dc.description.abstract | The aim of this study was to evaluate if hormonal treatment causes changes in the morphology of matrinxã Brycon amazonicus spermatozoa. Twelve males were randomized into three treatment groups: 1, Ovaprim™ (0.5 ml/kg); 2, carp pituitary extract (CPE; 2.0 mg/kg); and 3, NaCl solution 0.9% - control group (0.5 ml/kg); with four replicates. Morphological sperm analysis was performed using an optical and scanning electron microscope. The percentage of normal spermatozoa (49.6±4.6% to 60.8±2.8%), with primary (26.1±6.4% to 45.3±4.5%) and secondary abnormalities (4.4±2.9% to 13.9±3.5%) did not differ significantly between treatment groups. There were no significant differences between treatments in relation to the primary abnormalities found in the head (10.5±3.8% to 25.5±6.3%), the midpiece (0.1±0.1% to 0.2±0.2%) and in the flagellum (18.9±3.8% to 15.5±3.1%), as well as in the secondary abnormalities, located in the head (0.8±0.4% to 7.8±4.6%) and in the flagellum (2.2±1.1% to 6.1±1.5%). When each abnormality was evaluated individually, only the percentage of degenerated head was higher in the CPE-induced group (24.9±5.9%) than the control group (7.2±3.1%). We concluded that the use of pituitary extract of carp or Ovaprim™ under the conditions of this experiment does not influence the percentage of sperm abnormalities in B. amazonicus. © Cambridge University Press 2018. | en |
