OBJECTIVE: Vaginal lubricants appear to negatively impact sperm motility in vitro; however, it is unknown if this translates into lower fertility in women using lubricants while trying to conceive. The aim of this study was to determine if vaginal lubricant use results in lower fecundability (probability of pregnancy in a given menstrual cycle).

DESIGN: Prospective time-to-pregnancy cohort study

MATERIALS AND METHODS: Women aged 30 to 45, with no known history of infertility, who identified themselves as trying to conceive for 3 months or less were eligible. Participants completed a baseline questionnaire, including demographic information, medical and behavior history, and lubricant use (type and frequency). Women were followed without intervention until a positive pregnancy test or until censoring at 6 months of trying to conceive. Data were analyzed using cox proportional hazard modeling to determine fecundability and to calculate fecundability ratios.
CONCLUSIONS: Approximately 25% of women aged 30-45 use vaginal lubrication while trying to conceive. Lubricant use does not appear to significantly impact natural fecundability for these women.
