title: [Application of microfluidics in sperm isolation and in vitro fertilization].
abstract: Due to the low effectiveness of traditional assisted reproductive technology (ART), new technological possibilities are constantly explored. Lots of studies have demonstrated the potential of microfluidics to revolutionize the fundamental processes of in vitro fertilization (IVF). With the advantages of high efficiency, short time, harmless collection, real-time observation of separation, similar microenvironment, and automation, the application of microfluidics in sperm isolation and IVF has shown an evident superiority over the conventional approaches and provided a new platform for ART. This review highlights the application of various microfluidic techniques in sperm motility assessment and isolation, sperm chemotaxis assay, IVF, sperm concentration, and sperm separation and enrichment in recent years. It also briefly introduces the basic principles, structural design, and operation processes of the microfluidic platform, focusing on the advantages and disadvantages of each method and the potential of their clinical application. Obviously, there are still some challenges to the application of microfluidics in ART. However, it is believed that the development of this new technology would be toward a highly integrated application of several steps in one single device, known as IVF-lab-on-a-chip.
