- Serotonin-Induced Sperm Hyper-Motility In Pacific Oyster (Crassostrea Gigas) Associates With K Efflux and Membrane Hyperpolarization. Alavi, Sayyed Mohammad Hadi Barzegar-Fallah, Sepideh Yoshida, Manabu Butts, Ian A E Osada, Makoto Animals Male Serotonin Crassostrea Membrane Potentials Sperm Motility Potassium Spermatozoa Serotonin (5-HT) induces sperm hyper-motility in bivalves. This process has been suggested to be associated with K efflux due to higher concentrations of K ions in testicular fluid compared to that of seawater. This hypothesis was supported by inhibition of 5-HT-induced sperm hyper-motility in artificial seawater (ASW) containing high extracellular K ions or in the presence of a voltage-dependent K channel blocker (4-AP). Here, we studied changes of sperm membrane potential to elucidate 5-HT-induced sperm hyper-motility signaling in Pacific oyster (Crassostrea gigas). Sperm motility was partially initiated (48.34 ± 7.80%) in ASW, and decreased at 5 min post-activation (p
