Chromatin and morphometry alterations of bovine sperm head after Percoll (TM) density gradient centrifugation
(Elsevier B.V., 2011-11-01)
The aim of this work was to assess the morphometry and chromatin integrity of bovine sperm head after a three layers discontinuous Percoll (TM) density gradient centrifugation. Frozen semen doses were obtained from six ...

Spermiogram and sperm head morphometry assessed by multivariate cluster analysis results during adolescence (12-18 years) and the effect of varicocele
(Asian Journal of Andrology, 2016)
This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche ...

Morphometric characterization and classification of alpaca sperm heads using the Sperm-Class Analyzer (R) computer-assisted system
(ELSEVIER SCIENCE INC, 2002-03-01)
Sperm morphology has been identified as one characteristic which can be useful in the prediction of sperm fertility, therefore, we hope that this study aimed at establishing standardized morphological criteria might serve ...
Identification of sperm head subpopulations with defined pleiomorphic characteristics in ejaculates of captive Goeldi's monkeys (Callimico goeldii)
(2013-02-01)
The aim of this study was to evaluate the incidence of pleiomorphisms and its influence on the distribution of sperm morphometric subpopulations in ejaculates from the vulnerable Goeldi's monkey (Callimico goeldii) by using ...
Spermatozoa characterization in the one-sided livebearing Jenynsia multidentata (Cyprinodontiformes: Anablepidae)
(Universidad de Costa Rica, 2014-09)
Several sperm parameters have been employed as useful tools to evaluate fish fertility. Within teleosts, approximately 3% of fish species are known to be viviparous. The Order Cyprinodontiformes includes several species ...
Sperm morphometry and chromatin condensation in Nelore bulls of different ages and their effects on IVF
(2017-01-01)
The aim of this study was to evaluate the chromatin packing and sperm head morphometry of cryopreserved semen of Nelore bulls (Bos taurus indicus) of different ages. Furthermore, the influence of the degree of chromatin ...
