13 Jul 2022 --- A study by the National Institutes of Health (NIH) suggests that prenatal phthalate exposure is associated with preterm birth. Researchers from Spain also studied the impact of exposure to phthalates during early life on reproductive development and function and found that it influences the timing of pubertal development. Phthalates are synthetic compounds, often called plasticizers, used in common consumer goods including personal care products, food processing and packaging.
