This study found that eight elements (As, Cu, Se, Sr, V, Zn, Cr, Ca) in follicular fluid were positively correlated with polycystic ovary syndrome (PCOS), while Mg was not related. The OPLS models of follicle-stimulating hormone (FSH) and anti-Mullerian hormone (AMH) with relevant elements showed that Mg, Zn, Fe, Se, and V had a more significant effect on FSH and that As, Se, V, Cu, and Zn were positively correlated with AMH. Further analysis indicated that FSH and Mg were protective factors against PCOS, and the associations between the five elements and PCOS incidence were mediated by AMH. Changes in hormone levels between multielement coexposure and PCOS development suggest that FSH and Mg are protective against PCOS, while female exposure to As, Se, V, Cu, and Zn may affect PCOS progression by perturbing AMH levels.
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among reproductive-aged women. Follicular fluid quality affects early embryonic development and multiple stages of pregnancy. This study measured 12 elements in follicular fluid and 5 blood hormones, aiming to identify the associations between multielement concentrations, as well as blood hormone levels, and PCOS to investigate the interference of multielement coexposure on PCOS and examine the potential roles of hormones. Eight elements (As, Cu, Se, Sr, V, Zn, Cr, Ca), but not Mg, showed a positive dose-effect relationship with PCOS. The OPLS models of follicle-stimulating hormone (FSH) and anti-Mullerian hormone (AMH) with relevant elements showed that Mg, Zn, Fe, Se, and V had a more significant effect on FSH and that As, Se, V, Cu, and Zn were positively correlated with AMH (VIP > 1). Further analysis indicated a synergistic effect for FSH and Mg, both of which were protective factors against PCOS; the associations between the five elements and PCOS incidence were mediated by AMH. Changes in hormone levels between multielement coexposure and PCOS development suggest that FSH and Mg are protective against PCOS; female exposure to As, Se, V, Cu, and Zn may affect PCOS progression by perturbing AMH levels.
