Abstract

Epigallocatechin gallate (EGCG), the predominant polyphenol in green tea, exerts a spectrum of physiological activities, including antioxidant, anticancer, and anti-inflammatory effects. Emerging research underscores the significance of EGCG in modulating oocyte aging. EGCG can enhance antioxidant defenses, improve mitochondrial functions, and inhibit apoptotic pathways, thereby retarding the aging of oocytes. This review delineates the main molecular features of EGCG and expounds its regulatory mechanisms concerning oocyte aging, enriching the knowledge on the role of EGCG in the amelioration of oocyte aging.

Research summary

The paper discusses the role of EGCG in modulating oocyte aging, which is directly related to the biological processes of aging and longevity. However, while it presents interesting findings regarding the antioxidant and mitochondrial functions of EGCG, the overall contribution appears to be incremental rather than groundbreaking. The focus on oocyte aging is important, but it does not address broader mechanisms of aging or lifespan extension, limiting its impact on the field.
