【摘要】：目的:比較分析玻璃化和程序化冷凍卵裂期和囊胚期胚胎保存后復(fù)蘇效果及臨床結(jié)局。方法:根據(jù)不同冷凍保存時間將胚胎凍融周期分為4組,分別為1~6個月組、7~12個月組、13~24個月組和≥25個月組,比較四組的復(fù)蘇率、臨床妊娠率和流產(chǎn)率。根據(jù)不同冷凍保存方法分為玻璃化冷凍組和程序化冷凍組。結(jié)果:4組胚胎復(fù)蘇存活率(98.1%、99.0%、96.8%和95.7%)、臨床妊娠率(54.4%、55.4%、49.6%和51.5%)和流產(chǎn)率(10.7%、8.9%、9.45和11.15)相比較,差異均無統(tǒng)計學(xué)意義(P0.05)。玻璃化冷凍組胚胎復(fù)蘇率和臨床妊娠率均顯著高于程序化冷凍組(P0.05)。結(jié)論:胚胎冷凍保存時間不影響解凍后胚胎質(zhì)量。玻璃化冷凍胚胎方法復(fù)蘇效果優(yōu)于程序化冷凍法。囊胚期凍融胚胎可獲得較高的臨床妊娠率。
[Abstract]:Objective: to compare and analyze the effect and clinical outcome of embryo resuscitation after cryopreservation of vitrification and programmed cryopreservation. Methods: the embryos were divided into 4 groups according to the freezing and thawing periods. The resuscitation rates of the four groups were compared, which were 1 ~ 6 months group, 7 ~ 12 months group, 13 ~ 24 months group and 鈮，
