BMC Veterinary Research, 2021 Background Cryopreservation is an efficient way to store spermatozoa and is closely associated with the quality of sperm after the freeze-thaw process. During freeze-thaw cycling, excessive reactive oxygen species (ROS) are produced, and the effects of ...

Studies on the sperm reservoir of the pig oviduct [PDF]
, 2003 During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

Non-random chromosome positioning in mammalian sperm nuclei, with migration of the sex chromosomes during late spermatogenesis. [PDF]
, 2005 Chromosomes are highly organized and compartmentalized in cell nuclei. The analysis of their position is a powerful way to monitor genome organization in different cell types and states.

Effect of zinc on boar sperm liquid storage
Frontiers in Veterinary Science, 2023 Storage and transport of liquid boar sperm for artificial insemination (AI) requires the addition of solutions called extenders, which increase the volume of the ejaculate and help preserve its functional characteristics. Yet, the quality of sperm decreases over time primarily due to the increased production of reactive oxygen species (ROS) that damage

Animals, 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.

Effects of zinc chloride on boar sperm quality during liquid storage at 17°C
Veterinary Medicine and Science, 2023 Objectives The aim of this study was to evaluate the effects of zinc chloride (ZnCl2) at 20, 50, 100, and 200 μg/mL on the quality of seminal plasma‐free boar sperm stored at 17°C for 7 days and to explore the underlying mechanisms.

Artificial insemination with frozen‐thawed boar sperm [PDF]
Molecular Reproduction and Development, 2017 Artificial insemination with frozen‐thawed semen in pigs is not a routine technique; its use is restricted to specific cases, such as preservation of valuable genetic material (germplasm banks), safety strategies in case of natural disasters, long‐distance transport of sperm, and in combination with sex‐sorting.

Effect of an Antioxidant Supplement Combination on Boar Sperm
Animals, 2022 The study was conducted on a commercial pig farm located in Serbia. Thirty Duroc or Landrace breed boars were randomly selected for this study. The experimental group was fed a compound feed with added organic selenium and Oxynat 3D. The antioxidant status parameters of boar seminal plasma were evaluated using a biochemical analyzer and commercial ...
