Foradori, CD, LR Hinds, WH Hanneman and RJ Handa. 2009. Effects of atrazine on GnRH neuroendocrine function after its withdrawal in the adult female Wistar rat. Biology of Reproduction doi:10.1095/biolreprod.109.077453.
Synopsis by Heather Patisaul, Ph.D.

The common and highly-used herbicide atrazine can act within the brain to disrupt the cascade of hormone signals needed to initiate ovulation, finds a study with rats published online in the journal Biology of Reproduction. Ovulation is a complex process that begins in the brain and ends with the release of eggs from the ovary. This new study finds that exposure to atrazine can interrupt this process but once the exposure ends, normal function resumes in a few days. The results shed new light on the way atrazine affects the female reproductive system and the persistence of these effects when adults are exposed.
