Effects of Resveratrol-Loaded Cyclodextrin on the Quality Characteristics of Ram Spermatozoa Following Cryopreservation

Animals
This study investigated the effects of pure and methyl-β-cyclodextrin loaded forms of resveratrol (10 µg/mL, 20 µg/mL, and 40 µg/mL) on ram sperm functions post-thawing. Semen samples were pooled and divided into ten groups: Control, RES10, RES20, RES40,

Mito‐TEMPO Improves Post‐Thaw Quality and Fertilizing Capacity of Rooster Semen Cryopreserved in Beltsville Extender

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Which is more effective in thawing frozen rooster sperm: varying temperature or duration?

Frontiers in Veterinary Science
IntroductionCryopreservation of poultry sperm is crucial for preserving genetic diversity and protecting endangered breeds. Rooster sperm is highly sensitive to cryopreservation due to its high polyunsaturated fatty acid content, making it prone to ...

Limited Utility of a Test‐Yolk Buffer Semen Extender for Preserving Human Semen Parameters for Use in a Diagnostic Setting

Andrology, Volume 14, Issue 6, Page 1701-1711, September 2026.
ABSTRACT Background Identification of a preservation medium that accurately retains semen parameters would be advantageous for men requiring semen analysis by allowing them to produce sperm samples at home rather than on site or even facilitate ‘mail order’ semen analysis.

Comparative assessment of thawing methods for frozen rooster sperm

Frontiers in Veterinary Science
IntroductionCryopreservation, widely used in commercial poultry breeding, often reduces sperm motility, viability, and DNA integrity due to cryopreservation-induced damage.

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Gestational Feed Restriction Induces Differential Expression of Novel Long Non‐Coding RNAs in Offspring Skeletal Muscle

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT This study aimed to investigate how maternal feed restriction at different gestational stages alters the expression of novel long non‐coding RNAs (lncRNAs) in the skeletal muscle of goat offspring. LncRNAs are emerging as important regulators of biological processes, including myogenesis, yet their role in fetal programming remains largely ...

Healthier Herds, Heavier Workloads? The Gendered Time and Resource Implications of Herd Health Management in Kenyan Dairy Systems

Journal of International Development, Volume 38, Issue 6, Page 933-945, August 2026.
ABSTRACT Strategies for sustainable intensification of livestock are critical for food system transformation. In dairying systems, herd health management is among such strategies. Although adoption patterns and productivity gains have been analysed in previous studies, the social implications are still not well understood.

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 211-219, August 2026.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.
