You can only achieve excellent contraceptive effectiveness when you use your barrier contraceptive (Milex diaphragm, FemCap, or Caya) together with a contraceptive gel. But you have a choice: you can use classic Nonoxynol-9 spermicide gel, or the natural alternitive, ContraGel. . . What's Wrong With N-9 Spermicide? Typical Nonoxynol-9 spermicides like Gynol and Gygel are chemical surfactants — they have the same chemical makeup as harsh cleaning products. To do their job, N-9 spermicides attack cells, break them down, and effectively kill them. But spermicide does not pick and choose which cells to attack. In addition to sperm, spermicide also attacks sensitive intimate skin cells. . That's why so many woman and men report burning, irritation and rashes after using N-9 products. A second concern when using spermicides is the porous vaginal mucous membranes absorbing the chemicals allowing toxins to travel into your skin and throughout your entire body. ContraGel Medical Studies ContraGel is the safe natural spermicide alternative. ContraGel contains no Nonoxynol-9, is vegan, and totally non-toxic. ContraGel was even formulated to be compatible with and not disrupt vaginal pH. The choice between ContraGel and nonoxynol-9 spermicide should be obvious —but is there a difference in effectiveness? . In an outstanding new medical study, ContraGel was proven to be just as effective as Nonoxynol-9 spermicides when paired with diaphragms. This is a massive victory for women all over the world who were waiting for confirmation that their birth control method is as effective as it is natural. Body-friendly, eco-friendly, and natural ContraGel is the clear winner in the battle of the contraceptive gels. . In addition to the groundbreaking new study, ContraGel effectivity and safety are well established. ContraGel is CE certified for use as a contraceptive gel used with a barrier contraceptive. It has a long history of customer satisfaction and excellent ratings. It was manufactured from 1972 until 2003 under the name Contracep Green and was more recently rebranded ContraGel Green. . How ContraGel Works ContraGel works in two ways: First, it reduces the PH levels in the vagina making it less hospitable to sperm. Second, it's viscous consistency traps sperm to prevent it from swimming past any openings around the barrier contraceptive. . Studies show that this combined effect functions to increase the contraceptive reliability of barrier contraceptives equally well to typical spermicides. . ContraGel is formulated from six simple ingredients: Water, Lactic Acid, Sodium Lactate, Methyl Cellulose, Sorbic Acid, and Vanillin. . ContraGel is water soluble and safe to use with silicone diaphragms and cervical caps, as well as latex or polyurethane condoms. It was determined to be highly compatible with YES brand water-based lubricants. . . ContraGel Best Price ContraGel believes in approachable pricing. Each tube of ContraGel lasts for 15 to 20 applications, and choosing a value 3-pack makes ContraGel even more affordable than many other spermicides.
