Impact of Real-life Environmental Exposures on Reproduction: Endocrine-disrupting chemicals, reproductive aging, and menopause.

Narrative review of epidemiological and animal literature without systematic search or meta-analysis

What was done
This narrative review synthesized epidemiological and experimental animal studies examining the associations between environmental endocrine-disrupting chemicals (EDCs)—including phthalates, bisphenols, parabens, per- and poly-fluoroalkyl substances, polychlorinated biphenyls, dioxins, and pesticides—and female reproductive aging, timing of menopause, and menopausal symptoms.
What was found
The abstract reports no quantitative values, hazard ratios, or effect estimates. It reports qualitative associations where exposure to these chemical classes correlates with accelerated reproductive aging, earlier menopausal age compared to the average of 51 years, and more intense menopausal symptoms.
Why it matters
Early menopause increases long-term risks for cardiovascular disease, osteoporosis, and depression. Understanding environmental contributors to accelerated ovarian aging highlights potential modifiable risk factors for women's midlife health.
Limits
The abstract provides no specific study count, human sample sizes, exposure levels, or effect magnitudes. The synthesis relies on a narrative combination of observational human cohorts and animal models, which prevents establishing definitive causality or ruling out residual confounding.
