Mitochondria Content and Activity Are Crucial Parameters for Bull Sperm Quality Evaluation
Standard sperm evaluation parameters do not enable predicting their ability to survive cryopreservation. Mitochondria are highly prone to suffer injuries during freezing, and any abnormalities in their morphology or function are reflected by a decline of

Post-Meiotic Intra-Testicular Sperm Senescence in a Wild Vertebrate [PDF]
There is growing interest in sperm senescence, both in its underlying mechanisms and evolutionary consequences, because it can impact the evolution of numerous life history traits. Previous studies have documented various types of sperm senescence, but
