Bisphenols and follicle function in farm species

Area of Science:

• Reproductive Toxicology
• Endocrinology
• Environmental Health

Background:

• Bisphenols are widespread environmental contaminants impacting human and animal health.
• Growing evidence links bisphenol exposure to disruptions in ovarian function.

Purpose of the Study:

• To review the effects of bisphenols on ovarian follicle physiology in domestic animals (bovine, ovine, porcine).
• To compare findings with human and rodent data.
• To explore the influence of metabolic status on bisphenol-induced ovarian toxicity.

Main Methods:

• Literature review synthesizing studies on bisphenols and ovarian function in domestic species.
• Analysis of bisphenol structures, exposure routes, and metabolic pathways.
• Summary of mechanisms of action on follicular cells.

Main Results:

• Bisphenols alter key ovarian processes including folliculogenesis, steroidogenesis, granulosa cell viability, oocyte maturation, and embryo development.
• Effects vary based on bisphenol type, dose, duration, and model.
• Animal metabolic status modulates ovarian response to bisphenols via receptor interactions (ERs, TR, GR, PPARs).

Conclusions:

• Bisphenols pose a reproductive risk to livestock, with metabolic status as a key factor.
• Further research integrating reproductive and metabolic endpoints is crucial for risk assessment.
• Understanding these interactions supports sustainable animal production.
