from Section 4 - Laboratory Evaluation and Treatment of Male Infertility

The prevalence of azoospermia in the general population is 1% and azoospermic men constitute approximately 10–15% of all infertile men. While the advent of microTESE substantially improved sperm recovery compared to standard biopsy or other techniques, the procedure remains inefficient, costly, and very time consuming, both in retrieval and separation/sorting. Three conventional sperm sorting techniques are commonly used in andrology clinics: density gradient centrifugation, sperm washing, and swim-up, all of which have provided reliable solutions to isolate normal sperm from highly concentrated semen samples. The field of microfluidics is the most rapidly developing field for sperm selection related to the field of ART. It is particularly powerful when considering applications in single-cell or low-cell number analyses. Magnetically activated cell sorting and fluorescence-activated cell sorting are alternative and promising technologies. Further research is needed to optimally identify and isolate sperm to help couples achieve the goal of biologic children.
