摘要

目的了解短时受精对体外受精-胚胎移植（in vitro fertilization and embryo transfer

IVF-ET）结局的影响。方法选择在本生殖医学中心接受常规IVF治疗的248个周期，通过一定条件限制将其分为短时受精组和过夜受精组，将248个常规IVF周期中的卵子进行配对资料（同一IVF周期同时进行短时受精和过夜受精者

共20个周期）和非配对资料（1个IVF周期只采用1种方式受精者，过夜受精组177个周期，短时受精组51个周期）研究，比较短时受精组和过夜受精组的正常受精（2PN）率、多精受精率、卵裂率、优质胚胎率及临床妊娠率。结果无论配对还是非配对资料，短时受精组的正常受精（2PN）率、多精受精率、卵裂率、优质胚胎率、临床妊娠率等与过夜受精组比较均无统计学差异(P0.05）；在非配对资料中，短时受精组的移植优胚率（77.33±36.69）%明显高于过夜受精组（64.04±41.85）%（P0.05），而在配对资料中，用于移植的优质胚胎率短时受精组和过夜受精组无统计学差异（P0.05）。结论短时受精是一种安全、有效的受精方式，但不能改善胚胎质量和妊娠结局。

Abstract

Objective To investigate the effects of short gamete (sperm - oocyte) co - incubation on outcomes of

in vitro

fertilization and embryo transfer (IVF - ET). Methods All oocytes from 248 IVF - ET cycles in our department from October 2008 to September 2009 were studied in pair and non - pair design. They were divided with some condition into shortened insemination group and overnight insemination group. Their IVF outcomes were analyzed. Results All pair and non - pair data showed that there was no significant difference in the number of retrieved oocytes

percentage of oocytes at M Ⅱ stage

dip

loid fertilization rates (two pronuclei

2PN)

polyspermy (2PN) rates

cleavage rates

high quality embryo rates and the pregnancy rates between shortened insemination group and overnight fertilization group(

0 . 05). The high quality embryo rates used for ET in shortened insemination group were significantly higher than those in overnight insemination group in the non - pair data(

0 . 05)

but no significant difference between shortened insemination and overnight fertilization groups was found in the pair data(

0 . 05). Conclusion Short gamete co - incubation is reliable and efficacious. However

it could not improve embryo quality.
