Osmolality is a number or range that show how dense or “full” of molecules something is. When you know a lubricant’s osmolality, you’ll know how well it will or won’t play with your body – in this case, vaginal fluids and surrounding tissue. Your body naturally works hard to keep molecules balanced –especially when something new like a lubricant is added to the mix.
Put simply, the closer a lubricant is to your intimate area’s natural osmolality levels, the more it plays well with your body! On the flipside, the farther a lubricant is from your
intimate area’s natural osmolality levels, the higher the risk for problems i.e. irritation, vaginal dryness, and even potential risk of infections.
Semen itself has an osmolality level of about 340 mOsm/kg and quality, fertility-friendly lubricants have osmolality levels that play well with natural vaginal fluids and don’t slow down sperm – Conceptria is 300-410 mOsm/kg.
