Condoms have been shown by no less than 138 studies (reviewed by 38 FDA experts) to be 'no proven protection against stds' but little has been released to the public about there life threatening dangers. However the trade and medical press is filled with new reports of the massive health risk from internal exposure to vulcanized latex. Here are a few of the problems the condom user faces.

....unless you could be the type of person to be concerned about trifles like cancer, death from inhalation problems and the odd birth defect (to name a few).
Latex is a natural rubber or is not in the slightest elastic (high modulus) until it undergoes a process called vulcanization.
This requires a large number of additives. Latex even in its natural form has proteins known to cause allergic reactions (Types I, II and IV -fatal).
The additives in vulcanization include: -
Benzene - Short term exposure to benzene may cause irritation to the nose, throat and lungs. It can also affect the nervous system, causing headaches, dizziness and slurred speech. At high levels of inhalation shallow breathing and death can result. Death has occurred after exposure to 20.000ppm for five to ten minutes or 7.500ppm for 30 minutes.
Skin irritation, including redness and blistering can occur with skin contact. It is also absorbed very slowly through the skin.
Long term exposure to this substance -- even at low concentrations -- can cause a number of symptoms including appetite loss, nausea, fatigue, headaches and dizziness.
Mild anemia has been reported after exposure to 25ppm for several years and 100ppm for three months. At levels of 100ppm and 200ppm for periods of six months, or more, severe irreversible blood changes and damage to the liver and heart can occur. Benzene is a known carcinogen and it has been linked to increased risk of several forms of leukemia. In May 1977 the National Institute of Occupation Safety and Health (NIOSH) recommended that the TLV for benzene be reduced from 10ppm to 1ppm because of its carcinogenicity. NIOSH recommended that exposure to benzene be kept as low as possible and that the use of benzene as a solvent or dilutent in open operations should be prohibited. This standard of 1ppm was legally challenged by industry groups and never enforced.
Although some rubber companies said they expected to meet the 1ppm recommendation, the established TLV remains at l0ppm.
Sampling in rubber plants reveals that the level of benzene in the air is generally slightly greater than the NIOSH recommended standard of 1ppm. Researchers investigating solvent use in the rubber industry found that in order to maintain benzene vapour below 1ppm, mixtures of solvents could not contain greater than 0.1% benzene.
Toluene - This solvent, which is the major substitute for benzene, cannot be considered a completely safe alternative even though it has not been proven to be carcinogenic. The harmf ul effects of toluene include irritation of eyes, respiratory tract (nose, throat, lungs) and skin. Repeated or prolonged contact with the liquid can cause removal of all the natural oils from the skin resulting in dry, cracked skin. When splashed in the eyes, it can cause irritation and reversible damage. Acute exposure above the TLV of 100ppm can result in central nervous system depressions with symptoms including headache, dizziness, fatigue and muscular weakness as well as drowsiness and incoordination.
Thiazoles - Cause dermatitis reactions. 2-mercaptobenzothiozole is said to be especially irritating to the skin, eyes and respiratory tract.
Dithiocarbamates - Have been shown to be irritating to the skin, eyes and respiratory organs. Possible carcinogens.
•Nitrosamines (N-nitrosodiphenylamine)
Many nitrosamines are potent carcinogens but until recently this nitrosamine used as a retarder was not considered harmful. Recent experiments with rats indicted N-nitrosodiphenylam ine as a cause of cancer in the test animals. This substance also combines with other rubber chemicals to form other nitrosamines especially N-nitrosomorpholne which is linked with liver and respiratory cancer and kidney tumours.
In addittion almost all condoms have some type of lubricant such as carcinogenic talc or silicone (almost identical to that used in breast implants). Some even use the highly lethal N9 as a lubricant and spermicide.
If that was not enough in order to cause the vulcanized latex to gel on the former a coagulant is required. These salts are all highly toxic and not water soluable so the crystals remain embeded in the inner surface of the condom.
Condoms, cause for concern? You decide. It's your life after all.
LIDS - Latex allergies and the dangers of condoms

Are condoms a greater health risk than the std's they don't really protect against?
