The development of functional hypothalamic amenorrhea (FHA) in weight-stable, nonathletic women has long been thought to be psychogenic in origin. This study was designed to gain insight into the possibility that nutritional deficits and compensatory endocrine-metabolic adaptations contribute to the development and maintenance of FHA of the psychogenic(More)
BACKGROUND Epidemiologists often use menstrual cycle patterns as indicators of endocrine function in environmental and occupational studies, yet few studies have considered whether menstrual cycle characteristics are associated with fertility or pregnancy outcome. METHODS We prospectively studied 470 women to determine whether cycle length or bleed length(More)
OBJECTIVE To examine the effect of follicular fluid (FF) and peritoneal fluid (PF) from patients undergoing assisted reproductive technology procedures on endothelial barrier function. This was determined in vitro by measuring the permeability of filter-grown bovine aortic endothelial cell monolayers to a permeability marker. DESIGN Endothelial cells(More)
We previously suggested that women with endometriosis have increased oxidative stress in the peritoneal cavity. To assess whether antioxidant supplementation would ameliorate endometriosis-associated symptoms, we performed a randomized, placebo-controlled trial of antioxidant vitamins (vitamins E and C) in women with pelvic pain and endometriosis.(More)
OBJECTIVE To assess the subjective cure rates in a group of women who had undergone delayed/secondary anal sphincteroplasty and in a subgroup of women to compare the integrity of the anal sphincteric complex as evaluated by physical examination and vaginal probe anal sonography with subjective cure rates of fecal incontinence. STUDY DESIGN The charts of(More)
PURPOSE Patterns of pubertal development reflect underlying endocrine function and exposures, and could affect future health outcomes. We used data from a longitudinal cohort to describe factors associated with breast and pubic hair stage and estimate average duration of puberty. METHODS Data from the Avon Longitudinal Study of Parents and Children were(More)
BACKGROUND The upward trend in industrial nations in the incidence of male genitourinary (GU) conditions may be attributed to increased exposure to endocrine disruptors. Polybrominated biphenyl (PBB), a brominated flame retardant, is one such suspected endocrine disruptor. OBJECTIVE We investigated the relationship between maternal serum levels of PBBs(More)
The menstrual cycle is an important indicator of underlying hormonal function. Although menstrual cycle variability (sometimes referred to as 'regularity') is associated with a variety of demographic, behavioral, occupational, and environmental factors, as well as with several chronic diseases, few studies have examined its association with fecundity. We(More)
OBJECTIVE We hypothesized that glycodelin stimulates vascular endothelial growth factor (VEGF) expression in response to oxidative stress. STUDY DESIGN EM42 (human endometrial epithelial cell line) and primary endometrial epithelial cells were subjected to oxidative stress with minimally oxidized low density lipoprotein (mLDL). Cells were also incubated(More)
OBJECTIVE This study was undertaken to prospectively assess subjective anorectal symptoms by questionnaire and to prospectively assess the integrity of the anal sphincter by physical and ultrasonographic examination in women with and without obstetric anal sphincter laceration. STUDY DESIGN Fifteen subjects who sustained obstetric anal sphincter(More)
