This document provides a basis for the estimation of cancer risk from exposure to di(2­ ethylhexyl)phthalate (DEHP). Epidemiological evidence is uninformative with respect to quantitative estimates of cancer risk to humans from exposure to DEHP. There is evidence that DEHP induces liver tumors in rats and mice by a mode of action common to a class of compounds called “peroxisome proliferators,”...

Although is clear that exposure to high dosage levels of some phthalates delays the onset of puberty in the male rat, it has been hypothesized that low levels of di(2-ethylhexyl) phthalate (DEHP) accelerate puberty by enhancing testicular androgen synthesis. The current study was designed to determine if the dose response to DEHP was nonmonotonic, as hypothesized. Pubertal administration of DEH...

BACKGROUND Di(2-ethylhexyl) phthalate (DEHP) and its metabolites are known to affect lipid metabolism and adipogenesis, mainly by activation of peroxisome proliferator-activated receptors (PPARs). Exposure to DEHP has been linked with testicular impairment and male subfertility. However, the effects of DEHP on female reproductive health and metabolism have not been studied in detail. OBJECTIV...

Measurements of the radiocarbon abundance in 5 samples of bis(2-ethylhexyl) phthalate (DEHP) isolated from Stilton cheese were made by accelerator mass spectrometry (AMS) to determine the fraction of carbon originating from contemporary biogenic sources. DEHP is classified as a “priority hazardous substance” by the European Union, a probable human carcinogen by the United States Environmental P...

The present study was undertaken to determine the reproductive hazards of Di-(2-ethylhexyl)-phthalate (DEHP) on mouse spermatozoa and embryos in vitro and genomic changes in vivo. Direct low-level DEHP exposure (1 μg/ml) on spermatozoa and embryos was investigated by in vitro fertilization (IVF) process, culture of preimplanted embryos in DEHP-supplemented medium and embryo transfer to achieve ...

Phthalates, a class of chemicals used as plasticizers, are economically important due to several industrial applications. Di(2-ethylhexyl)phthalate (DEHP) is the most commonly used phthalate plasticizer, and it has been described as a potent antiandrogen in males. We performed an extensive dose-response study following developmental exposure to DEHP and evaluated the effects on female reproduct...

Di-(2-ethylhexyl) phthalate (DEHP) is an environmental endocrine disrupter. Currently, little is known about neurodevelopmental toxicity of DEHP in wildlife and humans. The present study investigated the effects of DEHP, focusing on the changes in the behavior of offspring mice at the ages of 6 and 12w, respectively, following utero and lactational exposure to DEHP (10, 50, and 200mg/kg/d) from...

BACKGROUND There is an ongoing discussion about the risks of di(2-ethylhexyl) phthalate (DEHP) exposure for the general population as well as for specific subgroups in various medical settings. Haemodialysis patients certainly belong to the group with the highest exposure taking into account the repeated treatments over a long period of time. Many studies have shown that DEHP metabolites are mo...

In animal studies using oral dosing for short periods, di (2-ethylhexyl) phthalate (DEHP) is well known for its reproductive toxicity, especially for its testicular toxicity. However, extending the period of DEHP exposure in prepubertal rats resulted in significant increases in testosterone. This suggests that the reproductive effect of DEHP might be associated with the timing and the term of e...

Phthalates are ubiquitous environmental contaminants because of their use in plastics and other common consumer products. Di-(2-ethylhexyl) phthalate (DEHP) is the most abundant phthalate and it impairs fertility by acting as an endocrine disruptor. The aim of the present study was to analyze the effects of in vitro acute exposure to DEHP on oocyte maturation, energy and oxidative status in the...
