Abstract
Microfluidics and microfilter devices have been developed to mimic the characteristics of the female reproductive tract, minimizing the risk of sperm damage. This study aimed to compare the use of a microfilter device versus conventional methods for sperm selection used in in vitro fertilization (IVF). For selecting spermatozoa, the pooled samples were processed in a microfilter device, swim-up and mini-Percoll gradient. Kinematic and morphometric parameters, vitality and DNA damage were analysed before and after sperm selection. After selection, 10,000 motile spermatozoa per oocyte were used in IVF drops. Embryos were assessed at three (cleavage rate) and seven (blastocyst rate) days post-IVF. Results of sperm kinematic parameters including average path velocity, velocity straight line, curvilinear velocity, linearity, lateral head displacement with the microfilter device were superior to density gradient (p < 0.05), but similar to swim-up method. Likewise, sperm DNA damage was significantly reduced using the microfilter device and swim-up method. Regarding the total sperm recovery rate post selection, results with the microfilter device (17.64%) and mini-Percoll gradient (18.27%) were higher than with swim-up method (6.52%). However, the cleavage and blastocyst rates were the lowest using the microfilter device. In conclusion, sperm selection using the microfilter device and swim-up method can improve kinematic parameters, although the mini Percoll gradient was the most efficient method for embryo production.
