Abstract
PURPOSE OF REVIEW: This review seeks to evaluate the impact of environmental exposures on the menstrual cycle length detailing timing of exposure on pathophysiology. RECENT FINDINGS: Recent literature has examined the relationship between menstrual cycle length and environmental exposures including air pollutants, parabens, and polybrominated biphenyls. SUMMARY: Research is limited but suggest importance of further research in evaluating environmental exposures and menstrual cycle length.
