Limulus spermatozoa are nonmotile after dilution into sea water, and motility is initiated in situ by a sperm motility-initiating peptide (SMI) that emanates from Limulus eggs. In the absence of SMI, several structurally different chelators (EDTA, EGTA, phenanthroline, dipyridyl, cysteine, and dithi
## Abstract In salmonid fish, spermatozoa taken from the testes are immotile, but acquire motility during their passage through the sperm duct. Using male masu salmon (__Oncorhynchus masou__), we found that gonadotropinβinduced testicular production of 17Ξ±,20Ξ²βdihydroxyβ4βpregnenβ3βone (17Ξ±,20Ξ²βDP)
