Sperm‐friendly lubricant : Fact or fiction
Abstract Objective To assess the effects of “sperm‐friendly” coital lubricants on sperm motility. Methods This study compared the effects of five lubricants (Optilube®, Pre‐Seed®, Yes Baby®, olive oil, and egg white) on sperm motility in 60 normozoospermic semen samples obtained from men attending a private fertility clinic. Samples were exposed to each of the lubricants, with untreated samples serving as controls, and were examined microscopically at four defined time‐points from 2 to 72 h after liquefaction. Sperm motility was graded according to World Health Organization criteria. Results With the exception of egg white, all lubricants caused significant ( P < 0.001) reductions in sperm forward progression compared with untreated controls until 24 h after liquefaction. Furthermore, between‐group comparisons of the commercially available lubricants revealed statistically significant differences in forward progression motility: Pre‐Seed® was superior to Optilube® ( P < 0.001), which in turn was superior to Yes Baby® ( P < 0.001) at 2–4 h after exposure. Significance ( P < 0.001) between Pre‐Seed® and Yes Baby® was maintained until 24 h. Conclusion Although spermatozoa exposed to Pre‐Seed® demonstrated greater motility than spermatozoa exposed to Yes Baby®, claims that these lubricants are sperm‐friendly were refuted. Conversely, egg white was shown to be a sperm‐friendly lubricant for couples who are trying to conceive..
