We do our homework. See the research behind The Lube.
The Lube is formulated and FDA cleared to be fertility friendly.
The Lube is a fertility-friendly, sperm-friendly lubricant because of its special formula. Its pH, osmolality, and viscosity are designed to support sperm health. Even if other conventional lubricants do not contain spermicide, they can harm healthy sperm by not being properly formulated for these factors. If you’re TTC, it's important to use a lubricant that is compatible with your fertility journey, rather than detrimental to it.
Fertility lubricants like ours are a special class of lubricants that are cleared by the FDA for use when trying to conceive. They go through additional testing (biocompatibility) to demonstrate that they do not harm sperm cells, eggs, or embryos.
Why you may consider a fertility lubricant when TTC.
When trying to conceive, it's important to make sure your everyday lubricant doesn't interfere with fertilization. Our fertility lubricant preserves the fun and intimacy of TTC without impeding your journey. Be sure to use a TTC lubricant that doesn't affect fertility.
Unlike other lubricants, The Lube is made without parabens.
Parabens are endocrine disrupting chemicals (EDCs)—chemicals that can interfere with the endocrine system. When inside the body, parabens can mimic estrogen. Using products with parabens during pregnancy can be a potential source of paraben exposure to the pregnant person and the fetus. Because of this, the European Union (and now California!) have banned parabens in cosmetic and beauty products. This is for good reason; preliminary evidence from a study conducted at Harvard University linked high paraben build up in the body with reduced fertility. Research is still emerging, but we've opted to make our products without these potentially harmful ingredients. When TTC, stay free of parabens.
The Lube is water-based.
Our water-based lube mimics the body’s natural lubrication with a clean, frictionless consistency.
