Background and Aims: Sometimes the preimplantation genetic testing for aneuploidy (PGTA) results return with "no result" (NR) even though the percentage of this type of result is quite small. Our desire was to rebiopsy these embryos and reanalysis, then determining whether it is efficient to ...

Embryos were vitrified. 42 couples had their blastocysts vitrified on Day 5/6 without testing. LAH was introduced to all patients in October 2021. Before that, no LAH was performed. Embryos were transferred to patients 2 hours post-warming after LAH. Pregnancy test was performed 10 days after...
