The average relative quantities of mtDNA observed in association with female age at the cleavage stage.

The mtDNA values (2-Delta Delta Ct) were obtained during real-time PCR analysis. All examined blastomeres were characterised as being chromosomally normal.
The average relative quantities of mtDNA observed in association with female age at the cleavage stage.

本研究通过实时聚合酶链反应（real-time PCR）分析，获取了线粒体DNA（mtDNA）的2^(-ΔΔCt)值；所有受检卵裂球均被鉴定为染色体正常。
本研究观测到的线粒体DNA平均相对含量，与卵裂期女性年龄存在关联。
