Sperm sexing with density gradient centrifugation in dogs
(Elsevier B.V., 2018-12-01)
Sexed sperm in dogs is of interest because of being polytocous, and as a result, the greatest number of offspring of the same sex can improve the market, although few studies assessing sperm sexing have been performed in ...
Sperm sexing mediated by magnetic nanoparticles in donkeys, a preliminary in vitro study
(Elsevier Science Inc, 2018-06)
Preselection of sex before conception has been one of the objectives pursued by scientists and breeders for many years. The donkey milk industry has shown a greater commercial interest, since jennies’ demand is increasing ...
Effect of different mini-volume colloid centrifugation configurations on flow cytometrically sorted sperm recovery efficiency and quality using a computer-assisted semen analyzer
(Wiley Blackwell Publishing, Inc, 2018-02)
Straws of sex-sorted sperm are usually packaged at a low concentration (e.g., ~2.1 × 106 sperm/ml) and cost significantly more than unsorted conventional semen from the same sire. In order to maximize the efficiency of ...
Physical and morphological characteristics of the first three jets of pêga jackasses sperm-rich fraction
(2016-01-01)
The first three jets of the sperm-rich fraction of Pêga jackasses were collected and assessed separately. Five fertile Pêga jackasses were used as semen donors and underwent fractionated semen collection, using an open ...
Effects of semen storage and separation techniques on sperm DNA fragmentation
(ELSEVIER SCIENCE INC, 2010)
Objective: To determine the effect of semen storage and separation techniques on sperm DNA fragmentation. Design: Controlled clinical study. Setting: An assisted reproductive technology laboratory. Patient(s): Thirty ...
Sperm phospholipid methyltransferase activity during preparation for exocytosis
(1994)
The present report describes experiments to evaluate phospholipid methyltransferase activity in golden hamster spermatozoa incubated under different conditions. Washed cauda epididymal sperm were incubated with taurine, ...
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 ...
Differential distribution of sperm subpopulations and incidence of pleiomorphisms in ejaculates of captive howling monkeys (Alouatta caraya)
(Springer, 2013-10-01)
The aim of this study was to develop an objective method to determine the incidence of pleiomorphisms and its influence on the distribution of sperm morphometric subpopulations in ejaculates of howling monkeys (Alouatta ...
Effects of Pentoxifylline on Equine Epididymal Sperm
(2013-06-24)
This study evaluated whether pentoxifylline (PTX) present in the flushing extender influenced the function of equine epididymal spermatozoa after recovery and after thawing. For this experiment, 58 testicles from 29 Brazilian ...
