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 ...

Comparative study on the in vitro development of caprine and bovine preantral follicles

, 2013
The present study aimed to evaluate the effect of the addition of IGF-1 to the in vitro culture (IVC) medium on the development of caprine and bovine preantral follicles ≥150μm in diameter. Caprine and bovine preantral follicles were cultured for 18 days

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

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 ...

FOLLICLE POPULATIONS IN MARE OVARIES: FROM PREANTRAL TO PREOVULATORY FOLLICLES

Enciclopédia Biosfera, 2015
The purpose of this study was to describe morphological and quantitative aspects of preantral and antral follicles in the equine ovary. Six ovaries were collected from necropsied mares and sliced lengthwise parallel to the ovulation fossa. The slices were fixed and processed for histological evaluation under light microscopy.

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.

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 ...

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 ...

The physiological status of the ovarian donor affects the in-vitro development of isolated bovine preantral follicles

, 1994
peer reviewedDescribed in the present paper is the effect of the physiological status of the ovarian donor on the development of isolated bovine preantral follicles during 5 d of culture. The preantral follicles were isolated mechanically from ovaries of

Evaluating Potential Effects of Chamomile (Matricaria chamomilla L.) in Polycystic Ovary Syndrome: A Systematic Review and Meta‐Analysis

Food Science &Nutrition, Volume 14, Issue 3, March 2026.
Chamomile contains different bioactive agents such as flavonoids and phytosterols with potential anti‐inflammatory, antioxidant, analgesic, antispasmodic, and antitumor characteristics. According to our findings, animal studies have demonstrated the potential benefits of Chamomile consumption in the treatment of PCOS. In contrast, human studies yielded
