Ovarian features in white-tailed deer (Odocoileus virginianus) fawns and does.

PLoS ONE, 2017
The knowledge about ovarian reserve is essential to determine the reproductive potential and to improve the methods of fertility control for overpopulated species, such as white-tailed deer (Odocoileus virginianus). The goal of this study was to evaluate

Salidroside Ameliorates Polycystic Ovary Syndrome in Mice by Regulating the AKT/NF‐κB/NLRP3‐HAS2 Axis

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Salidroside ameliorates PCOS via inhibiting the ROS‐AKT/NF‐κB axis and suppressing NLRP3 inflammasome activation. It disrupts the NLRP3–LAP‐TGFβ1 interaction to block TGF‐β‐SMAD2/3 signaling and consequent ovarian fibrosis. Together with hyaluronan synthase 2 (HAS2) downregulation, these effects alleviate inflammation and hyaluronan overaccumulation ...

Vitamin D3 Regulates Follicular Development and Intrafollicular Vitamin D Biosynthesis and Signaling in the Primate Ovary

Frontiers in Physiology, 2018
There is an increasing recognition that vitamin D plays important roles in female reproduction. Recent studies demonstrated that 1α,25-dihydroxyvitamin D3 (VD3), the biologically active form of vitamin D, improved ovarian follicle survival and growth in ...

Growth Differentiation Factor 9 Supplementation Restores the Lipopolysaccharide‐Induced Negative Effects on Bovine Oocyte Developmental Competence

Molecular Reproduction and Development, Volume 93, Issue 4, April 2026.
ABSTRACT Growth differentiation factor 9 (GDF9) plays a key role in enhancing developmental competence and blastocyst yield during in vitro maturation (IVM). This study investigated whether GDF9 could counteract the harmful effects of lipopolysaccharide (LPS), a gram‐negative bacterial component, on bovine in vitro embryo production, while also ...

Expressions of Kisspeptin System and Ki‐67 in the Reproductive Tissues of Cyclic Bitches

Reproduction in Domestic Animals, Volume 61, Issue 4, April 2026.
ABSTRACT Kisspeptin is a peptide that plays a pivotal role in the central regulation of gonadotropins. It is regarded as a key regulator of reproductive processes, including follicular and luteal development and endometrial remodelling. The objective of this study was to investigate the expression of KISS1, its receptor KISS1R and the proliferation ...

IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

Advanced Science, Volume 13, Issue 18, 27 March 2026.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

Isolation and characterization of preantral follicles from foetal bovine ovaries [PDF]

Veterinary Quarterly, 1994
A simple, mechanical method is described for the isolation of preantral follicles from bovine foetuses of 220-280 days of gestation. On average, 2918 + 621 (s.d.) preantral follicles were isolated per ovary. The isolated preantral follicles were characterized on the basis of the morphological appearance of the surrounding granulosa cells, the number of

Sphingosine 1-phosphate promotes activation of aprine preantral follicle in vitro

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
This study describes the effect of sphingosine 1-phosphate (S1P) for development of preantral follicle, therefore the activation and follicular viability of caprine follicles cultured in vitro.

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

Advanced Science, Volume 13, Issue 17, 23 March 2026.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Vitrification affects the expression of matrix metalloproteinases and their tissue inhibitors of mouse ovarian tissue

Iranian Journal of Reproductive Medicine, 2016
Background: One of the most major obstacles of ovarian tissue vitrification is suboptimal developmental competence of follicles. Matrix metalloproteinases 2 (MMP-2) and 9 (MMP-9) and their tissue inhibitors TIMP-1 and TIMP-2 are involved in the ...
