Post-mating morphological changes in the spermatozoon and spermatophore wall of the crayfish Astacus leptodactylus: Insight into a non-motile spermatozoon
Popis výsledku v původním jazyce
Morphology of the crayfish spermatozoon and of the spermatophore wall during three stages of final maturation including freshly ejaculated, post-mating, and after spermatozoa release was studied and compared. The crayfish spermatophore consists of a sperm mass enveloped by a three layered spermatophore wall. After mating, the thickness of the outer layer of the spermatophore is increased. The matrix in the middle layer of the spermatophore becomes reticulated, and granules inside this layer release their contents. Fibers in the inner layer degrade to small particles. The spermatozoon capsule swells and the space between the capsule and the spermatozoon appears. The area of the plasma membrane is increased by wrinkling of the surface and alteration froma single to a multilayered structure at the anterior part of the acrosome. The density of the subacrosome zone increases in the vicinity of the main body of the acrosome. With the onset of fertilization, the layers of the spermatophore a
