PFAS Are Messing With Girls' Puberty and Hormones

Girls exposed to PFAS before birth and during adolescence show changes in puberty timing and hormone levels.
From the Womb Through Puberty
A 2026 study in Environ Res followed girls from the Sheyang Mini Birth Cohort and measured their PFAS exposure at two points: prenatally and during adolescence. Both exposure windows were associated with changes in pubertal development and endocrine hormone levels.
PFAS don't just affect girls at one point in time. Prenatal exposure sets the stage. Then ongoing exposure during adolescence compounds the disruption. The chemicals interfere with the delicate hormonal cascade that controls when and how puberty unfolds.
Why Early Puberty Matters
Early puberty in girls is linked to higher risks of breast cancer, depression, eating disorders, and metabolic problems later in life. If PFAS are pushing puberty earlier or altering hormone levels during adolescence, the health effects ripple out for decades.
What You Can Do
Reduce PFAS exposure for the whole family: filter your water, avoid nonstick cookware, skip stain-resistant treatments, and choose PFAS-free products. These steps matter from pregnancy through your daughter's teenage years. Browse non-toxic baby products for safer alternatives.
