چکیده انگلیسی
A retrospective cohort study of 8736 autologous single vitrified-warmed blastocyst transfer cycles was conducted in a single centre to investigate the effect of cryostorage on clinical and neonatal outcomes. Cryostorage duration was classified into three groups: (A) 0-2 months (n = 4702); (B) 2-13 months (n = 2853) and (C) 13-97 months (n = 1181). Blastocysts were vitrified using the Cryotop method. No significant differences were observed in live birth rates: (A) 37.3%; (B) 34.9%; (C) (35.2%). Gestational period was significantly shorter in group C: (A) 38.7 ± 1.8; (B) 38.6 ± 1.6; (C) 38.1 ± 1.7; P < 0.05. This was clinically unimportant as the average gestational age was more than 38 weeks. No significant differences between groups were observed in birth weight: (A) 3060 ± 455âg; (B) 3052 ± 449âg; (C) 2992 ± 445âg, or congenital malformation rates: (A) 2.2%; (B) 1.9%; (C) 1.8%. The limitation of this study was that maximum storage duration was 8 years; most blastocysts were in cryostorage for much shorter periods. Long-term storage of blastocysts that are vitrified using an open device vitrification system has no negative effect on pregnancy and neonatal outcomes.
