Sperm friendly and paraben-free, our fertility lubricant is ideal for couples trying to conceive. Opt for our convenient lube subscription option to enjoy a hassle-free supply each month, along with a subscriber-exclusive discount.

    Protects sperm health

    The Lube is sperm friendly because of its special formula: its pH, osmolality, and viscosity are designed to support sperm viability. Unlike conventional everyday lubricants, The Lube is compatible with TTC, making it a great lube subscription option to have on hand whether TTC or not.

    Made without parabens

    Made without parabens

    Parabens are endocrine disruptors. Preliminary evidence from a study conducted at Harvard University linked high paraben build up in the body with reduced fertility. When TTC, stay paraben-free.
