Previous studies have reported that over-the-counter vaginal lubricants (Astroglide, KY Jelly, and Replens) can negatively affect sperm motility in a laboratory setting. Fertility specialists have long advised patients against using these products while trying to conceive. It is estimated that 25% of women have used these products within the past month. A new study published in Obstetrics & Gynecology by researchers affiliated with the University of North Carolina and the University of Virginia revisits this issue. They evaluated the impact of lubricants on fertility in human couples.
Anne Z. Steiner, MD and her investigators studied 296 women between 30 and 44 years old with no history of fertility problems. All were trying to conceive less than 3 months. Based on a daily diary that was kept, 57% of women never used a lubricant, 29% occasionally used a lubricant, and 14% used a lubricant frequently. After the data was analyzed, the women who used lubricants during the fertile window had a comparable chance to conceive as those who did not use lubricants. In fact, women who frequently used vaginal lubricants — about 14 percent of women in the study — were just as likely to get pregnant as those who never used lubricants.
The authors concluded that using lubricants during procreative intercourse does not appear to have a negative effect on natural fertility. Steiner emphasizes that the study does have limitations and further research is needed to confirm the findings. If a couple is having issues with vaginal dryness and needs to use a lubricant, they can be somewhat reassured by these findings,” Steiner said
