The effects of di (2-ethylhexyl) phthalate (dehp) on lesion development in a mouse model of endometriosis
… the effects of di (2-ethylhexyl) phthalate (DEHP) on lesion development in our mouse model. Our main findings are that, 1) supplementing ovariectomized mice with 100 ng or 1 µg of 17β-estradiol every 4 days is not sufficient for the long term maintenance of endometriotic lesions. However …

The transgenerational effects of Di(2-ethylhexyl) phthalate on female reproduction in mice
Di(2-ethylhexyl) phthalate (DEHP) is a plasticizer used to confer flexibility and stability in common polyvinyl chloride products. DEHP can be found in numerous consumer products and is a ubiquitous chemical. Humans are exposed to DEHP daily due to its widespread use and ability to leach from out …

Mechanisms by which di(2-ethylhexyl) phthalate and mono(2-ethylhexyl) phthalate disrupt ovarian folliculogenesis and steroidogenesis
Di(2-ethylhexyl) phthalate (DEHP) is a synthetic plasticizer used in the manufacturing of common polyvinyl chloride consumer, medical, and building products. Humans are exposed to DEHP on a daily basis because of its high production volumes, incorporation into widely used products, and its ability …

The immediate and long-term consequences of temporary exposure during adulthood to di(2-ethylhexyl) phthalate and diisononyl phthalate on female reproduction
… common phthalates is di(2-ethylhexyl) phthalate (DEHP), with up to 100 million pounds produced within the U.S. each year. DEHP is used as a plasticizer to impart strength and flexibility into products. DEHP can be found in products such as plastic food packaging, clothes, shower curtains, …

The effects of environmentally relevant toxicants on female reproduction and embryo development
… phthalate such as Di (2-ethylhexyl) phthalate (DEHP) and other EDCs have adverse effects on proper embryo development. However, there are limited data on the effects of exposure to relevant phthalate mixtures on preimplantation embryos. In this dissertation, I first examined whether adult …

Changes in Hippocampal Plasticity and HPA Axis Function Following Postnatal Exposure to Di(2-Ethylhexyl) Phthalate in Rats
… there is an associated activation of HPA axis. DEHP was injected in juvenile rats daily from PND 16 – PND 22. Brain tissue samples were analyzed by immunohistochemistry to quantify developing neurons. The Golgi – Cox Impregnation method was used for detailed morphological analyses. Blood samples …

Reproductive function in young Swedish men - Time trend, prenatal and adult exposure to smoking and phthalates
… prenatal exposure to diethylhexyl phthalate (DEHP) and diisononyl phthalate (DiNP) appeared to be associated with decreased semen volume, and exposure to DiNP as well with smaller testicular size. Finally, adult exposure to DEHP and dibutyl phthalate (DBP) were associated with decreased …

Mechanisms underlying establishment and maintenance of pregnancy
… chemicals like di(2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DiNP) are ubiquitous in nature and human exposure to these chemicals is inevitable. The impact of exposure to these phthalates in the establishment and maintenance of pregnancy remains largely unknown. The current …
