACTOR: considering a low quantity and/or quality of sperm.


  • Reduced miscarriage rates.
  • Higher pregnancy rates per transfer.
  • Fewer cycles of IVF treatment needed (less time and money).
  • Greater chance of having a healthy child.
  • Fewer wasted transfers (implantation failure).

Optional Single Embryo Transfer (SET)

Multiple pregnancies after an IVF treatment were usual, as clinicians transferred two or more embryos in an attempt to maximize the chances of implantation.

However, multiple pregnancy has increased risks for the mother and the babies:

  • Hypertensive disorders of pregnancy
  • Cord prolapse
  • Malpresentation
  • Premature rupture of membrane
  • Low Apgar scores
  • Cesarean section rate
  • Perinatal death

Twin pregnancy is associated with more pregnancy complications and poorer pregnancy outcome than singleton pregnancy.

The development of the IVF techniques and recent studies demonstrate no statistical difference in pregnancy achieved by Single Embryo Transfer and a reduction in multiple gestations.
