dc.descriptionThe study aimed to evaluate the effect of short-term heat stress on sperm morphology, relating them to the stages of spermatogenesis. Adult buffalo bulls underwent scrotal insulation (day 0; 48 hours). Semen samples were collected every 7 days (day -7 to day 49) and analyzed. Heat stress destabilized scrotal thermoregulation (36.1±0.3 °C and 35.5±2.3 °C, after 24 and 48 hours of insulation) and returned to baseline five days after removal of the stressor stimulus (33.2±0.6°C). The sequential expression of the morphological defects showed tail defects (days 7 to 14), cytoplasmic droplets (days 14 to 28) and sperm head defects (day 28). Hyperthermia more severely damaged sperm in epididymal transit, elongated sperm and secondary spermatocytes. Thus, buffalo bulls presented a peculiar manifestation of sperm morphological defects after short-term stress, indicating an important difference regarding the bovine species. Therefore, during the andrological evaluation, allometric extrapolation between these species should be avoided.
