To investigate this, a lot of simulation study including ACV's voyage and turning performance has been done. It was found that the voyage simulation results were accorded with ACV own characteristic and turning simulation results were accorded with USA ACV's movement characteristic basically.展开更多

Oocyte retrieved, fertilization rate, cleavage rate, available embryo rate, pregnancy rate and miscarriage rate were analyzed to explore whether serum TSH level was correlated with the results of lVF/ICSI.Results There were no differences in number of oocyte retrieved, fertilization rate, cleavage rate and available embryo rate among 3 groups （P〉0.05）. Clinical pregnancy rate in group B （43.0%） was significantly higher than that in group A （30.2%） and group B （23.5%）, respectively （P〈0.05）. There were no significant differences in miscarriage rate among 3 groups.Conclusion TSH level has no effect on fertility rate or miscarriage rate in patients undergoing IVF/ICSL Inadequacy TSH level would decrease the IVF/ICSI pregnancy rate.展开更多
