Lubricants are used by couples during sexual intercourse for numerous reasons, and several lubricants are promoted as “sperm-friendly,” suggesting that they do not negatively affect sperm motility.

When comparing sperm-friendliness among commercial brands, Pre-Seed was superior to Optilube, which in turn was superior to Yes Baby.
