Review spotlights fisetin’s reproductive potential in mammals

Version 1

A new review in Veterinary Sciences pulls together the emerging evidence on fisetin, a plant flavonoid found in foods such as strawberries, and its possible role in mammalian reproductive health. The paper, published in May 2026 by Yuehua Chen, Xiaogang Huang, and Zhihong Zhao, argues that fisetin’s antioxidant, anti-inflammatory, anti-apoptotic, and anti-aging effects may help protect both female and male reproductive tissues, with potential relevance for gonadal function, endocrine regulation, and the reproductive microenvironment. The authors also flag a key limitation: most of the evidence remains preclinical, and fisetin’s low bioavailability could complicate translation into clinical or production settings. (mdpi.com)

Why it matters: For veterinary professionals, the review is less about a practice-changing intervention today and more about where reproductive and longevity research may be heading. The underlying literature includes rodent and livestock-adjacent models suggesting fisetin may improve ovarian aging markers, endocrine function, and embryo yield in mice, while separate rat work found improved sperm parameters and reduced oxidative stress after testicular ischemia-reperfusion injury, especially when fisetin was paired with quercetin. Still, that evidence is early-stage, species-limited, and not yet supported by clinical data in companion animals or food animals, so any use in veterinary contexts would remain exploratory.

What to watch: Watch for pharmacokinetic work in target veterinary species, better formulation strategies to address bioavailability, and any controlled animal studies that move fisetin from mechanism-heavy promise toward usable reproductive applications. (mdpi.com)
