简要总结
Retrospective cohort study for 189 couples assigned to normal and abnormal Sperm DNA fragmentation (SDF) groups.To determine the effect of SDF on blastocyst's trophectoderm (TE), Inner cell mass (ICM) morphology grading, and implantation rate. Semen in both groups was processed by density gradient (DG).
详细描述
Purpose: to determine if sperm DNA fragmentation (SDF) has a correlation with Blastocyst's trophectoderm (TE) and Inner cell mass (ICM) grading, or with the implantation rate? Method: Retrospective cohort study for 189 couples, assigned to normal SDF group (121 cases), and abnormal SDF group (68 cases). Semen in both groups was processed by double layer density gradient (DG). Statistical analysis done using SPSS version 22.

结局指标
主要结局
Blastocyst morphological grading
时间窗: 5-6 days after ICSI
Morphological grading of trophectoderm and Inner cell mass using Gardner's criteria 1999, from grade A to C ( A is the highest quality).
Implantation rate
时间窗: 6 weeks of pregnancy
Percentage of the implanted embryos number for each group / number of transferred embryos.
次要结局
- Blastulation rate(5-6 days of ICSI)
- Pregnancy rate(After 2 weeks of embryo transfer)
- Fertilization rate(16-19 hours of ICSI)
