Phthalates

Avoid — human studies link phthalate exposure in women to diminished ovarian reserve and poorer IVF outcomes; the EU classifies several as reprotoxic Category 1B.
Fertility & hormonal impact
Phthalates are anti-androgenic plasticizers, but in women the reproductive concern is broader. Studies of women undergoing fertility treatment associate higher urinary phthalate metabolites (notably DEHP and its metabolites) with diminished ovarian reserve, fewer retrieved oocytes, lower antral follicle counts, and reduced clinical pregnancy and live-birth rates per cycle. Phthalate exposure has also been linked to higher odds of pregnancy loss in epidemiological cohorts. Mechanistically, phthalates disrupt ovarian steroidogenesis and induce oxidative stress in granulosa cells, which can impair follicle development and oocyte quality. DBP is classified as reprotoxic Category 1B in the EU.
Found in.
Two jurisdictions, two different verdicts.
DEHP, DBP, BBP, and DIBP restricted under REACH Annex XVII. Several classified as Substances of Very High Concern (SVHC). Concentration limits apply in toys and childcare articles.
No federal cosmetic limit; FDA banned certain phthalates in children's toys under CPSIA. DEHP removed voluntarily by many manufacturers after FDA review.
