Alkaline phosphatase in boar sperm function [PDF]
Andrology, 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 estrogens on boar sperm capacitation in vitro [PDF]
Reproductive 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 ...

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

Optimization of the Thawing Protocol for Iberian Boar Sperm
Animals, 2022 Thawing protocols have been barely studied, and their modifications may lead to a substantial improvement in post-thawing sperm quality, which could be of great relevance to existing sperm banks, such as those for Iberian pig breeds with varieties in danger of extinction.

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

Boar semen proteomics and sperm preservation
Theriogenology, 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 ...
