Intracellular changes in Ca2 +, K+ and pH after sperm motility activation in the European eel (Anguilla anguilla): Preliminary results
P. 155-158 Although it is widely accepted that osmolality and ion fluxes are the main factors triggering sperm motility in fish, a complex universal mechanism for sperm motility activation does not exist in fish, and studies of marine fish species are even more scarce. Therefore, the main goal of th...
