Disruption of rat testis development following combined in utero exposure to the phytoestrogen genistein and antiandrogenic plasticizer di-(2-ethylhexyl) phthalate.

Fetal exposure to environmental endocrine disruptors (EDs) is thought to contribute to reported idiopathic increases in adult male reproductive abnormalities. Although humans are exposed to myriad EDs from conception to adulthood, few studies have evaluated the effects of combined EDs on male reproduction. In the present study, we demonstrate that simultaneous gestational exposure to the phytoestrogen genistein and the antiandrogenic plasticizer di-(2-ethyhexyl) phthalate (DEHP) induces long-term alterations in testis development and function.
