This article is related to the reproductive cycle of Mohawk girls, specifically menstruation. Menarche is the first menstruation of a young woman. Few studies particularly target toxicant effects on human sexual maturation. The article studies girls of the Mohawk Nation between 10 and 16.9 years of age. Attainment of menses (menarche) was assessed as present or absent at the time of the interview. Congener-specific PCB analysis was available, and all 16 PCB congeners detected in >50% of the sample were included in analyses. The median age of menarch was correlated between the toxicants detected. Conclusion: The attainment of menarche could be hastened by adding toxicants, the theory of earlier menses could be an environmental cause.
