Effects of riboflavin on boar sperm motility, sperm quality, enzyme activity and antioxidant status during cryopreservation

Veterinary Medicine and Science, 2022
Objectives This study was conducted to evaluate the effect of adding riboflavin to boar sperm freezing extender on the challenge of cryopreservation. Methods Different concentrations (0, 5, 10, 15, 20 or 25 μM) of riboflavin were added to the freezing ...

Histological Findings in Testes of Baboons (Papio spp.) and Dwarf Bucks (Capra hircus) Subject to Repeated Immunisation Against GnRH

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Long‐term repeated immunisation against GnRH resulted in the absence of active spermatogenesis and may lead to irreversible infertility in dwarf bucks and baboons. Histological examination revealed a marked reduction of the seminiferous tubular lumen, complete depletion of germ cells, germ cell vacuolization and tubular hyalinization.

Genome‐Wide Characterization of Heterozygosity‐Rich Regions in Kazakh Native Sheep Breeds

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Heterozygosity‐rich regions (HRR) are genomic segments characterized by high heterozygosity that may arise from admixture, introgression, or balancing selection and may harbor loci associated with adaptation and fitness‐related traits. This study aimed to characterize HRR patterns in five Kazakh sheep breeds using a publicly available ...

Myo-inositol improves the viability of boar sperm during liquid storage

Frontiers in Veterinary Science, 2023
IntroductionLiquid preservation of boar semen is a highly preferred method for semen preservation in pig production. However, oxidative stress is the main challenge during the liquid preservation of boar semen in a time dependent manner.

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, Volume 14, Issue 7, Page 2166-2179, October 2026.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Reduced glutathione and cysteine hydrochloride on crossbred bull semen [PDF]

, 2012
Over the last few years, good quality freezable semen was not utilized effectively due to less knowledge about the freezability of semen. One reason is the lack of sufficient antioxidants in the seminal plasma and semen extender.

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

Andrology, Volume 14, Issue 7, Page 2207-2220, October 2026.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Seminal Extracellular Vesicles as Molecular Modulators of Male Reproductive Function

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Extracellular vesicles (sEVs) contained in seminal plasma (SP) maintain, in concert with free SP‐components (proteins, hormones, cytokines, metabolites and antioxidants) under an endocrine umbrella the functional in vivo homeostasis of ejaculated spermatozoa. The sEVs define a generic mixture of nanovesicles delivered by male epithelial cells,

Differentially expressed miRNA Cargo From Boar Seminal Extracellular Vesicles Is Linked With Motility Quality in AI Doses

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Sperm motility is a key parameter for male selection and is closely linked to male fertility status. miRNAs have been proposed as fertility biomarkers, and their regulatory effects on sperm motility have been previously investigated. In the present study, the miRNA cargo from three different sources, seminal extracellular vesicles, free ...
