摘要
目的:观察显微激光薄化人胚胎透明带进行辅助孵出的效果。方法:应用1.48μm二极管激光打孔仪对50个胚胎进行透明带薄化辅助孵出,另外51个胚胎作为对照,体外囊胚培养,观察囊胚形成及孵出情况。结果:薄化组囊胚形成率(50.0%)与对照组囊胚形成率(45.1%)间差异无统计学意义(P>0.05);但薄化组囊胚发动孵出率和囊胚完全孵出率(88.0%,59.1%)均高于对照组(34.8%,12.5%)(P均<0.05)。结论:显微激光薄化人胚胎透明带辅助孵出能提高囊胚孵出率,是优于传统辅助孵出技术的一个好方法。
Aim： To study the hatching efficacy of human embryos subjected to laser zona pellucida thinning. Methods：Zona pellucida thinning was performed on 50 embryos using a 1.48 μm diode laser, the rate of resulting blastocysts and the hatching and hatched blastocysts was compared with 51 control embryos. Results： There was no statistic significance in the rate of resulting blastocysts between the treated group （50.0%） and control group（45.1% ） （P 〉 0.05 ）. The rates of hatching and hatched blastocysts were higher in the treated group （ 88.0% and 59. 1% ） than those in the control group （34.8% and 12.5% ） （P 〈 0.05 ）. Conclusion： Laser thinning assisted hatching increases the rates of hatching and hatched blastocysts, thus has advantages over conventional assisted hatching techniques.
