Pre’ is the first Isotonic vaginal lubricant, making it less irritating than other lubricants and able to replenish mois¬ture without harming sperm or embryos for women trying to conceive. Pre’ is designed to mimic natural body secretions to relieve dryness — with the same osmolarity and ph-balance as fertile cervical mucus and semen. INGfertility’s lubricants are the first and currently only products in the United States that are allowed to claim that they: are safe for use by couples who are trying to conceive; don’t harm sperm or embryos; and are appropriate for use during fertility interventions, such as: - intrauterine insemination - in vitro fertilization - embryo transfer - transvaginal oocyte collection
