Abstract
Cooperative behaviour of sperm is one of the mechanisms that plays a role in
sperm competition. It has been observed in several species that spermatozoa
interact with each other to form agglomerates or bundles. In this study, we
investigate the effect of physical and biochemical factors that will most likely
promote bundle formation in bull sperm. These factors include fluid viscosity,
swim-up process, post-thaw incubation time and media additives which
promote capacitation. While viscosity does not seem to influence the degree
of sperm bundling, swim-up, post-thaw migration time and suppressed
capacitation increase the occurrence of sperm bundles. This leads to the
conclusion that sperm bundling is a result of hydrodynamic and adhesive
interactions between the cells which occurs frequently during prolonged
incubation times.
