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,

Cryopreservation of Sperm: Effects on Chromatin and Strategies to Prevent Them

, 2019
Cryopreservation is a technique that can keep sperm alive indefinitely, enabling the conservation of male fertility. It involves the cooling of semen samples and their storage at −196 °C in liquid nitrogen.

A Low Concentration of a Sustainably Obtained Blueberry Extract Improves the Post‐Thawing Motility of Cryopreserved Bull Spermatozoa

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Natural extracts could improve sperm storage and artificial insemination (AI). This study, for the first time, evaluates the suitability of a blueberry extract (Vaccinium corymbosum), obtained from pomace using a sustainable methodology, as a supplement for bull semen extenders.

Frozen Boar Semen Can Be Successfully Stored at −80°C, Reducing Need for LN2 Storage Containers

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT This study explores alternative freezing approaches aimed at reducing or avoiding the use of liquid nitrogen (LN2) to store boar semen. Sperm‐rich fractions from three boars were pooled and frozen in 0.25‐ and 0.5‐mL straws using four different protocols: a conventional method (Control; LN2 vapours followed by immersion and storage in LN2 ...

Effects of Sucrose and Trehalose Supplementation on Zebrafish (Danio rerio) Sperm Quality During Cold Storage

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT This study evaluated the effect of disaccharide supplementation on zebrafish sperm stored at 5°C for 24 h. Seven pooled replicates from 60 broodfish were used. Semen samples were initially cooled and, after 1 h, supplemented with either HBSS (E‐C), Sucrose 0.13M (E‐S13), Trehalose 0.13M (E‐T13) or Trehalose 0.26M (E‐T26).

Comparative Susceptibility of Donkey and Horse Sperm to Liquid‐Storage Temperature

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Preservation protocols for donkey sperm are based on those developed for horses, despite potential interspecific differences in cooling tolerance. This study compared horse and donkey sperm during long‐term storage at 5°C and 17°C. Ejaculates from four stallions and four jacks (n = 16) were centrifuged, resuspended in skimmed milk‐based ...

Characterization of Cytokines in Donkey Follicular Fluid and Seminal Plasma: A Pilot Study

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Post‐breeding endometrial inflammation is a well‐known physiological response in jennies, especially after artificial insemination with frozen–thawed sperm. Bioactive molecules present in reproductive fluids, including cytokines, may contribute to regulating these immune processes. The aim of this study was to characterize the cytokine profile
