Validation of the polysemen admixture on viability and acrosomal morphology of boar spermatozoa [PDF]
Online Journal of Health & Allied Sciences, 2007 Semen were collected using artificial vagina (AV), from 5 large white boars aged 2-2.5 years twice a week for 16 weeks in each of the two seasons, early rainy (ER) and late rainy (LR) seasons, to determine the effects of multiple semen pool admixture on ...

Effects of Fluorescence-Activated Cell Sorting on Boar Sperm Motility Subpopulations and In Vitro Embryo Development. [PDF]
Mol Reprod DevEffects of fluorescence‐activated sperm sorting on IVF outcomes and motility subpopulations. Distinct boar ejaculates were either used directly for in vitro fertilization (IVF; control, unsorted) or processed by fluorescence‐activated cell sorting to generate a sorted sperm population.

Cysteine improves boar sperm quality via glutathione biosynthesis during the liquid storage [PDF]
Animal Bioscience, 2022 Objective Sperm is particularly susceptible to reactive oxygen species (ROS) stress. Glutathione (GSH) is an endogenous antioxidant that regulates sperm redox homeostasis.

Camellia oil with its rich in fatty acids enhances post-thawed boar sperm quality. [PDF]
Acta Vet ScandBackground Boar sperm are highly susceptible to specific conditions during cryopreservation, leading to a significant decrease in their fertilizing potential due to damage to their membranes.

Pig Spermatozoa Defect in Acrosome Formation Caused Poor Motion Parameters and Fertilization Failure through Artificial Insemination and Fertilization [PDF]
Asian-Australasian Journal of Animal Sciences, 2014 The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of semen mainly include total sperm motility, concentration,

Scrotal insulation and sperm production in the boar [PDF]
Molecular Reproduction and Development, 2017 Seasonal infertility is a limiting factor in boar fertility, and is increasingly important as climate changes. Spermatogenesis in the boar produces 256 spermatozoa per type A1 spermatogonium, but the process is inefficient such that only 10–30% of these potential spermatozoa are actually produced.
