Traffic-related air pollution has been linked to higher risks of infertility and miscarriage. We evaluated whether folate intake modified the relationship between air pollution and livebirth among women using assisted reproductive technolog…

Bisphenol A (BPA) is a widely used chemical that has been detected in follicular fluid and associated with adverse reproductive effects. Granulosa cells have an important role in follicular growth and oocyte maturation, however, little is k…

BACKGROUND: We have previously investigated whether urinary concentrations of bisphenol A (BPA), parabens, and phthalate metabolites were individually associated with reproductive outcomes among women undergoing in vitro fertilization (IVF)…

BACKGROUND: Phenols and phthalates are potential endocrine disrupting chemicals (EDCs) that are associated with adverse health outcomes. These EDCs dysregulate a number of biomolecules and pathways, including microRNAs. MicroRNAs can be car…

IMPORTANCE: Animal experiments suggest that ingestion of pesticide mixtures at environmentally relevant concentrations decreases the number of live-born offspring. Whether the same is true in humans is unknown. OBJECTIVE: To examine the as…

BACKGROUND: While overt thyroid disease is a well known risk factor for infertility, the potential consequences of mild thyroid dysfunction or thyroid autoimmunity remain unknown. Experimental studies suggest a considerable role for thyroid…

Encapsulated microRNAs (i.e., miRNAs within the extracellular vesicles, i.e., EV-miRNAs) have been detected in follicular fluid in both animal and human studies and different profiles have been associated with IVF cycle characteristics. How…

BACKGROUND: Some dietary factors have been linked to outcomes of infertility treatment with assisted reproductive technology (ART), but the role of intake of meats and other protein-rich foods remains unclear. OBJECTIVE: The aim of this ma…

OBJECTIVE: To evaluate whether urinary concentrations of organophosphate flame retardant (PFR) metabolites are associated with pregnancy loss among women conceiving with assisted reproductive technology (ART). DESIGN: Prospective preconcep…

BACKGROUND: The Environment and Reproductive Health (EARTH) Study is an ongoing prospective preconception cohort designed to investigate the impact of environmental, nutritional, and lifestyle factors among both women and men on fertility a…

BACKGROUND: Subfertile women are at increased risk of glucose intolerance in pregnancy. Based on epidemiologic studies, exposure to certain phthalates is associated with diabetes, elevated glucose, and increased insulin resistance. OBJECTI…

Phthalates are a class of chemicals found in a large variety of consumer products. Available experimental and limited human data show adverse effects of some phthalates on ovarian function, which has raised concerns regarding potential effe…

OBJECTIVE: To study whether maternal intake of beverage type affects IVF outcomes. DESIGN: A prospective study. SETTING: Tertiary, university-affiliated center. PATIENT(S): Three hundred forty women undergoing IVF from 2014 through 2016 …

STUDY QUESTION: Does bisphenol-A (BPA) affect gene expression in human membrana granulosa cells (MGC)? SUMMARY ANSWER: In vitro, short exposure to supra-physiological concentrations of BPA alters human MGC gene expression. WHAT IS KNOWN A…

BACKGROUND: Cigarette smoking has been associated with worse infertility treatment outcomes, yet some studies have found null or inconsistent results. METHODS: We followed 225 couples who underwent 354 fresh non-donor assisted reproductive…

PURPOSE: The purpose of this study is to determine the profile of extracellular microRNAs (exmiRNAs) in follicular fluid (FF) and explore their association with fertilization potential and embryo quality. METHODS: We collected FF from sing…

ObjectivesTo explore whether work schedules and physically demanding work were associated with markers of ovarian reserve and response.MethodsThis analysis included women (n=473 and n=313 for ovarian reserve and ovarian response analysis, r…

Higher concentrations of certain phthalate metabolites are associated with adverse reproductive and pregnancy outcomes, as well as poor infant/child health outcomes. In non-pregnant populations, phthalate metabolite concentrations vary by r…

OBJECTIVE: To investigate the association between urinary triclosan concentrations and antral follicle count (AFC), a well-accepted marker of ovarian reserve, among women from a fertility center. DESIGN: Prospective cohort study. SETTING:…

Experimental data in rodents suggest that the effects of bisphenol A (BPA) on oocyte development may be modified by dietary methyl donors. Whether the same interaction exists in humans is unknown. We evaluated whether intake of methyl donor…

OBJECTIVE: To evaluate the relationship between pretreatment intake of whole grains and outcomes of IVF. DESIGN: Prospective cohort study. SETTING: Academic medical center. PATIENT(S): A total of 273 women who collectively underwent 438 …

BACKGROUND: Animal studies demonstrate that several phthalates are embryofetotoxic and are associated with increased pregnancy loss and malformations. Results from human studies on phthalates and pregnancy loss are inconsistent. METHODS: W…

OBJECTIVE: To explore the relationship between urinary paraben concentrations and IVF outcomes among women attending an academic fertility center. DESIGN: Prospective cohort study. SETTING: Fertility clinic in a hospital setting. PATIENT…

BACKGROUND: Evidence from both animal and human studies suggests that exposure to phthalates may be associated with adverse female reproductive outcomes. OBJECTIVE: We evaluated the associations between urinary concentrations of phthalate …

STUDY QUESTION: Are urinary phthalate metabolites associated with reduced antral follicle growth among women in an infertility setting? SUMMARY ANSWER: Higher urinary concentrations of di(2-ethylhexyl) phthalate (DEHP) metabolites were ass…
