The impact of mitochondrial dysfunction on ovarian aging

Ovarian aging has become a focal point in current research on female aging and refers to the gradual decline in ovarian function as women age. Numerous factors influence ovarian aging, among which mitochondrial function is one because it plays a crucial role by affecting oocytes and granulosa cells. Mitochondrial deterioration not only leads to a decrease in oocyte quality but also hinders follicle development, further impacting women's reproductive health and fertility.

This review summarizes and integrates research on the impact of mitochondrial function on ovarian aging, outlining the mechanisms by which mitochondria regulate the functions of oocytes and granulosa cells. This study aims to provide potential therapeutic directions to mitigate mitochondrial decline and support female reproductive health. EVIDENCE REVIEW: According to a 2023 study published in Cell, factors such as oxidative stress, mitochondrial dysfunction, chronic inflammation, and telomere shortening collectively drive ovarian aging, directly affecting female fertility. Among these factors, mitochondrial dysfunction plays a key role. This study reviewed literature from databases such as PubMed, Google Scholar, and CNKI, using keywords such as "mitochondrial dysfunction", "decline in oocyte quality and quantity", and "ovarian aging", aiming to summarize current research on the mechanisms of the impact of mitochondrial dysfunction on ovarian aging and provide theoretical support for future exploration of related therapeutic strategies.
