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.

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 ...

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

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.

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

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 ...

The Role of Anethole in Reproductive Physiology and In Vitro Biotechnologies—A Review
Reproduction in Domestic Animals, Volume 61, Issue 1, January 2026.ABSTRACT In vitro reproductive biotechnologies show promise for fertility preservation but still face challenges, including oxidative stress from high oxygen tension, which impairs cell viability and development. Antioxidants have been widely explored to attenuate oxidative stress during culture.
