The preimplantation genetic testing debate continues: first the hype, then the tension, now the hypertension?
The study by Zhang and colleagues (1) in this month’s Fertility and Sterility asks an important question: Is preimplantation genetic testing (PGT) associated with an increased risk of obstetric complications? Given the physiologic role of the trophectoderm in implantation, invasion, and placentation (2), it seems biologically plausible that manipulation of these cells through biopsy sampling could result in an increased risk of aberrant placentation. The rapid increase in the clinical use of PGT further justifies more scientific inquiry into this question.
