TCPy or 3,5,6-trichloro-2-pyridinol is a metabolite of chlorpyrifos and chlorpyrifos-methyl, both organophosphate insecticides. A study in Massachusetts reported a correlation between exposure to TCPy and lower testosterone levels in men.[1] According to this source, exposure is "widespread" and of "potential public health importance".
