INGfertility~BioOrigyn makes Pre-Seed fertility-friendly lubricant and Jato isotonic personal lubricant. Other lubricants have a high salt (ion) level which can cause irritation to the sensitive cells of intimacy and are toxic to sperm. Pre-Seed is the first lubricant allowed to say it is "safe for use when trying to conceive" based on published studies and regulatory review. Other lubricants harm sperm and should be avoided when pregnancy is desired.Our new every day isotonic lubricant "Jato", is available now! Jato has been shown in independent studies to be the safest, least-irritating water-soluble lubricant tested. Jato offers natural feeling, isotonic moisture for everyone. Many women who are sensitive to other products report being able to use our isotonic lubricants, even when other lubricants cause burning and irritation.
