In this study, personal lubricants were evaluated for couples trying to conceive (TTC). While there are an increasing number of commercial products available to help alleviate vaginal dryness, there is concern regarding the possible negative effects of these lubricants on fertility. Studies have demonstrated that surgical gels, saliva, olive oil, and leading personal lubricants, such as Astroglide and K-Y jelly, are detrimental to sperm motility and chromatin integrity. This research confirmed that these coital lubricants caused a remarkable decrease in sperm motility. On the contrary, Pre-Seed exhibited no significant decline in total sperm motility.
