BACKGROUND: Environmental chemicals may be associated with endometriosis. No published research has focused on the possible role of perfluorochemicals (PFCs) despite their widespread presence in human tissues. METHODS: We formulated two sam…

BACKGROUND: An equivocal literature exists regarding the relation between persistent organochlorine pollutants (POPs) and endometriosis in women, with differences attributed to methodologies. OBJECTIVES: We assessed the association between …

Benzophenone (BP)-type UV filters are widely used in a variety of personal care products for the protection of skin and hair from UV irradiation. Despite the estrogenic potencies of BP derivatives, few studies have examined the occurrence o…

ObjectiveTo estimate the incidence of endometriosis in an operative cohort of women seeking clinical care and in a matched population cohort to delineate more fully the scope and magnitude of endometriosis in the context of and beyond clini…

Background and Aims: Persistent organic pollutants (POPs) have been associated with endometriosis, though with equivocal results possibly reflecting choice of biospecimen. We sought to assess this ...

Limited study of persistent organochlorine pesticides (OCPs) and endometriosis has been conducted. One hundred women aged 18-40 years who were undergoing laparoscopy provided 20 cm(3) of blood for toxicologic analysis and surgeons completed…

BACKGROUND: Intrauterine environmental exposures have been adversely associated with male reproductive health in contrast to limited investigation of such exposures and female reproductive health. METHODS: To address this research gap, a co…
