The Usefulness of Selected Physicochemical Indices, Cell Membrane Integrity and Sperm Chromatin Structure in Assessments of Boar Semen Sensitivity
Boar Chromatin Structure Sperm Membrane Integrity Sperm Morphology
2016/5/19
The present work describes experiments undertaken to evaluate the usefulness of selected physicochemical indices of semen, cell membrane integrity and sperm chromatin structure for the assessment of b...
Some Factors Affecting Freezing of Boar Semen in 5 ml Maxi-straws
Boar Semen Freeze 5 ml Maxi-straw
2016/4/29
A series of experiments were conducted to determine the suitable freezing and thawing temperatures for the freezing of boar semen in 5 ml maxi-straws. The ultrastructure, in vitro fertilization (IVF) ...
Choice of operating conditions to minimize sperm subpopulation sampling bias in the assessment of boar semen by computer-assisted semen analysis
CASA computer semen analysis tracking semen
2009/2/16
The performance of a computer-assisted semen analysis system was evaluated for use with washed boar spermatozoa. Accuracy was tested using a computer graphics-generated series of spots moving along ...
Morphologically distinct sperm subpopulations defined by Fourier shape descriptors in fresh ejaculates correlate with variation in boar semen quality following cryopreservation
sperm subpopulations Fourier shape descriptors fresh ejaculates boar semen quality
2008/12/26
This study investigated two hypotheses: 1) that consistent between-boar variation in frozen semen quality exists and is genetically determined, and 2) that morphologically distinct subpopulations...
Inhibition of Alkaline Phosphatase Activity of Boar Semen by Pentoxifylline, Caffeine, and Theophylline
Methyl xanthines seminal plasma spermatozoa
2008/12/15
Methyl xanthines have been used frequently as additives to sperm suspensions in order to improve sperm characteristics. The mechanism of action on spermatozoa is generally assumed to be inhibition of ...
