Abstract

In recent years, in addition to conventional methods, sperm selection by microfluidic system is being applied and gradually becoming more popular in IVF. This is an experimental study on 30 semen samples to compare the quality of sperm preparation by 2 methods: density gradient method (control group) and microfluidic sperm sorting chip (intervention group). The results showed that the sperm DNA fragmentation index (DFI) of the microfluidic group (0.67 ± 0.53%) was significantly lower than that of the density gradient group (1.18 ± 13.73%). The progressive motile sperm recovery rate was higher in the group using the microfluidic system (32.14 ± 18.14 vs 39.75 ± 19.20). Our data also showed that the vitality and mobility of sperm in the microfluidic group was higher than in the density gradient group (97.9 ± 2.21 vs 96.56 ± 4.11%, 96.36 ± 2.60 vs 95.06 ± 2.35%, respectively). However, there was no difference in the percentage of spermatozoa with progressive motility and sperm morphology between the two groups. Based on the aforementioned result, microfluidic system is a potential option for preparing sperm to improve the DNA fragmentation index.
