Plastic Chemical Phthalate Found to Damage Egg Cell DNA, Affect Fertility: Study

A recent study conducted by researchers from Harvard Medical School has revealed that phthalates, common plastic additives, can damage egg cell DNA, impacting fertility. The research focused on benzyl butyl phthalate (BBP), a type of phthalate used to increase plastic flexibility and durability, which is present in food packaging, hygiene products, and children’s toys.

Using roundworms as a model, the study found that BBP exposure caused DNA breaks in egg cells, leading to changes in chromosome numbers and a decline in egg cell quality. Roundworms were chosen due to their similar metabolism to mammals in processing BBP, with researchers noting that the effects observed were consistent with phthalate exposure levels found in humans.

The findings point to potential reproductive risks associated with phthalate exposure in everyday items. As phthalates can alter genetic material within egg cells, the study suggests a broader implication for human fertility. This research highlights the need for further studies on the long-term effects of plastic additives on reproductive health and genetic stability.
