OBJECTIVE: To evaluate the relationship between epigenetic patterns in sperm and fecundity. DESIGN: Prospective study. SETTING: Academic andrology and in vitro fertilization laboratory. PATIENT(S): Twenty-seven semen samples from couples…

PURPOSE: The aim of this study was to evaluate the association between menstrual cycle characteristics in early life and adulthood and fecundability. METHODS: Pregnancy Study Online (PRESTO) is an Internet-based preconception cohort study …

STUDY QUESTION: Is sexual and/or physical abuse history associated with incident endometriosis diagnosis or other gynecologic disorders among premenopausal women undergoing diagnostic and/or therapeutic laparoscopy or laparotomy regardless …

BACKGROUND: To examine transient environmental exposures and their relationship with human fecundity, exposure assessment should occur optimally at the time of conception in both members of the couple. We performed an observational, prospec…

BACKGROUND: Many women throughout the world have history of subfertility (resolved or unresolved), but much remains unknown about services and treatments chosen. METHODS: We developed a mixed-mode fertility experiences questionnaire (FEQ) …

STUDY QUESTION: Are prospectively assessed dietary factors, including overall diet quality, macronutrients and micronutrients, associated with luteal phase deficiency (LPD) in healthy reproductive aged women with regular menstrual cycles? …

OBJECTIVE: To determine agreement on endometriosis diagnosis between real-time laparoscopy and subsequent expert review of digital images, operative reports, magnetic resonance imaging (MRI), and histopathology, viewed sequentially. DESIGN…

OBJECTIVE: The objective of the study was to evaluate whether anti-Müllerian hormone (AMH) is associated with fecundability among women with proven fecundity and a history of pregnancy loss. DESIGN: This was a prospective cohort study with…

STUDY QUESTION: What are the pain characteristics among women, with no prior endometriosis diagnosis, undergoing laparoscopy or laparotomy regardless of clinical indication? SUMMARY ANSWER: Women with surgically visualized endometriosis re…

CONTEXT: Although adequate luteal hormone production is essential for establishing pregnancy, luteal phase deficiency (LPD) is poorly characterized among eumenorrheic women. OBJECTIVE: We assessed the prevalence and overlap of two establis…

OBJECTIVE: To explore the relation between bisphenol A and 14 phthalate metabolites and endometriosis. DESIGN: Matched cohort design. SETTING: Fourteen clinical centers. PATIENT(S): The operative cohort comprised 495 women undergoing lap…

OBJECTIVE: To assess the use of cervical mucus monitoring (CMM) in women trying to conceive and determine whether monitoring is associated with increased cycle-specific probability of conception (fecundability). DESIGN: Time-to-pregnancy c…

OBJECTIVE: We sought to identify risk factors for endometriosis and their consistency across study populations in the Endometriosis: Natural History, Diagnosis, and Outcomes (ENDO) Study. STUDY DESIGN: In this prospective matched, exposure…

There has been limited study of trace elements and endometriosis. Using a matched cohort design, 473 women aged 18-44 years were recruited into an operative cohort, along with 131 similarly aged women recruited into a population cohort. End…

BACKGROUND: Caffeinated beverages are widely consumed among women of reproductive age, but their association with reproductive hormones, and whether race modifies any such associations, is not well understood. OBJECTIVE: We assessed the re…

BACKGROUND: Obesity is a growing public health problem among reproductive-aged women, with consequences for chronic disease risk and reproductive and obstetric morbidities. Evidence also suggests that body shape (i.e., regional fat distribu…

OBJECTIVE: To estimate the interrater and intrarater reliability of endometriosis diagnosis and severity of disease among gynecologic surgeons viewing operative digital images. METHODS: The study population comprised a random sample (n=148…

BACKGROUND: Environmental chemicals may be associated with endometriosis. No published research has focused on the possible role of perfluorochemicals (PFCs) despite their widespread presence in human tissues. METHODS: We formulated two sa…

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…

OBJECTIVE: To estimate the incidence of endometriosis in an operative cohort of women seeking clinical care and in a matched population cohort to delineate more fully the scope and magnitude of endometriosis in the context of and beyond cli…

Background and Aims: Persistent organic pollutants (POPs) have been associated with endometriosis, though with equivocal results possibly reflecting choice of biospecimen. We sought to assess this ...
