University of Missouri researchers have discovered that an oil and natural gas drilling technique called hydraulic fracturing uses chemicals that can disrupt the body's hormones. The researchers found that the endocrine-disrupting chemicals used in the process could interfere with a class of hormones that includes testosterone and estrogen. The findings were published in the journal Endocrinology.
