Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.

Menopause and vascular endothelial health: Is it all about the oestrogen?

Experimental Physiology, EarlyView.
Abstract Cardiovascular disease (CVD) is a leading cause of mortality in women, and CVD risk is accelerated during the menopause transition. This acceleration has traditionally been attributed to the hallmark decline in oestradiol with menopause. However, the menopause transition is also characterized by changes in other sex hormones that exert effects

Transcriptomic signatures reveal systemic adaptations and immune modulation in response to training and competitive racing in horses

Equine Veterinary Journal, Volume 58, Issue 5, Page 1413-1444, September 2026.
Abstract Background The molecular mechanisms underlying adaptation to physical exertion and racing stress in horses remain incompletely understood. Peripheral blood transcriptomics offers a minimally invasive method to monitor systemic responses to exercise and identify biomarkers of adaptation or overload. Objectives To evaluate transcriptomic changes

Use of equine chorionic gonadotropin in lactating dairy cattle: a rapid review

New Zealand Veterinary Journal, 2022
To use an evidence-based approach to evaluate the available research data on the efficacy of equine chorionic gonadotropin (eCG) to improve reproductive performance of dairy cows when added to oestrus synchronisation programmes for the treatment of cows not detected in oestrus.

Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

Characterization of Lipizzan Horse Population From Lipica Stud Using Molecular and Pedigree Data

Animal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT In this study, we analysed genetic diversity, population structure and inbreeding in the Lipica Stud Farm population by integrating pedigree records, microsatellite (STR) and genome‐wide SNP data generated using the GGP Equine 70K BeadChip. The dataset comprised 233 horses from the Lipica Stud Farm, which served as the reference population for

Embryonic Mediators of Embryo–Uterus Communication, Implantation and Pregnancy

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT Successful reproduction in eutherian mammals requires intimate connections between the embryo and uterus, involving adhesion, attachment and placentation, with or without invasion of the endometrium. The complex dialogue between embryo and uterus involves numerous molecules and pathways.

Induction of follicular luteinization by equine chorionic gonadotropin in cyclic guinea pigs [PDF]

Journal of Zhejiang University-SCIENCE B, 2015
The effects of equine chorionic gonadotropin (eCG) on follicular development and ovulation in cyclic guinea pigs were investigated by histological and immunohistochemical analyses. Three groups of guinea pigs (n=12) were administrated subcutaneously with saline, 20 or 50 IU of eCG, respectively, on cyclic Day 12 (Day 1=vaginal openings).

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

Phytotherapy Research, Volume 40, Issue 8, Page 4880-4897, August 2026.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...
