Resumo
The objective of this study was to describe and compare the head morphometry of normal and pathological sperm from Saimiri macrodon. In the morphological analysis, 39% of the sperm had normal morphology, and 61% had major or minor defects, with pathology in the tails being the most frequent with 47% (38% curled tail, 7% folded tail and 2% strongly folded tail). Among the evaluated head morphometry parameters, area (A), width (L) and ellipticity (E) showed statistical difference (p>0.05) between normal and pathological sperm. The average head area and width was lower in normal sperm (p=0,01 e p=0,04, respectively), and the mean ellipticity was higher (p=0,038), when compared to pathological sperm. This definition of the sperm morphometric parameters of S. macrodon is important for the samples selection destined to reproduction biotechnologies and for the clarification of taxonomic and evolutionary issues in the genus Saimiri.
