“…Mounting evidence illustrated that women in Cd-contaminated areas experience irregular periods, difficult pregnancies, early deliveries, and stillbirths [ 6 , 7 ]. Additionally, animal studies also documented that Cd can threaten the reproductive system of female rats (0.09–4.5 mg/kg Cd orally per day) and mice (5–6 mg/kg Cd orally per day), manifesting as a broken ovary structure and disrupted estradiol (E2) secretion, which is responsible for the regular development and homeostasis of the female reproductive system [ 8 , 9 , 10 ]. It is worth noting that the ovarian granulosa cell, as the factory of estrogen production, is one of the targets of Cd in females, in which mitochondrial malfunction, estrogen attenuation, and induced apoptosis were persistent in the presence of Cd exposure [ 11 ].…”
