Mitochondrial Function and Antioxidant Strategies in Oocyte Development
Summary
Mitochondria are central to oocyte maturation and early embryogenesis, supplying adenosine triphosphate (ATP), regulating calcium homeostasis and controlling redox balance. Within the maturing oocyte, mitochondrial biogenesis, dynamics and distribution ensure adequate energy for meiotic spindle formation and chromosomal segregation. However, reactive oxygen species (ROS) generated during oxidative phosphorylation can damage mitochondrial DNA, proteins and lipids, leading to loss of membrane potential, reduced ATP output and meiotic errors. These effects become more pronounced with maternal ageing, as oocytes accumulate mitochondrial dysfunction and oxidative stress, compromising developmental competence and fertility. Antioxidant strategies seek to restore redox homeostasis by enhancing endogenous defence systems or by supplementing exogenous compounds. Coenzyme Q10 (CoQ10), melatonin, resveratrol and natural polyphenols have been investigated for their capacity to stabilise mitochondrial membrane potential, quench ROS and promote mitochondrial biogenesis. Preclinical studies report improvements in spindle integrity, ATP synthesis and genomic stability, while clinical interventions have demonstrated increases in retrieved oocyte numbers, high-quality embryos and pregnancy rates. Despite promising outcomes, optimisation of dosing regimens, timing of administration and long-term safety remain active areas of research. Advances in targeted mitochondrial delivery and combination therapies are poised to refine assisted reproductive technologies and to develop therapeutic strategies for age-related ovarian decline.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
