McInerney KA, et al. - Researchers assessed the extent to which lubricant use during intercourse correlates with time to pregnancy (TTP) via two continuing prospective cohort studies of pregnancy planners in Denmark (2011–2017) and North America (2013–2017). They categorized self-reported lubricant use as water-based/not pH balanced, water-based/pH balanced “fertility friendly,” silicone-based, oil-based, or a combination of these. At baseline, lubricant use was reported in 17.5% of participants, most commonly water-based/not pH balanced. Outcomes revealed no correlation of lubricant use with reduced fecundability in the preconception cohorts of pregnancy planners studied.
