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. Results from a study published in the International Journal of Gynecology & Obstetrics indicate that these marketing claims may be inaccurate and misleading.

The study tested the sperm-friendliness of Pre-Seed, Yes Baby, Optilube, , and egg white to optimize the likelihood of conception in couples. With the exception of egg white, all lubricants caused significant reductions in compared with untreated controls. When comparing sperm-friendliness among commercial brands, Pre-Seed was superior to Optilube, which in turn was superior to Yes Baby.

"This study is important because it highlights that these so-called sperm-friendly lubricants may actually hinder normal conception," said lead author Johan Markram, MBChB, MMed, MPharm, of the University of Pretoria, in South Africa.
