IVF-ET治疗中短时受精对治疗结局的影响
目的比较分析IVF-ET周期中短时受精对受精、胚胎质量和妊娠结局的影响,明确短时受精在IVF-ET周期中的实施必要性.方法回顾性分析2013年10月至2014年1月就诊于昆明医科大学第二附属医院生殖医学科的392例IVF受精正常患者资料.患者平均年龄(32.39±4.71)岁,共获卵5 696枚,每个患者的卵随机分为短时受精组(A组)和过夜受精组(B组),A组卵子2 643枚,B组卵子3 053枚.分析2组正常受精率、成熟卵率、1PN率、3PN受精率、卵裂率、优质胚胎发育率、新鲜胚胎移植周期胚胎着床率和全胚冷冻周期行FET后妊娠率和胚胎着床率.结果分析2组之间成熟卵率、正常受精2PN率、1PN...

Summary: | 目的比较分析IVF-ET周期中短时受精对受精、胚胎质量和妊娠结局的影响,明确短时受精在IVF-ET周期中的实施必要性.方法回顾性分析2013年10月至2014年1月就诊于昆明医科大学第二附属医院生殖医学科的392例IVF受精正常患者资料.患者平均年龄(32.39±4.71)岁,共获卵5 696枚,每个患者的卵随机分为短时受精组(A组)和过夜受精组(B组),A组卵子2 643枚,B组卵子3 053枚.分析2组正常受精率、成熟卵率、1PN率、3PN受精率、卵裂率、优质胚胎发育率、新鲜胚胎移植周期胚胎着床率和全胚冷冻周期行FET后妊娠率和胚胎着床率.结果分析2组之间成熟卵率、正常受精2PN率、1PN率、3PN率、卵裂率、优质胚胎率、新鲜胚胎移植周期妊娠率、胚胎着床率、全胚冷冻周期首次行FET后妊娠率和胚胎着床率,A组分别为88.84%、63.42%、2.88%、6.08%、98.56%、46.85%、44.57%、23.41%、49.06%和25.20%;B组分别为90.04%、65.56%、1.86%、5.87%、98.65%、42.49%、43.21%、23.23%、53.33%和33.33%.2组之间卵子成熟率、正常受精率、卵裂率、3PN率、新鲜胚胎移植周期妊娠率、胚胎着床率、全胚冷冻周期首次行FET后妊娠率和胚胎着床率差异无统计学意义(P〉0.05),但短时受精组1PN率、优质胚胎率高于过夜受精组差异有统计学意义(P〈0.05);新鲜周期和FET临床妊娠率和胚胎着床率差异有统计学意义(P〈0.05).结论在IVF-ET的实施过程中,根据患者的病史,部分卵子选择短时受精-早期补救对于避免完全受精失败或者低受精率的发生具有一定的意义.短时受精增加异常受精率,妊娠率与过夜受精无差异.由于样本量的限制,此结果仍需要进一步的验证. |
