Can di-butyl phthalate from plastics and packaging affect male reproductive hormones?
Some Concern
What's actually in it
Di-butyl phthalate (DBP) isomers are found in food packaging, adhesives, printing inks, nail polish, and some pharmaceuticals. They enter your body through food, skin contact, and inhalation. In men, these phthalates can interfere with testosterone and other reproductive hormones.
What the research says
A 2026 systematic review and dose-response meta-analysis in Environ Toxicol Pharmacol examined the link between urinary DBP metabolites and reproductive hormones in adult men. The review found that higher DBP exposure was associated with changes in reproductive hormone levels, with a clear dose-response relationship.
Disrupted reproductive hormones in men can lead to lower sperm quality, reduced fertility, and other health effects.
Reduce phthalate exposure by choosing fragrance-free products, avoiding PVC plastics, and storing food in glass. Check personal care products for dibutyl phthalate or DBP on the label.
