Associations Between Potential Exposure Sources and Urinary Phthalate Concentrations Among Couples Undergoing Infertility Treatment

摘要: Phthalates have been implicated as reproductive toxicants in animal models and in human populations. This study examined associations between potential exposure sources and urinary phthalate concentrations among couples undergoing infertility treatment. Women (n= 56) and their male partners (n= 43) undergoing in vitro fertilization (IVF) were enrolled in a prospective cohort investigation of environmental chemicals and IVF outcomes at an academic medical center. On the day of oocyte retrieval, participants provided urine samples and completed questionnaires detailing use of personal care products (PCPs), and consumption of medications, foods, and beverages in the preceding 24-hours. Urine was analyzed for MEP, MBP, MPP, MHxP, MEHP, MEHHP, MECPP, MiNP, MiDP, MCHP, and MBzP, via liquid chromatography-tandem mass spectrometry. We employed principal component analysis (PCA) to …
