Abstract

Fuel fine particulate matter (FPM) is an important component of ambient pollution, has wide biological activity, and can cause a variety of diseases. Epidemiological studies have reported that FPM can decrease human fertility rates, retard embryonic growth, cause adverse effects on pregnancy outcomes, and result in male reproductive damage. However, the effects of FPM on female ovary function and associated mechanisms are still unclear. In this research, different concentrations of gasoline and diesel FPM were chosen to treat female mice in vivo. Fuel FPM can significantly inhibit ovarian function and follicle maturation. The hypothalamus–pituitary–ovary axis was inhibited significantly, with an increase in follicle-stimulating hormone and luteinizing hormone levels and a decrease in estradiol levels, as well as ovary weight loss, which was similar to the symptoms of premature ovarian failure in humans. Fuel FPM can induce the accumulation of copper and lead in the ovary and decrease the levels of zinc, m...
