Diagram showing the consequences of the contamination of bacterial communities in boar sperm and how they directly influence sperm quality parameters during cold storage. The presence of bacteria in boar semen has significant consequences on the quality and functionality parameters of spermatozoa: damage to the acrosome, decreased mitochondrial membrane potential, cryoresistance, sperm motility, and integrity of the sperm membrane, and increased ROS and apoptosis.
