outcome in terms of implantation rate and its relation to the
number of visible mononucleate blastomeres(MNBs),the
degree of fragmentation,and equality of blastomeres.In—
tervention(s):Li ght microscopic evaluation of preembryos
before transfer on day 2.Main Outeome Measure(s):Im-
plantation rate. Result(s):The number of MNBs was
found to be related to implantation,whereas blastomere e
quality and rate of embryo fragmentation were not. The
implantation rate was statistically significantly higher in
cycles where a four cell preembryo with four MNBs was
transferred than after transfer of a four—celI preembryo with
zero to three MNBs(42% versus 22%).In a logistic re—
gression analysis. nucleation of all blastomeres was the
only morphologic parameter that was associated with the
implantation rate.℃onclusion(s):Evaluation of nuclear
status of four—cell preembryos is important in predicting
implantation potentia1. Visual【ization of four MNBs in a
four—cell preembryo predicted a statistically significant
hi【小er implantation rate than in cases where not all four
blast0meres were mononuc】eate.
体外受精治疗周期中四细胞前胚胎的核状态预测
着床能力
目的:评估单胚移植(SET)中常规筛查第2天四细
胞前胚胎核状态预测着床能力的价值。设计 :回顾性分
析。机构:私人体外受精(IVF)中心。患者:2002年 1月
至 2004年 11月间第 2天或第 3天胚胎移植前的新鲜
受精卵 1985例 ,其中 1295例(65.2%)为 SET。根据着
床率、可见单核卵裂球(MNBs)数 目、断裂程度及卵裂球
均匀程度回顾性
所有 SET周期 (n=861)第 2天
移植前的四细胞前胚胎。干预:光镜下评估第 2天胚胎
移植前的前胚胎状况。主要观察指标:着床率。结果:
MNBs数 目与着床率相关,但与卵裂球均匀程度及胚胎
断裂率无关。具有 4个 MNBs的四细胞前胚胎其着床率
显著高于具有 0~3个 MNBs的四细胞前胚胎 (42% 傩
22%)。logistic回归分析提示卵裂球的成核现象是与着
床率相关的唯一形态学参数。结论:评估四细胞前胚胎
的核状态是预测着床能力的重要因素。具有 4个 MNBs
的四细胞前胚胎其着床率显著高于无 4个 MNBs的四
细胞前胚胎。

nadotropins followed by IVF as treatment
for primary infertility: A cost-based deci-

States]一FERTIL.STERIL.2005.84/3(600—604)
Objective:To compare the economic consequences of pro-
ceeding directly to IVF to those of proceeding with go—
nadotropins followed by IVF in patients<35 years of age
with unexplained infertility. Design: A decision-tree-
mode1. Th e model incorporated the cost and SUCCESS of
each infertility regimen as well as the pregnancy associated
costs of singleton or multiple gestations and the risk and
cost of cerebral palsy.Main Outcome Measure(s):Cost
per live birth.Resuh(s):Both treatment arnls resulted in
a> 80% chance of birth.The gonadotropin arIn was over
four times more likely to result in a high—order multiple
pregnancy (HOMP).Despite this,when the base case
estimates were utilized.immediate IVF emerged a8 more
costly per live birth.In sensitivity analysis,immediate IVF
became less costly per live birth when IVF was more likely
to achieve birth(55.1%)or cheaper($1 1,432)than our
base case assumptions.Conclusion(s):After considering
the risk and cost of HOMP,immediate IVF is more costly
per live birth than a trial of gonadotropins prior to IVF.
基于体外受精 (IVF)及促性腺激素结合 IVF治疗
原发性不孕症医疗成本的决策分析
目的:比较年龄 <35岁不明原因不孕症患者直接
体外受精(IVF)与应用促性腺激素类药物后再行 IVF两
种
的医疗成本差别。设计:设计一种决策树模型。该
模型综合分析每种不孕症治疗方案的医疗成本;妊娠成
功率、单胎或多胎妊娠相关的医疗成本、脑瘫发生风险
及相关医疗成本。主要观察指标:每例单活胎所需医疗
成本。结果:两种治疗方案的活产率均 >80%。注射促
性腺激素组导致多胎妊娠 (HOMP)的发生率高于直接
IVF组 4倍多。尽管如此,与制定的基本医疗成本比较
后发现直接行 IVF,每例单活胎所需医疗成本更高。敏
感度分析提示直接行 IVF,每例单活胎所需医疗成本降
低,并且更易获得活产 (55.1%),其每例单活胎所需医
疗成本(1l 432美元)低于制定的基本医疗成本。结论:
鉴于发生 HOMP的风险及高医疗成本,直接 IVF者每
例单活胎所需医疗成本高于应用促性腺激素后再行体
外受精者。
