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 ...

Razvoj in vitro preantralnih folikula u uzgoju s kumulusnim ili granuloznim stanicama. [PDF]

, 2010
Low reproductive effifi ciency in buffalo limits the number of offspring produced during lifespan and thus results in under-exploitation of the superior female genetic material.

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

Serine threonine kinase receptor associated protein regulates early follicle development in the mouse ovary. [PDF]

, 2017
The molecular mechanisms involved in regulating the development of small, gonadotrophin-independent follicles are poorly understood; however, many studies have highlighted an essential role for TGFB ligands.

Zinc Deficiency Disrupts Germ Cell Nest Breakdown During In Vitro Ovary Culture

Molecular Reproduction and Development, Volume 93, Issue 2, February 2026.
ABSTRACT In mammals, the size of the non‐renewable primordial follicle pool is established before or soon after birth. Primordial follicles, each composed of a single oocyte surrounded by somatic cells, are the only source of gametes during the entire reproductive lifespan of the female.

Methods for Equine Preantral Follicles Isolation: Quantitative Aspects

Reproduction in Domestic Animals, 2013
ContentsThe aim of this study was to test the use of mechanical and mechanical‐enzymatic methods, saline solution (SS), and PBS solution for the manipulation and isolation of mare ovarian preantral follicles (PAFs). The ovaries were subjected to mechanical isolation (mixer) alone or in association with enzymatic digestion (collagenase).

TFAM‐Mediated mtDNA Replication is Essential for Developmental Competence of In Vitro Grown Oocytes

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose Mitochondria are essential for oocyte maturation and early embryonic development, supplying ATP and maintaining mitochondrial DNA (mtDNA) integrity. During oogenesis, mtDNA undergoes dramatic amplification, but the mechanisms and functional significance of this process remain unclear. The purpose of this study was to elucidate the role

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 ...

Autoimmune Thyroid Disease and Female Fertility: Clinical Evidence on Ovarian Reserve, Infertility Treatment Outcomes, and Pathophysiology

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
Thyroid autoimmunity may exert a subtle influence on ovarian reserve through complex endocrine and immune mechanisms, with age‐specific variation. Although AMH alterations are observed, their clinical relevance for primary ovarian insufficiency, fertility, and treatment outcomes of assisted reproduction remains unclear, highlighting the need for ...
