简要总结
Microfluidic chips are one of the methods of sperm separation to eliminate DNA fragmentation in sperm. It is thought that the separation of sperm by centrifugation in the classical gradient density (Percoll) method used in sperm separation in IVF (in vitro fertilization) laboratories leads to the increase of reactive oxygen radicals in sperm and this leads to sperm DNA fragmentation. Studies comparing Percoll and microfluidic chip method in terms of sperm, embryo quality and pregnancy rates are limited. In this context, it is aimed to investigate the effect of Percoll or Microfluidic Chip Technology on the quality of sperms and embryos obtained with these sperms and their pregnancy rates prospectively.
详细描述
The increase in male infertility rate due to environmental and physiological conditions leads to an increase in the use of assisted reproductive techniques. Isolation of living and morphologically normal live sperm is an integrated procedure in commonly used IVF / ICSI(intracytoplasmic sperm injection) / IUI(intrauterine insemination) procedures. Although current IVF / ICSI procedures result in a successful pregnancy of around 50%, the process can be greatly compromised if the selected sperm is abnormal. Microfluidic chips are one of the recommended sperm separation methods to eliminate DNA fragmentation in sperm. It is thought that the separation of the sperm by centrifugation in the classical gradient density (Percoll) method which is used in the separation of sperm in the IVF Laboratories, causes the increase of reactive oxygen radicals in sperm and this leads to sperm DNA fragmentation. Studies comparing Percoll and microfluidic chip method in terms of sperm, embryo quality and pregnancy rates are limited. In this context, it is aimed to investigate the effect of Percoll or Microfluidic Chip Technology on the quality of sperms and embryos obtained with these sperms and their pregnancy rates prospectively.

结局指标
主要结局
Compare microfluid chip and density-gradient methods in terms of embryo quality
时间窗: average of 1 year
Embryo morphology will be assessed on day 3 using the standard criteria of the number of blastomeres and extent of fragmentation and blastomere asymmetry. Top quality embryos on day 3 will be designated as embryos with 7-8 cells, ≤10% fragmentation, and symmetric blastomeres. Using these criteria, the rate of top quality embryos will be analyzed.
