Usage of polyvinylalcohol and polyvinylpyrrolidone for preparation of thawed ejaculated boar sperm for fertilization by ICSI

open access: yesБіологія тварин, 2022
The aim of the study was to explore the effect of PVP (polyvinylpyrrolidone) and PVA (polyvinyl alcohol) media on deconserved ejaculated boar sperm and their preparation for artificial insemination to optimize biotechnological approaches.

Novel Flow Cytometry Analyses of Boar Sperm Viability: Can the Addition of Whole Sperm-Rich Fraction Seminal Plasma to Frozen-Thawed Boar Sperm Affect It? [PDF]

open access: yesPLoS ONE, 2016
Boar semen cryopreservation remains a challenge due to the extension of cold shock damage. Thus, many alternatives have emerged to improve the quality of frozen-thawed boar sperm.

Bisphenol A Diglycidyl Ether (BADGE) and Progesterone Do Not Induce Ca2+ Signals in Boar Sperm Cells

open access: yesFrontiers in Physiology, 2020
AimExposure of boar sperm cells to Bisphenol A diglycidyl ether (BADGE) has been shown to lead to reproductive failure in sows, however, the mode of action is unknown. As we have recently shown that BADGE can interfere with Ca2 + signaling in human sperm

Post-Thaw Storage Temperature Influenced Boar Sperm Quality and Lifespan through Apoptosis and Lipid Peroxidation

open access: yesAnimals, 2023
Cryopreservation deteriorates boar sperm quality and lifespan, which restricts the use of artificial insemination with frozen-thawed boar semen in field conditions.

Sperm function and mitochondrial activity: An insight on boar sperm metabolism [PDF]

open access: yesTheriogenology, 2020
In this study boar sperm mitochondrial activity was studied and deepened in order to delineate the main metabolic strategies used by boar sperm to obtain energy and to link them to sperm function. Boar spermatozoa were collected, diluted at 30 × 106 spz/mL and incubated for 1 h with: Rotenone (ROT), complex I inhibitor, Dimethyl-malonate (DMM), complex

Boar semen proteomics and sperm preservation

open access: yesTheriogenology, 2019
Recently numerous proteomic approaches have been undertaken to identify sperm and seminal plasma (SP) proteins that can be used as potential biomarkers for sperm function, including fertilization ability. This review aims firstly to briefly introduce the proteomic technologies and workflows that can be successfully applied for sperm and SP proteomic ...

Implication of Polyhistidine, a Novel Apoptosis Inhibitor, in Inhibiting Lipopolysaccharide-Induced Apoptosis in Boar Sperm

open access: yesAnimals, 2019
Lipopolysaccharide (LPS) released from Gram-negative bacteria binds to toll-like receptor 4 (TLR4) and induces boar sperm apoptosis. Similarly, polyhistidine (pHis), a TLR4 agonist, can also bind to TLR4.

Effect of Tunicamycin on Viability, Motility, Reactive Oxygen Species, Nitric Oxide, and Lipid Peroxidation in Boar Sperm [PDF]

open access: yesAnimals
Tunicamycin induces endoplasmic reticulum stress in mammalian cells. Our study aimed to investigate the effect of tunicamycin on the motility and viability of sperm, reactive oxygen species, nitric oxide, and lipid peroxidation in boar sperm.

Influence of progesterone on boar sperm capacitation

open access: yesJournal of Endocrinology, 1995
Abstract This research investigates the effect of progesterone (P4) on boar sperm capacitation. Ejaculated spermatozoa were washed and incubated under capacitating conditions with or without P4. At different times of incubation samples of sperm were exposed to solubilized zonae pellucidae (ZP) and the degree of capacitation was evaluated by the

Sperm quality improvement of cryopreserved boar semen through colloidal centrifugation gradient

open access: yesCzech Journal of Animal Science
Boar semen cryopreservation is limited due to the lower thermal shock resistance of sperm cells. A colloidal centrifugation gradient is an enhancement to cryopreservation that could improve the frozen boar semen quality.
