“…This result is consistent with the findings of Iguer-Ouada and Verstegen (2001) and Tsutsui et al (2003) who reported that number of motile spermatozoa in chilled canine semen decreased gradually during storage at 4° C. This decrease in spermatozoa motility is due to initial increase of spermatozoa metabolism that increased uptake of oxygen and energy, and hence resulted in increased lactic acid concentration and decreased pH (Verstegen et al, 2005). Apart from that, osmotic pressure increases upon storage due to the accumulation of metabolic end products (Salisbury and Lodge, 1962). Songsasen et al (2002) reported that canine spermatozoa progressive motility was very sensitive to osmotic stress.…”

“…High temperatures (around 38C) increase sperm metabolism and shorten survival, whereas, at 4C, sperm are able to remain viable for a long period of time by halting their movements [14]. The epididymides of animals are normally anaerobic, have low pH and do not contain carbohydrates as a source of energy; therefore, respiration and glycolysis are suppressed in sperm, and they remain viable for approximately one month [11]. However, since blood flow stops and postmortem autolysis occurs after the death of a male animal or epididymis removal [2], sperm quality is considered to deteriorate markedly.…”

“…Spermatozoa motility has decreased as a result of an early increase in metabolism that consumes oxygen and energy and, in turn, caused an increase in lactic acid concentration and a drop in pH (Verstegen, Onclin, & Iguer-Ouada, 2005). In addition, Osmotic pressure rises during storage due to the accumulation of metabolic end products (Salisbury & Lodge, 1962). Also, progressive motility of canine spermatozoa was sensitive to osmotic stress (Songsasen et al, 2002).…”
