目的 比较同一控制性超促排卵(COH)治疗周期中，体内成熟与改良技术体外培养成熟(IVM)的卵母细胞的早期胚胎发育能力及临床结局，探讨补充褪黑素的IVM技术在临床中的应用。方法 收集159例患者在COH周期中的920个成熟卵母细胞进行常规体外受精(IVF/ICSI)处理，同时收集同周期中1 283个未成熟卵母细胞，在添加褪黑素的改良IVM培养基中培养成熟后行ICSI处理。通过回顾性分析，比较常规助孕技术与改良IVM技术这两种方式，对辅助生殖治疗的助孕结局和妊娠结局的影响。结果 与从COH周期中收集到的行常规IVF/ICSI处理的成熟卵母细胞相比，经改良IVM技术促成熟的卵母细胞的优质囊胚形成率较低。但经胚胎移植后，两种方式获得的成熟卵母细胞的临床结局包括临床妊娠率、足月产率、婴儿体长、新生儿Ap-gar 评分，差异均无统计学意义。结论 IVM可以提高从COH周期中回收的未成熟卵母细胞的卵子利用率，改善辅助生殖技术助孕患者的妊娠结局。
Application of melatonin-supplemented in vitro maturation technology for human oocytes during COH cycle
Objective To compare the early embryonic developmental potential and clinical outcomes of oocytes matured in vivo and those matured by modified in vitro maturation(LVM)technology during the same controlled ovarian hyperstimulation(COH)cycle,and to explore the clinical application of melatonin-supplemented IVM technology.Methods 159 patients were recruited into the study.920 mature oocytes were collected during their COH cycles processed for conventional IVF/ICSI protocols,while 1 283 immature oocytes from the same cycles were matured in a melatonin-supplemented IVM medium before ICSI was performed.A retrospective analysis was conducted to compare the impact of conventional assisted reproductive technology and improved IVM technology on the outcomes of assisted reproductive therapy and pregnancy outcomes.Results Compared with mature oocytes collected from COH cycles treated with conventional IVF/ICSI,oocytes promoted by improved melatonin-supple-mented IVM technology had a lower rate of high-quality blastocyst formation.However,after embryo transfer,there was no significant difference in the clinical outcomes of mature oocytes obtained through two methods,including clinical pregnancy rate,full-term birth rate,neonatal length,and neonatal Apgar score.Conclusion The applica-tion of melatonin-supplemented IVM significantly increases the utilization of immature oocytes collected from COH cycles,improving the pregnancy outcomes of patients assisted by assisted reproductive technology.
