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

The Regulation of Apoptosis in Preantral Ovarian Follicles
Neurosignals, 2000 Less than 1% of ovarian follicles ever mature to ovulation. The remainder undergo atretic degeneration via apoptosis during development. Though the regulation of antral and preovulatory survival has been studied for many years, very little is known about the regulation of survival and development of preantral follicles.

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.

Cytomolecular and In Vitro Toxicity Studies on Bisphenol A Effect on Ovine Granulosa Cells
Veterinary Medicine International, Volume 2026, Issue 1, 2026.Bisphenol A (BPA), an organic environment chemical, has extensive presence in consumer goods and food/feed items. The present study aimed to explore how BPA influenced the viability, proliferation, apoptosis, and steroidogenic activity of ovine ovarian granulosa cells (GCs).

Molecular Reproduction and Development, Volume 92, Issue 12, December 2025.ABSTRACT During recent decades a myriad of approaches have emerged for generating surrogate gametes or achieving in vitro gametogenesis (IVG). The most recent approaches to IVG include the development of increasingly complex culture systems, use of companion cells combined with germ line cells in two‐ or three‐dimensional configurations, derivation of ...

Advanced Science, Volume 12, Issue 38, October 13, 2025.Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.
