ObjectiveTo determine the impact of sexual intercourse around the time of implantation on the probability of achieving a pregnancy.DesignTime-to-pregnancy cohort using day-specific probability of pregnancy modeling to account for intercours…
ObjectiveTo 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).DesignTime-to-pregnancy cohort …
High serum follicle-stimulating hormone (FSH) levels have been associated with diminished ovarian reserve; however, the association between high urinary FSH and reduced natural fertility has yet to be established. We sought to characterize …
ObjectiveOver-the-counter vaginal lubricants have been shown to negatively affect in vitro sperm motility. The objective of this study was to estimate the effect of vaginal lubricant use during procreative intercourse on natural fertility.M…
