Relationship between sperm ATP content and motility of carp spermatozoa.
Carp spermatozoa are immotile in seminal plasma or in saline solution of high osmolality (> 400 mosmol kg-1). These 'quiescent' spermatozoa initiate a progressive forward motility when transferred in freshwater or in saline solution with low osmolality (< 160 mosmol kg-1). In this study we investigated 'in vitro' the relationship between sperm ATP content (measured by bioluminescence) and sperm...
متن کاملDetermination of some seminal plasma indices, sperm density and sperm motility in the Persian sturgeon Acipenser persicus
Some biological aspects of semen were investigated in the Persian sturgeon, Acipenser persicus, by determination of seminal plasma indices (ionic composition and osmolality), sperm density and their relationships with sperm motility. The osmolality of seminal plasma ranged from 42.00 to 111.00 mOsmol Kg-1. The concentrations of Sodium (Na+), Potassium (K+), Chloride (Cl-), Calcium (Ca2+) and Ma...

متن کاملEvidence favoring sperm selection over sperm competition in the interaction between human seminal plasma and sperm motility in vitro.
The effect on sperm motility of sperm-sperm and sperm-seminal plasma interactions was studied among homologous and heterologous sperm. There were no significant interactions between sperm in vitro, but it was found that seminal plasmas of different donors have different effects on sperm motility, and different sperm react differently to the same seminal plasma. Sperm showed higher motility in a...
متن کاملChanges in motility, ATP content, morphology and fertilisation capacity during the movement phase of tetraploid Pacific oyster (Crassostrea gigas) sperm.
Changes in sperm features during the movement phase are especially interesting to study in external fertilization species whose sperm duration movement is long because this implies a significant adaptation of moving cells to the external medium. This study describes the changes in tetraploid Pacific oyster sperm characteristics in relation to time post activation. Sperm individually collected o...
