A well-known long-term effect of oncological treatment is premature ovarian insufficiency. Another critical but sometimes overlooked organ at risk in female cancer survivors is the uterus. This review focuses on the impact of radiotherapy on uterine physiology, highlighting key issues such as the development of fibrosis and loss of elasticity, vascular damage, and hormonal disruption, all of which can compromise uterine function. These changes can negatively impact fertility and pregnancy outcomes, such as miscarriage, preterm birth, and low birth weight. Limited evidence is also available suggesting that radiotherapy may affect endometrial receptivity and contribute to abnormal placentation. We conclude by discussing strategies aimed at mitigating the damage caused by radiotherapy, such as fertility-preserving treatments and hormonal interventions.

Epidemiologic and animal studies highlight inconsistent yet concerning associations between PFAS exposure and semen parameters, as well as altered gene expression and DNA methylation patterns. Moreover, PFAS exposure during critical windows of development has been linked to differential impacts on male versus female pubertal development, cognitive outcomes, and reproductive physiology, emphasizing the complexity of PFAS interactions. This comprehensive analysis highlights the need for continued research into the mechanisms by which PFASs influence reproductive health and development with potential implications for sperm epigenetics.

BPA was positively associated with endometriosis in four out of seven studies. Phthalates were associated with a greater odds of endometriosis in five studies, and with a reduced odds in one study, while three studies found no association with endometriosis.

This review synthesizes in vivo, in vitro, and epidemiological findings about the effects of endocrine-disrupting chemicals (EDCs), specifically heavy metals and perfluoroalkyl and polyfluoroalkyl substances (PFAS) on female reproductive aging. Most in vivo and in vitro studies have demonstrated that heavy metals alter ovarian morphology, folliculogenesis, and steroidogenesis. Evidence regarding the effects of PFAS is limited and inconsistent. Epidemiological studies have consistently shown that heavy metals are associated with a higher risk of diminished ovarian reserve (indicated by decreased anti-Müllerian hormone) and earlier menopause, with limited findings regarding reproductive hormone changes. PFAS exposure has been associated with decreased estradiol and earlier menopause but not significantly with ovarian reserve.
