- Abstract
This study investigated whether singleton pregnancies conceived after preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) are associated with a higher risk of adverse perinatal outcomes than singleton pregnancies conceived after intracytoplasmic sperm injection (ICSI). We collected data on singleton live births after PGT-SR (n = 107) and ICSI (n = 585) in our hospital from January 2017 to August 2020. Multivariable analyses were used to adjust for maternal age, body mass index, gravidity and parity, paternal age, ovulatory disorder, and recurrent spontaneous abortion. The unadjusted results showed a significantly higher risk of hypertensive disorders of pregnancy (HDP) (odds ratio (OR) = 2.47; 95% confidence interval (CI): 1.10–5.54; P = 0.029) associated with PGT-SR singleton pregnancies than with ICSI singleton pregnancies. However, after adjusting for potential confounders, there were no longer any significant differences in the risk of HDP (adjusted OR = 2.24; 95% CI: 0.92–5.48; P = 0.077) between PGT-SR and ICSI singleton pregnancies. There were no significant differences between PGT-SR and ICSI singleton pregnancies in terms of gestational diabetes, preterm premature rupture of membranes, placenta previa, cesarean delivery, gestational age (weeks), preterm delivery (< 37 weeks), very preterm delivery (≥ 28 weeks and < 32 weeks), birth weight (g), low birth weight (< 2500 g), very low birth weight (< 1500 g), birth height (cm), birth defects, and 1-min and 5-min Apgar scores. In conclusion, for single frozen-thawed blastocyst cycles, there were no significant differences in adverse perinatal outcomes between PGT-SR and ICSI singleton pregnancies. However, due to the limited sample size, these conclusions need to be confirmed by further studies.
