Pre-Seed is the only lubricant formulated by a woman Sperm Physiologist.
Meet Dr. E and learn more about her research.
Preservatives, such as methylparaben and propylparaben (in Pre-Seed lubricant), keep products from growing bacteria. Unfortunately, other preservatives (Vitamin C, EDTA, etc.) can cause sperm damage or death. We chose to use methylparaben and propylparaben because they have very long histories of use and safety data.
The preservatives we use prevent bacteria growth without damaging sperm. Published reports found that these preservatives have no more impact on tissues than do food estrogens in soya and other foods (A review of the endocrine activity of parabens and implications for potential risks to human health. Crit Rev Toxicol. 2005).
INGfertility scientists and expert preservative consultants have reviewed all of the available preservatives approved for human use. In developing Pre~Seed our goal, of course, was to choose a preservative that was safe for sperm. Unfortunately, many preservatives damage sperm by their mechanism of action. In developing Pre-Seed, INGfertility did the first, and to our knowledge the only, studies ever done to determine the lowest dose of methylparaben and propylparaben preservatives we could use that would meet our goal of protecting against bacterial growth while preserving optimal sperm function and not impairing egg fertilization or embryo development.
The safety issues around parabens have been reviewed by a number of expert groups. Virtually all of them have concluded that methylparaben and propylparaben, when used in the amounts present in Pre-Seed, are safe.
The FDA believes that “at the present time there is no reason for consumers to be concerned about the use of cosmetics containing parabens. However, the agency will continue to evaluate new data in this area. If FDA determines that a health hazard exists, the agency will advise the industry and the public…”
