Exposure to polyoxyethylene tallow amines (POEAs), glyphosate co-formulation surfactants, in a US pregnant population and their potential endocrine disrupting effects.

Environmental pollution (Barking, Essex : 1987) ·doi:10.1016/j.envpol.2025.126205

Emerging but inconsistent evidence suggests that glyphosate (GLY)-based herbicides (GBHs) are more toxic than the active ingredient, GLY alone. Polyoxyethylene tallow amines (POEAs) are surfactants most widely used in GBH formulations, maki…

Associations of Exposure to Air Pollution during the Male Programming Window and Mini-Puberty with Anogenital Distance and Penile Width at Birth and at 1 Year of Age in the Multicenter U.S. TIDES Cohort.

Environmental health perspectives ·doi:10.1289/ehp12627

BackgroundAmbient air pollution may be a developmental endocrine disruptor. In animal models, gestational and perinatal exposure to diesel exhaust and concentrated particulate matter alters anogenital distance (AGD), a marker of prenatal an…

Personal care products: Demographic characteristics and maternal hormones in pregnant women from Puerto Rico.

Environmental research ·doi:10.1016/j.envres.2021.112376

Personal care products (PCPs) refer to a wide variety of items commonly characterized as health or beauty products. PCPs contain a number of ingredients, often including a wide range of endocrine disrupting chemicals such as phthalates and …

Association of biomarkers of exposure to metals and metalloids with maternal hormones in pregnant women from Puerto Rico.

Environment international ·doi:10.1016/j.envint.2020.106310

BackgroundMetal(loid)s have been associated to adverse birth outcomes in experimental and epidemiological studies, but the underlying mechanism(s) are not well understood. Endocrine disruption may be a mechanism by which the metal(loid)s im…

Predictors of Steroid Hormone Concentrations in Early Pregnancy: Results from a Multi-Center Cohort.

Maternal and child health journal ·doi:10.1007/s10995-018-02705-0

Objectives To identify factors predicting maternal sex steroid hormone concentrations in early pregnancy. Methods The Infant Development and the Environment Study recruited healthy pregnant women from academic medical centers in four US cit…

First-Trimester Urinary Bisphenol A Concentration in Relation to Anogenital Distance, an Androgen-Sensitive Measure of Reproductive Development, in Infant Girls.

Environmental health perspectives ·doi:10.1289/ehp875

IntroductionEvidence from animal models suggests that prenatal exposure to bisphenol A (BPA), a ubiquitous endocrine-disrupting chemical, is associated with adverse reproductive outcomes in females. Exposure during early gestation, a critic…

Perfluoroalkyl substances and ovarian hormone concentrations in naturally cycling women.

Fertility and sterility ·doi:10.1016/j.fertnstert.2015.02.001

ObjectiveTo examine associations between environmental exposure to perfluoroalkyl substances (PFASs) and ovarian hormone concentrations in naturally cycling women.DesignE2 and P were measured in saliva samples collected daily for a single m…

Environmental exposure to di-2-ethylhexyl phthalate is associated with low interest in sexual activity in premenopausal women.

Hormones and behavior ·doi:10.1016/j.yhbeh.2014.10.003

Phthalates, a ubiquitous class of environmental chemicals, may interfere with typical reproductive hormone production both in utero and in adulthood. Although they are best known as anti-androgens, increasingly, evidence suggests that phtha…

Anogenital distance is related to ovarian follicular number in young Spanish women: a cross-sectional study.

Environmental health : a global access science source ·doi:10.1186/1476-069x-11-90

BackgroundIn animals, anogenital distance (AGD) at birth reflects androgen levels during pregnancy and predicts adult AGD. Little is known about AGD in relation to female reproductive characteristics in humans, a question this study was des…
