Ameliorative Effect of Chitosan Complex on Miniature Pig Sperm Cryopreservation
Journal of Animal Reproduction and Biotechnology, 2018 Cryopreservation is mainly used for preservation of boar sperm. However, this method stresses the sperm by reactive oxygen species (ROS), and the conception rate and the litter size are not more efficient than the liquid preservation of spermatozoa ...

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.

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.

Temperature Elevation during Semen Delivery Deteriorates Boar Sperm Quality by Promoting Apoptosis
Animals, 2023 Semen delivery practice is crucial to the efficiency of artificial insemination using high-quality boar sperm. The present study aimed to evaluate the effect of a common semen delivery method, a Styrofoam box, under elevated temperatures on boar sperm ...

Recent development in freezing strategies of pig semen-A review
Indian Journal of Animal Sciences, 2022 Of late studies on frozen thawed boar semen have dramatically improved boar semen cryopreservation technique, albeit the commercial application of cryopreserved boar semen has not yet been popular. Some studies claimed successful fertility/ fertilization

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