Background: Quality of life (QOL) and psychological health has been reported to be decreased among women with gynecological conditions such as uterine fibroids (UFs). Materials and Methods: Women enrolled in the Comparing Options for Manage…
PURPOSE: To evaluate the relationships among history of asthma, asthma severity, and spontaneous abortion (SAB). METHODS: Pregnancy Study Online is a preconception cohort study of North American couples. During the preconception period, fe…
Some studies indicate that Black women have higher exposure to multiple non-persistent endocrine disrupting chemicals (EDCs) than white women, but little is known about correlates of exposure to EDC mixtures. Using baseline data from a pros…
BACKGROUND: Infertility affects up to 15% of couples. In vitro fertilization (IVF) treatment has modest success rates and some factors associated with infertility and poor treatment outcomes are not modifiable. Several studies have assessed…
STUDY QUESTION: Can we derive adequate models to predict the probability of conception among couples actively trying to conceive? SUMMARY ANSWER: Leveraging data collected from female participants in a North American preconception cohort s…
BACKGROUND: Refusal to participate in studies related to sexual health can compromise the internal and external validity of findings. Research examining non-response to sexual health studies has primarily focused on predictors such as speci…
BACKGROUND: Migraine is common among females of reproductive age (estimated prevalence:17-24%) and may be associated with reproductive health through underlying central nervous system excitability, autoimmune conditions, and autonomic dysfu…
PURPOSE: To prospectively examine the association between time-to-pregnancy (TTP) and postpartum depression (PPD) and determine whether perceived stress during early pregnancy mediated this association. METHODS: In Pregnancy Study Online, …
BACKGROUND: Depression and anxiety are prevalent among women with uterine fibroids (UF). The rate of mental health diagnoses in women with UF has not been studied. METHODS: Women aged 18-50 years with diagnosed UF were identified in the Op…
OBJECTIVE: Fibroid treatments that have few side-effects and can preserve fertility are a clinical priority. We studied the association between serum vitamin D and uterine fibroid growth, incidence, and loss. DESIGN: A prospective communit…
BACKGROUND: Phthalates are endocrine-disrupting chemicals that are widely present in consumer products. In the United States, Black women are more highly exposed to phthalates than other racial/ethnic groups, yet information on predictors o…
STUDY QUESTION: Do daughters of older mothers have lower fecundability? SUMMARY ANSWER: In this cohort study of North American pregnancy planners, there was virtually no association between maternal age ≥35 years and daughters' fecundabili…
STUDY QUESTION: How accurately do women report a diagnosis of endometriosis on self-administered questionnaires? SUMMARY ANSWER: Based on the analysis of four international cohorts, women self-report endometriosis fairly accurately with a …
(Abstracted from Hum Reprod 2021;36:1268–1278) Approximately 10% of reproductive-aged women are affected by endometriosis, a condition in which endometrial-like tissue is found outside of the uterus causing severe pain and infertility. Diag…
PURPOSE: Asthma has been positively associated with irregular menses and infertility in some studies, but data are limited on the relation between asthma medication use and fecundability (i.e., average per-cycle probability of conception am…
The majority of research within reproductive and gynecologic health, or investigating ART, is observational in design. One of the most critical challenges for observational studies is confounding, while one of the most important for discove…
BACKGROUND: Injectable contraceptive use is common, with 74 million users worldwide. Use of the injectable contraceptive depot medroxyprogesterone acetate (DMPA) is associated with bone mineral density loss. We hypothesize that increased bo…
OBJECTIVE: To evaluate the association between pregravid use of a variety of contraceptive methods and subsequent fecundability. DESIGN: Prospective cohort study. SETTING: Denmark and North America, 2007-19. PARTICIPANTS: 17 954 women wh…
OBJECTIVE: To quantify the frequency of use of selected fertility awareness indicators and to assess their influence on fecundability. DESIGN: Web-based prospective cohort study. SETTING: Not applicable. PATIENT(S): Female pregnancy plan…
The association between dietary fat and fertility is not well studied. We evaluated intakes of total fat, saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, trans fatty acids (TFA), ω-3 fatty acids, and ω-6 fat…
BACKGROUND: The synthetic solvent tetrachloroethylene (PCE), commonly used in dry cleaning operations, is a human neurotoxicant and carcinogen. However, its effect on reproduction is poorly understood, as prior studies have been limited to …
STUDY QUESTION: Does inverse probability weighting (IPW) provide a more valid estimate of the cumulative incidence of live birth after multiple cycles of IVF? SUMMARY ANSWER: IPW can provide a more accurate estimate of treatment success fo…
BACKGROUND: Animal studies have shown that a high intake of galactose, a breakdown product of lactose, increases ovarian toxicity. Few epidemiologic studies, to our knowledge, have examined the association between dairy intake and fertility…
STUDY QUESTION: To what extent is preconception use of pain-relieving medication associated with female fecundability? SUMMARY ANSWER: Women who used naproxen or opioids had slightly lower fecundability than women who did not use any pain-…
Uterine leiomyomata (UL) have a substantial impact on women's health, but relatively few studies have identified opportunities for primary prevention of these neoplasms. Most established risk factors are not modifiable, including premenopau…
