A peculiar deformation of cock spermatozoa (neck-bending) caused by osmo- and thermoshock, and its significance for artificial insemination of fowl



A peculiar deformation of cock spermatozoa (neck-bending) caused by osmo- and thermoshock, and its significance for artificial insemination of fowl



VIIth International Congress on Animal Reproduction and Artificial Insemination, Munich, 1972, Summaries: 340



Neck bending of spermatozoa is a post-ejaculatory deformation peculiar to cock semen. It is primarily induced by hypotonicity of the diluent which produces swelling of the mitochondrial helix of the midpiece, disruption of its outer membrane and, finally, neck bending. This osmotic shock can also be activated by thermal shock due to sudden cooling.
