Purpose of review: Vaginal lubricants are commonly utilized to facilitate more comfortable and enjoyable intercourse. The impact of these lubricants on fertility is unclear. The aim of this review is to summarize the current in-vitro and clinical data pertaining to lubricants’ effect on natural conception.
Recent findings: In-vitro studies suggest lubricants can be toxic to sperm in the artificial laboratory environment. Lubricants formulated to be nontoxic to sperm have no effect on sperm motility or viability in vitro compared to controls. However, a recent longitudinal cohort study suggests lubricant use and choice has no effect of fecundity.
Summary: As a result of the conflicting in-vitro and clinical data, the effect of vaginal lubricants on fertility is still unresolved. A randomized controlled trial is needed to determine the effects of vaginal lubricants on fertility.
