How does BPA in clothing affect fertility?

Bisphenol A (BPA) is an endocrine-disrupting chemical commonly used in the production of synthetic textiles, particularly as a component of polyester manufacturing and textile dyes. BPA mimics estrogen in the body, binding to estrogen receptors and disrupting the delicate hormonal balance required for reproduction. In women, BPA exposure has been linked to reduced oocyte maturation, meaning eggs may not develop properly before ovulation, lowering the chances of successful fertilization.

In men, BPA's estrogenic activity can suppress testosterone production and interfere with sperm development. Studies have found associations between elevated BPA levels and reduced sperm count, decreased motility, and abnormal sperm morphology. Because BPA is lipophilic, it readily leaches from synthetic fabrics when exposed to sweat and body heat, making activewear and close-fitting garments particularly significant sources of exposure during exercise.

Choosing clothing free from BPA and other endocrine disruptors is especially important for anyone trying to conceive. Look for OEKO-TEX Standard 100 or GOTS-certified garments, which are tested for harmful chemical residues. ONDU curates brands like Tripulse and Reprise Activewear that use plant-based fabrics processed without BPA, phthalates, or other hormone-disrupting chemicals.
