Nonoxynol-9 is a chemical used in some personal care products for contraception, but concerns have been raised about its safety and efficacy. It can also act as a microbicide but may increase the risk of infections. Alternative products like menphegol are recommended. Condoms and abstinence remain the most reliable ways to prevent sexually transmitted infections.
Nonoxynol-9, also known as N-9, is a chemical surfactant that has numerous uses. In the sense of health and wellness, Nonoxynol-9 is used in some personal care products designed to prevent conception, such as spermicidal jellies and creams, and condoms. Although the use of Nonoxynol-9 was once widespread and recommended, some concerns have been raised about the safety and efficacy of the product, leading some people to look for alternatives.
This product works as a spermicide by effectively paralyzing sperm cells, making it impossible for them to reach an egg and fertilize it. For people with religious beliefs surrounding the use of contraception, the use of Nonoxynol-9 is a topic of debate. Some people believe that any form of birth control is a violation of their religious beliefs, while others believe that the use of spermicides that prevent fertilization is acceptable, as a fertilized egg is never involved. Ultimately, decisions about contraception rest with individuals, who may wish to consult with their religious and medical officials.
When the researchers performed in vitro tests on Nonoxynol-9, they found that it appeared to be effective in killing some microbes. This has led researchers to suggest that in addition to acting as a spermicide, Nonoxynol-9 may also be an effective microbicide, offering protection against sexually transmitted infections in addition to contraception.
As a result of these findings, Nonoxynol-9 has become the ingredient of choice in many spermicide products. The chemical also acts as a lubricant, an added bonus in the eyes of some users. However, further research has revealed that Nonoxynol-9 actually makes people more prone to infections because it can irritate the mucous membranes, making it easier for bacteria and viruses to enter the body. In 2007, the United States Food and Drug Administration issued an advisory on Nonoxynol-9, informing consumers that while the product is an effective spermicide, it does not protect against STIs and may in fact increase the risk of transmission.
Some doctors have recommended that people who want to use spermicide look for alternative products, such as menphegol. These products provide the desired spermicidal action without irritating the mucous membranes, so they will not increase the risk of sexually transmitted infections. Currently, there are two reliable ways to eliminate or reduce, respectively, the risk of sexually transmitted infections: abstinence and the use of condoms or dental dams.
