Design outcomes

Primary

MeasureTime frame
Oocyte cytoplasmic maturation. Timepoint: After 24-28 hours, the culture was incubated at 37 ° C and 5% CO2. Method of measurement: Cell Tracker Blue staining for oocyte cytoplasmic maturity.;Oocyte oxidative stress. Timepoint: After 24-28 hours, the culture was incubated at 37 ° C and 5% CO2. Method of measurement: Evaluation of the free radical oxygen (ROS) in cytoplasmic by staining with H2DCFDA.;Meiotic spindle structure. Timepoint: After 24-28 hours, the culture was incubated at 37 ° C and 5% CO2. Method of measurement: Evaluation of miieotic spindle structure by staining with anti-tubulin antibody.;Apoptosis rate. Timepoint: After 24-28 hours, the culture was incubated at 37 ° C and 5% CO2. Method of measurement: Determination of apoptosis rate by evaluating expression bax, bcl2 and caspase-3 gene by Real Time-PCR.;Nucleation maturation. Timepoint: After 24-28 hours, the culture was incubated at 37 ° C and 5% CO2. Method of measurement: Determining the oocyte nucleus maturity by evaluating expression of MPF and MAPK by Real Time-PCR.

Secondary

MeasureTime frame
Fertilization rate. Timepoint: 16-18 hours after ICSI. Method of measurement: Divide the total number of oocytes fertilized to the total oocytes under ICSI.;Cleavage rate. Timepoint: The third day after ICSI. Method of measurement: Split the total number of cleavage embryos divided into fertilized embryos.;Embryo quility. Timepoint: The third day after ICSI. Method of measurement: Grading of embryo morphology based on the number and size of the blastomeres and the rate of fragmentation.
