In a split-litter design experiment, boars were exposed orally three times weekly to 300 mg/kg of di(2-ethylhexyl) phthalate (DEHP) between 3 and 7 weeks of age. Post-puberty, i.e. at 6 months of age the effects on endocrinology and mating behavior were examined. The response to stimulation with a synthetic GnRH-analogue at 9 months of age resulted initially in lower concentration of LH in the exposed animals, compared to the control animals. We did not find any effects of DEHP on the mating behavior. Also, the effects of DEHP during the treatment period on the plasma concentrations of testosterone, oestradiol and LH were examined. During the exposure period there was a transient decrease in plasma concentrations of LH in the control group, which did not occur in the boars exposed to DEHR The data suggest that DEHP in low repeated oral doses causes lasting effects on the hypothalamus-pituitary-gonadal axis.
