p,p'-DDE is a metabolite and degradation product of the organochlorine pesticide DDT. It accumulates in smallmouth buffalo, channel catfish, and largemouth bass as well as sediment in the Huntsville Spring Branch-Indian Creek tributary system surrounding a DDT manufacturing plant where it is considered a persistent organic pollutant (POP). p,p'-DDE inhibits estrogen binding to rainbow trout estrogen receptors (rtERs) with an IC50 value of 8 µM. It induces concentration-dependent secretion of estradiol by granulosa and theca cell co-cultures isolated from porcine ovarian follicles. p,p'-DDE (50-100 µM) also decreases ATP levels, the proportion of sperm with high mitochondrial membrane potential, and motility of human sperm in vitro.
