Alkaline phosphatase in boar sperm function [PDF]

open access: yesAndrology, 2013
SummaryAlkaline phosphatase (AP) catalyses the detachment of phosphate residues from different substrates. Its activity has been demonstrated in seminal plasma and spermatozoa from porcine and other mammalian species; anyway, the role of AP in male reproduction has not been clarified yet and the aim of this study was to determine AP function in boar ...

Effect of L-carnitine on sperm quality during liquid storage of boar semen [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2020
Objective This study was conducted to investigate the effect of L-carnitine on the pig semen characteristics during storage. Methods Spermatozoa samples were examined for spermatozoa quality and then randomly divided into 5 groups: 0 (control), 12.5, 25,

Reducing the Glucose Level in Pre-treatment Solution Improves Post-thaw Boar Sperm Quality

open access: yesFrontiers in Veterinary Science, 2022
Frozen–thawed boar sperm was not widely used in pig artificial insemination as the sperm quality was damaged by biochemical and physical modifications during the cryopreservation process.

Effect of estrogens on boar sperm capacitation in vitro [PDF]

open access: yesReproductive Biology and Endocrinology, 2010
Abstract Background Mammalian sperm must undergo a series of controlled molecular processes in the female reproductive tract called capacitation before they are capable of penetrating and fertilizing the egg. Capacitation, as a complex biological process, is influenced by many molecular factors, among which steroidal ...

Effects of Melatonin and Silymarin on Reactive Oxygen Species, Nitric Oxide Production, and Sperm Viability and Motility during Sperm Freezing in Pigs

open access: yesAnimals, 2023
Sperm during the freezing and thawing process is damaged by oxidative stress. Thus, its antioxidant scavenger is essential for sperm survival and death in frozen–thawed semen.

Sperm Response to in vitro Stress Conditions in Wild and Domestic Species Measured by Functional Variables and ROS Production

open access: yesFrontiers in Veterinary Science, 2021
The domestication process has resulted in profound changes in the reproductive physiology of the animals that might have affected the sperm characteristics and thus their sensitivity to handling and cryopreservation procedures.

Cryopreservation Induces Acetylation of Metabolism-Related Proteins in Boar Sperm. [PDF]

open access: yesInt J Mol Sci, 2023
Cryodamage affects the normal physiological functions and survivability of boar sperm during cryopreservation. Lysine acetylation is thought to be an important regulatory mechanism in sperm functions.

Automatic classification of the acrosome status of boar spermatozoa using digital image processing and LVQ [PDF]

open access: yes, 2006
We consider images of boar spermatozoa obtained with an optical phase-contrast microscope. Our goal is to automatically classify single sperm cells as acrosome-intact (class 1) or acrosome-damaged (class 2).

Effect of Seminal Plasma on the Freezability of Boar Sperm. [PDF]

open access: yesAnimals (Basel)
Background: Seminal plasma is an important component of semen and has a significant effect on sperm function. However, the relationship between seminal plasma and sperm freezing capacity has not been fully studied. Purpose: Exploring metabolites and proteins related to the boar sperm freezing capacity in seminal plasma, by metabolomic and proteomic ...

Investigation Into the Relationship Between Sperm Cysteine-Rich Secretory Protein 2 (CRISP2) and Sperm Fertilizing Ability and Fertility of Boars

open access: yesFrontiers in Veterinary Science, 2021
The proteins in the seminal plasma and on the sperm surface play important roles in sperm function and numerous reproductive processes. The cysteine-rich secretory proteins (CRISPs) are enriched biasedly in the male reproductive tract of mammals, and ...
