Reproductive tract modifications of the boar sperm surface [PDF]

Molecular Reproduction and Development, 2017
The sperm cell has a unique, polarized, and segregated surface that is modified extensively by the changing environments in both the male and the female reproductive tracts. The sperm cannot refresh its surface, as protein translation and membrane recycling by intracellular vesicular transport have ceased upon its maturation.

Lowering Sperm Dose Rates in Frozen Semen for Bovine Artificial Breeding [PDF]

, 2007
The New Zealand Dairy industry relies on artificial breeding to produce high genetic merit replacement stock. Proven bull semen is extended and preserved as either ambient temperature product or as frozen doses.

Molecular Profiling of Extracellular Vesicles Isolated from Boar Reproductive Fluids

Journal of Extracellular Vesicles, Volume 15, Issue 7, July 2026.
ABSTRACT Extracellular vesicles (EVs) are small membrane‐bound structures that facilitate intercellular communication in the reproductive system, modulating gamete maturation, capacitation, immunomodulation and fertilization. Despite pigs’ high relevance as a biomedical model, many aspects of EV biology remain poorly understood.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, Volume 14, Issue 5, Page 1249-1260, July 2026.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

Effects of Turine and Vitamin E on Sperm Viability, Membrane Integrity and Mitochondrial Activity damaged by Bromopropane in Fresh Boar Semen

Journal of Animal Reproduction and Biotechnology, 2016
The purpose of this study was to examine the effects of taurine and vitamin E on sperm characteristics damaged by bromopropane (BP) in pig. We evaluated toxicity of BP on viability, membrane integrity and mitochondrial activity of spermatozoa. 1-BP (0, 2.

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

Andrology, Volume 14, Issue 5, Page 1089-1101, July 2026.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Binding of pig sperm receptor in the zona pellucida to the boar sperm acrosome [PDF]

Reproduction, 1995
Abstract Pig zona pellucida (ZP) contains three families of glycoproteins: PZP2, PZP3α and PZP3β. PZP3α mediates the binding of the ZP to spermatozoa. In this study, the binding site of pig ZP on boar spermatozoa and the zona-binding proteins of boar spermatozoa were studied using chemically modified zona glycoproteins or anti-pig ZP ...
