A tampon is a (usually disposable) plug that a woman inserts into her vagina during her menstrual period to absorb the flow of blood. The Food and Drug Administration (FDA) of the United States regulates tampons as medical devices. In the United Kingdom they count as luxuries and hence have VAT.

History

There is evidence which suggests that women have been using tampons made of various materials for thousands of years. The tampon with an applicator and string was invented in 1929 and submitted for patent in 1931 by Dr. Earle Haas, an American from Denver, Colorado. Tampons based on Dr. Haas' design were first sold in the U.S. in 1936.

Design and packaging

Tampons come in various sizes, which are related to their absorbency ratings and packaging. The shape of all tampons is basically the same; cylindrical. Tampons sold in the United States are made of
cotton, rayon, or a blend of the two. Tampons are sold individually wrapped to keep them clean, although they are not sterile. They have a string for ease of removal, and may be packaged inside an applicator to aid insertion.

Tampon applicators may be made of plastic or cardboard, and are similar in design to a syringe. The tampon rests inside a hollow tube, which has a narrower tube nested inside one end of it. The open end of the applicator is placed and held in the vagina, then the woman presses the narrower tube in with her fingers. The narrow tube slides into the wider tube, pushing the tampon through and into the vagina.

Tampons are also sold without applicators; these are simply unwrapped and pushed into the vagina with the fingers.

Absorbency ratings

Tampons come in several different absorbency ratings, which are consistent across manufacturers in the U.S.:

  • Junior absorbency: 6 grams and under
  • Regular absorbency: 6 to 9 grams
  • Super absorbency: 9 to 12 grams
  • Super plus absorbency: 12 to 15 grams
  • Ultra absorbency: 15 to 18 grams

Toxic shock syndrome

Tampons have been shown to have a connection to
toxic shock syndrome (TSS), a rare but sometimes fatal disease. The U.S. FDA suggests the following guidelines for decreasing the risk of contracting TSS when using tampons:

  • Follow package directions for insertion
  • Choose the lowest absorbency for your flow
  • Change your tampon at least every 4 to 8 hours
  • Consider alternating pads with tampons
  • Know the warning signs of toxic shock syndrome
  • Don't use tampons between periods

Environmental impact

Tampons, their applicators, and wrappings are used once and then either flushed down a toilet, or disposed of in trash. If flushed down a toilet, they end up in
sewage treatment plants, and eventually, local groundwater or oceans. If disposed of in the trash, they may end up in landfills, where they can take up to six months to biodegrade.

Some tampons are made with genetically modified (GM) cotton. Chlorine bleach is also used in the manufacture of tampons. Chlorine is associated with a number of serious environmental problems, including dioxin contamination, and ozone depletion through production of chlorofluorocarbons (CFCs).

Among tampon users, each woman is likely to use about 10,000 tampons during her lifetime.

Alternatives

In industrial countries, some women's health or environmental concerns result in their preferring not to use tampons. They have several alternate ways of absorbing menstrual fluids available. Women in developing countries are unlikely to have all of these choices (including tampons) available.
  • Disposable
    • disposable menstrual pads (sanitary napkins/towels)
  • Reusable
    • washable menstrual pads
    • small natural sponges
    • menstrual cups
