A frequently used pesticide has shown to jump-start puberty in boys, a new study finds.

The study was presented at the annual Endocrine Society meeting in Orlando, Florida, held from Saturday to Tuesday.

Researchers at Zhejiang University in Hangzhou, Chinam monitored increased levels of two hormones that stimulate testosterone production in Chinese boys exposed to pyrethroids, Agence France-Presse reports.



Pyrethroids are a type of pesticide found in almost a third of insecticides globally, are present in the soil, air and water and found in domestic products like mosquito repellent and head lice shampoo.

Boys with an increase of pyrethroid in their system were associated with an increase in luteinizing hormone and follicle-stimulating hormone.

AFP notes that the chemical is known to have toxic effects on the nervous system, with children susceptible to developing cognitive defects.
