Does elevated basal follicle-stimulating hormone (fsh) at in vitro fertilization (ivf) cycle start impact euploid embryo rates across all ages?

Elevated basal FSH levels have long been associated with poor outcomes in fresh IVF cycles. There has been a shift toward pre-implantation genetic testing for aneuploidy (PGT-A) and freeze-all cycles, wherein the role of high FSH at cycle start is unclear.
