When is PGT Right for You? Key Considerations

Preimplantation genetic testing (PGT) screens embryos for chromosomal abnormalities, helping reduce miscarriages and improve IVF success rates. It’s recommended for women over 35, those with a family history of chromosomal issues, or a history of recurrent miscarriages. PGT identifies conditions like Down syndrome and Turner syndrome, with a process involving IVF, cell biopsy, and chromosome analysis.

Key Takeaways

PGT for High-Risk Candidates: Age and Medical History Factors

PGT is especially recommended for women over 35, individuals with a family history of chromosomal abnormalities, or those experiencing recurrent miscarriages or multiple failed IVF cycles. Advanced maternal age increases aneuploidy risk, making chromosomal screening critical for improving implantation success.

Understanding What PGT Screens for: Chromosomal Abnormalities

PGT tests for chromosomal duplications (e.g., Down syndrome), deletions, sex-chromosome abnormalities (e.g., Klinefelter Syndrome), and gender. This comprehensive analysis helps identify embryos with abnormal chromosome counts, which are the leading cause of implantation failure.

Benefits of PGT: Improved IVF Success and Reduced Miscarriage Risk

PGT minimizes the transfer of aneuploid embryos, reducing miscarriage rates by up to 50% and increasing live birth rates. Studies show embryo implantation success improves significantly when chromosomally normal embryos are selected.

PGT Process Overview: From IVF to Chromosome Analysis

The PGT process involves standard IVF, embryo cultivation until the blastocyst stage, trophectoderm cell biopsy, and next-generation sequencing to analyze chromosomal integrity. Results guide embryo selection for transfer.

PGT and Gender Identification: Selecting Embryo Sex for Medical Reasons

While PGT can determine embryo sex, this feature is primarily used for medical indications (e.g., preventing sex-linked genetic disorders), not for non-medical gender selection. Ethical guidelines strictly govern its application.
