Are you currently exposed to phthalates on a regular basis? Were you exposed during early developmental stages—for example, through maternal exposure such as a mother working in a hair salon while pregnant? Have you noticed symptom improvement after reducing phthalate exposure?
Higher phthalate levels have been associated with a two-fold increase in the rate of endometriosis. Phthalates are present in almost anything fragranced and are widely used in soft plastics, vinyl, cleaning products, nail polish, and perfumes. As early as 2002, environmental groups reported that over 70% of personal care products contained phthalates. Today, according to the Environmental Protection Agency, more than 470 million pounds of phthalates are produced each year.
Phthalates are now officially recognised as reproductive toxins throughout both the European Union and the United States. Animal studies show that rats given high doses of certain phthalates stopped ovulating altogether. Phthalates reduce oestrogen production by ovarian follicles—oestrogen being one of the primary drivers of follicle growth and egg development in both animals and humans. Suppression of oestrogen by follicle cells would be expected to impair follicle growth, helping explain why women with endometriosis often exhibit significantly higher phthalate levels than those without the condition.
Potential sources of exposure are extensive. Plastics can leach into food, particularly when food is packaged while hot or stored in plastic for long periods. Personal care products are a major contributor, including cosmetics, hair products, lotions, infant care products, medications, medical devices, nail polish, and perfumes.
Vinyl products are another source, such as shower curtains, flooring, wallpapers, blinds, diaper mats, rain gear, inflatable mattresses, school supplies, car interiors, and yoga mats. Additional exposures may come from air fresheners, electronics, plastic jewellery, sex toys, and children’s toys.
Given their prevalence and biological impact, understanding and minimising phthalate exposure is an important consideration in hormone and reproductive health.
