A previous study reported that sperm mitochondrial activity and sperm motility can be evaluated by combined flow and image cytometry, suggesting their potential interest in fertility clinical applications and for studying the effect of physical and chemical agents that modify sperm motility and/or metabolism. This paper focuses on the effect of freezing sperm in liquid nitrogen, extensively used in artificial insemination (AI), combined with different sperm manipulations (washing, swim-up in capacitating medium, CM) using flow and image cytometry on sperm samples from three fertile donors. Rhodamine 123 (Rh123) uptake profiles were bimodal both for fresh and frozen/thawed samples. The mean value of fluorescence of active cells (m+) remained nearly similar after freezing while the percentage of active cells (%C+) was significantly decreased and the percentage of dead cells (%dc, revealed by propidium iodide uptake) significantly increased. In all experiments, the decrease of MOT (percentage of motile sperm) due to freezing was concomitant, to a smaller extent, with a drop in %C+ and an increase in %dc; there was a good relationship between velocity (VCL, VSL) or trajectory characteristics (ALH) and the mean fluorescence values of active cells (m+). Sperm immobilization was neither found related to a major decrease of Rh123 fluorescence nor to an increase in dead cells.
