Description
| - Sperm morphology, acrosome reaction and motility are reviewed in sturgeon (Chondrostei, Acipenseriformes). The elongated head of spermatozoon comprises an acrosome with 8-12 posterolateral projections. Three endonuclear canals are observed in the head. Proximal and distal centrioles and 3-6 mitochondria are located in the midpiece. The flagellum consists of an axoneme with %229+2%22 structure of microtubules and presents a ribon-like structure fins. Egg water, Ca2+ and Mg2+ can trigger acrosome reaction. Protease activity is reported in sturgeon sperm that were identified as serine activity with 33kDa molecular mass and can be inhibited by their respective inhibitors. The K+ prevents sperm activation in seminal plasma, thus hypo-osmolality or decrease of extracellular K+ triggers sperm activation. Extracellular Ca2+ is involved in flagellar beating pattern and sperm velocity. After activation, sperm motility, velocity, and flagellar beating frequency, wavelength and amplitude decrease, while number of waves and curvature increase.
