ABSTRACT
Objective: To evaluate pregnancy outcomes in patients with frozen blastocyst embryo transfer
cultured using the Timelapse system with and without PGT-A at Hanoi Obstetrics and Gynecology
Hospital.
Materials and methods: This cross-sectional descriptive study was conducted on 221
patients who underwent single day-5 frozen embryo transfer using the Timelapse system at Hanoi
Obstetrics and Gynecology Hospital, from June 2023 to May 2024.
Results: The rate of β-HCG (+), clinical pregnancy rate, and progressive pregnancy in the
non-PGT group and the group with normal PGT results were significantly higher than in the
group with abnormal PGT results (p < 0.05). The difference between the 3 groups was not
statistically significant (p > 0.05). The pregnancy rate in ICM type A (70%; 53.9%; 71.4%) was
higher than that in type B (30%; 46.1%; 28.6%) and type C (0%; 0%; 0%) in all 3 groups: no
PGT, normal PGT and abnormal PGT. The pregnancy rate in TE type A (61.4%) was higher than
that in type B (38.6%) and type C (0%) in the group that did not do PGT. The pregnancy rate
in TE type B (55.3%; 71.4%) was higher than that in type A (36.8%; 28.6%) and type C (7.9%;
0%) in both groups that did PGT with normal results and abnormal PGT.
Conclusions: Pregnancy outcomes in patients undergoing day-5 frozen embryo transfer
cultured using the Timelapse system without PGT-A or with normal PGT-A results are superior
to those with abnormal PGT-A results (p > 0.05).
Keywords: Frozen, blastocyst embryo, Timelapse incubator, PGT-A.
