Abstract: Objective To explore the mechanism of Wenshen Yangxue Decoction in improving oocyte quality and embryo development potential in older female rats.Methods Eight-month-old ICR mice were divided into control group, pregnant mare serum gonadotropin (PMSG) group, Wenshen decoction, Yangxue decoction and Wenshen Yangxue decoction according to random number table method. The fertilization rate and cleavage rate of every group after treatment were recorded, and the expression of mitochondria in oocyte and fertilized eggs were examined. Results The fertilization rate and cleavage rate of Wenshen Yangxue decoction, Wenshen decoction and Yangxue decoction were significantly higher than those of the control group and PMSG group (P<0.05). The fertilization rate and cleavage rate of Wenshe Yangxue decoction were the highest (P<0.05). The 2 cell rate, 4 cell rate, 8 cell rate, morula rate and blastocyst rate of Wenshen Yangxue decoction were higher than in the PMSG group (P<0.05). The mitochondrial DNA copy number in oocytes and fertilized eggs of Wenshen Yangxue decoction was the highest of the five groups, which was statistically significant compared with the control group(P<0.05). Conclusion Wenshen Yangxue decoction may improve oocyte quality and embryo development potential by regulating oocyte mitochondrial DNA copy number.
