Studies of human trisomies indicate a remarkable relationship between abnormal meiotic recombination and subsequent nondisjunction at maternal meiosis I or II. Specifically, failure to recombine or recombination events located either too near to or too far from the centromere have been linked to the origin of human trisomies. It should be possible to(More)
PURPOSE We recently reported evidence suggesting associations between urine cadmium concentrations, reflecting long-term exposure, measured in 25 female patients (relative risk = 1.41, P = 0.412) and 15 of their male partners (relative risk = 0.19, P = 0.097) and oocyte fertilization in vitro. Blood cadmium concentrations reflect more recent exposure. (More)
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 POPs and the odds of an endometriosis diagnosis and the consistency of findings by biological medium and study cohort.(More)
Insulin-like growth factor (IGF)-binding proteins (IGFBPs) antagonize IGF and gonadotropin actions on granulosa cells. Human atretic follicles express IGFBP-2 in granulosa cells more strongly and contain higher levels of IGFBP-2 and IGFBP-4 than healthy follicles. We studied the effects of interferon-gamma (IFN gamma) and activin A, which decrease(More)
PURPOSE To investigate whether follicular fluid lipid-soluble micronutrients are associated with embryo morphology parameters during IVF. METHODS Follicle fluid and oocytes were obtained prospectively from 81 women. Embryo morphology parameters were used as surrogate markers of oocyte health. HDL lipids and lipid-soluble micronutrients were analyzed by(More)
The importance of high-density lipoprotein (HDL) particle components to reproduction is increasingly recognized, including the constituent paraoxonase 1 (PON1). However, the reliability characteristics of PON1 enzymes in ovarian follicular fluid (FF) as biomarkers for clinical and epidemiologic studies have not been described. Therefore, we characterized(More)
