What is the relationship between body size, physical activity and semen parameters among male partners of couples attempting to become pregnant? Overweight obesity are associated with a higher prevalence low ejaculate volume, sperm concentration total count. Higher BMI impaired parameters, while increasing waist circumference (WC) also in infertile men. Data from Longitudinal Investigation Fertility Environment (LIFE) Study were utilized. The LIFE study population-based prospective cohort...

Benzophenone (BP)-type UV filters are widely used in a variety of personal care products for the protection skin and hair from irradiation. Despite estrogenic potencies BP derivatives, few studies have examined occurrence these compounds human matrices. Furthermore, associations among exposure to estrogen-dependent diseases (such as endometriosis) not been previously. In this study, we determined concentrations five 2-hydroxy-4-methoxybenzophenone (2OH-4MeO-BP), 2,4-dihydroxybenzophenone...

Thyroid diseases are inconsistently reported to increase risk for pregnancy complications. The objective of this study was complications associated with common and uncommon thyroid diseases. We analyzed singleton pregnancies (N = 223 512) from a retrospective US cohort, the Consortium on Safe Labor (2002–2008). outcomes were derived electronic medical records. Multivariable logistic regression generalized estimating equations estimated adjusted odds ratios (ORs) 99% confidence intervals (99%...

We address the important practical problem of how to select random effects component in a linear mixed model. A hierarchical Bayesian model is used identify any effect with zero variance. The proposed approach reparameterizes so that functions covariance parameters distribution are incorporated as regression coefficients on standard normal latent variables. allow effectively drop out by choosing mixture priors point mass at for variances. Due reparameterization, enjoys conditionally...

Evidence suggesting that persistent environmental pollutants may be reproductive toxicants underscores the need for prospective studies of couples whom exposures are measured.We examined relationship between selected and couple fecundity as measured by time to pregnancy.A cohort 501 who discontinued contraception become pregnant was prospectively followed 12 months trying conceive or until a human chorionic gonadotrophin (hCG) test confirmed pregnancy. Couples completed daily journals on...

Are urinary phthalate concentrations associated with altered semen quality parameters among males recruited from the general population? Urinary levels of metabolites diesters are lower total sperm counts, larger head sizes, and higher percentages morphologically abnormal sperm. High dose experiments in rats implicate phthalates as anti-androgens. Studies involving infertile men seeking care suggest that influence measures raising concern about implications for population. This prospective...

OBJECTIVE: To investigate whether prepregnancy obesity is associated with adverse pregnancy outcomes among women without chronic disease. METHODS: Singleton deliveries (N=112,309) mothers diseases in the Consortium on Safe Labor, a retrospective U.S. cohort, were analyzed using Poisson regression robust variance estimation. Relative risks and 95% confidence intervals (CIs) estimated perinatal relation to status adjusted for age, race–ethnicity, parity, insurance, smoking alcohol use during...
