• Abnormal number of chromosomes (Aneuploidy). 
• Specific single gene disorders such as Cystic Fibrosis, Muscular Dystrophy, Thalassemia. 
• Embryos with abnormal chromosome structures, such as when a parent is known to have chromosome translocation or inversion, which can cause recurrent pregnancy loss.

• Women over age 35.
• Women at any age that have failed multiple IVF cycles. 
• Women that have had recurrent pregnancy loss.
• Women or partners who are known to have chromosome translocation or inversions.
• Women who want to select sex of the embryo and balance their family.

The cells that are biopsied during PGT are cells that will develop into future placenta. The inner cell mass that will develop into the fetus remains intact during the PGT process. Only 5-6 cells are removed for genetic testing and PGT is considered a safe technology. That being said, there is a very small chance that removing a cell from the embryo could damage the embryo. Think Fertility has a team of embryologists who have extensive experience and high skills of embryo biopsy. The chance of embryo damage from biopsy and PGT is < 1 %.

Yes. The sex of embryos can be identified by PGT and only the healthy embryos of the desired sex will be transferred.
