| ABSTRACT The present work reports a clinical case of a mongrel dog, with serological diagnosis of brucellosis, from which epididymal sperm analysis was performed. Sperm samples were collected from different segments of the epididymis (tail, corpus, and caput). Sperm samples were evaluated for computer-assisted motility analysis (CASA), spermatic morphology, mitochondrial activity and sperm plasmatic membrane and acrosomal integrity. Changes in sperm movement patterns were found (progressive motility, percentage of rapid sperm, percentage of rapid velocity, average pathway, curvilinear velocity, velocity straight line, amplitude of lateral head displacement, straightness and linearity), increase of total morphological defects (51%) and absence of sperm... |

| Hypobaric hypoxia is of interest due to an increase of human populations working at high altitude. Testicular damage is related to the physiological response (neoangiogenesis) to increased intrascrotal blood flow as temperature rises. Hypoxia is a stress factor with overproduction of reactive oxygen species (ROS). The effect of hypoxia in mice reproductive parameters is analyzed. Animals were exposed to simulated hypoxia of 4,200 meters above sea level (m.a.s.l.) in a chamber for 33.2 days, both to continuous (HH) or intermittent hypoxia (HI) with an intermittency period of 4 days hypoxia /4 days normoxia (500 m.a.s.l.). The anti-inflammatory drug Ibuprofen was administered to a group of mice to control vasodilation and increased blood flow. Melatonin was... |
