Abstrakt: Although the ovarian reserve is constituted in utero, the literature on the effects of persistent organic pollutants (POPs) during this vulnerable period on the ovarian reserve later in life is limited. We investigated whether cord blood concentrations of POPs were associated with decreased anti-Müllerian hormone (AMH, a marker of the ovarian reserve) levels in girls at the age of 12. We included 239 girls from the French mother-child PELAGIE cohort. POP concentrations of 14 organochlorine pesticides, 17 polychlorinated biphenyls (PCBs), 5 polybrominated diphenyl ethers, and 9 per-polyfluoroalkyl substances were measured on cord blood sampled at birth. During a follow-up study at 12 years old, blood samples were collected to measure AMH levels. Single-exposure associations were examined with multivariable linear regression models adjusted a priori for potential confounders. Stratification on menarche status was also performed. Mixture effects were investigated using quantile g-computation and Bayesian kernel machine regression. Overall, 16 POPs were measured in at least 30% of samples. No significant associations were found in multivariable linear regressions, except for the third tercile of exposure to PCB 180 which was statistically significantly associated with an increase in AMH levels at 12 years old (Tercile 2 v. Tercile 1: 0.13 ng/mL, 95% CI = -0.29, 0.56; Tercile 3 v. Tercile 1: 0.51 ng/mL, 95% CI = 0.02, 0.99). Additionally, in post-menarcheal girls (N = 104) only, the second tercile of p,p'-DDE was statistically significantly associated with decreased AMH levels at 12 years old (Tercile 2 v. Tercile 1: -0.61 ng/mL, 95% CI = -1.16, -0.05, Tercile 3 v. Tercile 1: 0.02 ng/mL, 95% CI = -0.51, 0.54). Both mixture models returned null associations. Despite the limited associations observed in this study, we recommend exploring these associations in larger mother-child cohorts and at older ages.