It is politically correct to advocate condoms but every day the evidence increases that they do little to protect and may pose a very serious health risk. It is hard for the CDC and FDA to examine these risks as they have been so vocal in promoting condoms but could their silence lead to dire consequences. I for one having done exaustive research strongly feel so.
"...... new concerns are arising regarding allergic or other toxic reactions to various components of latex condoms such as vulcanization accelerators, latex proteins, spermicides and finishing powders."
"* Studies are needed to evaluate the best lubricants to use in the manufacture of condoms. Evidence suggests that the right quantity, type and placement of lubricant is important for condom functionality, acceptability and safety.
In addition, the added value and risk presented by spermicidal lubricants and by dry finishing powders (e.g. talc or cornstarch) should be critically examined."
"Since the late 1980s the reported incidence
of allergy to natural rubber latex has increased dramatically, as much as 12 -fold."
"Latex allergy is incurable, although the symptoms, such as itching, soreness, painful blistering, runny noses, swollen eyes, asthma symptoms and anaphylaxis can be ameliorated.
Everyone who has contact wi th natural rubber latex is potentially at risk from sensitisation.
Both patients and health care workers can be at risk from allergic reactions to natural rubber latex. Over the past decade, allergic reactions to natural
rubber latex have become a major public health concern."
" Once a person has developed latex allergy, however mild, they are “sensitised” to latex and are at risk from severe allergic reactions."
"Delayed cell-mediated reactions are the most common form of hypersensitivity reaction to natural rubber latex. These reactions are to individual chemical residues from the production process such as accelerants used in the vulcanisation process which is required to strengthen the product.
The residual chemicals may bloo on the surface of the products and can be absorbed through the skin upon contact."
"Potent Carcinogen found in Most Condoms
Recent study has discovered the presence of a very potent carcinogen in most condoms. Small amounts of this chemical are released whenever condoms are used.
Nobody knows whether this is serious yet however it is not likely to be healthy to expose the reproductive organs to cancer-causing substances on a regular basis.
This is a potentially serious issue for much of the world's population that cannot afford or access other forms of birth control. I hope further studies will follow on this soon. Could this be related to the rise in cancer in women, and men as well? "
"Talc...(on condoms)...may result in fallopian tube fibrosis with resultant infertility. Question raised by Doctors Kasper and Chandler in Journal of the American Medical Association. (JAMA) 3/15/95
-from Nutrition Health Review, Summer 1995 n73p8(1)"
"A possible tie between talcum powder and ovarian cancer, long suspected because of talc's chemical similarity to asbestos, was strongly supported last week when a study found a higher risk of the cancer among women who used feminine deodorant sprays. The study, published in the American Journal of Epidemiology, found that women who used talcum powder in the genital area had an increased ovarian cancer risk of 60% and women who used feminine deodorant sprays had a 90% increased risk."
-from The University of California, Berkeley Wellness Letter, April 1993 v9n7p1
"Benzene. In addition to the effect on fertility, some researchers believe overexposure to chemicals may also contribute to testicular cancers. In fact, a 2000 study concluded that there was a link between sperm abnormalities and testicular cancer.
Among the study participants, men in couples with fertility problems were more likely to develop testicular cancer. In addition, low semen concentration, poor sperm motility, and abnormal sperm morphology were all associated with increased risk for testicular cancer."
"a recent Lancet study (2002;360:971-977) found frequent use may in fact increase the risk of HIV transmission.
The head of the Australian Federation of AIDS Organizations, Don Baxter, said up to 10 percent of condoms sold in Australia include nonoxynol-9 as a lubricant. "Not a high percentage of condoms use nonoxynol-9, it's usually a particular brand, but they are fairly widely available," he said. Baxter advised all gay men to avoid using condoms with nonoxynol-9 and said AFAO would call for the product to be withdrawn from pharmacy shelves. "
"The allergens that cause reactions in individuals with spina bifida are particle bound proteins that are less able to be dissolved in water than some of the other latex proteins"
* Talc - This is found in baby powders, face powders, body powders as well as some contraceptives such as condoms. Talc is a known carcinogen and is a major cause of ovarian cancer when used in the genital area. It can be harmful if inhaled as it can lodge in the lungs, causing respiratory disorders."
Condoms contain compounds known to cause cancer and serious birth defects in substantial quantities
