Although the FDA eventually determined that the polyurethane condom was safe for consumer use in , 96 six epidemiologic studies have since addressed this question. Insertive oral-penile sex is an efficient route for the transmission of herpes simplex virus HSV. Decisions About Specific Sexual Practices Evidence shows that some sexual practices are associated with a greater risk of HIV transmission than others. Early epidemiologic studies on heterosexual transmission in Western countries established that male-to-female transmission in the vagina was significantly more likely than female-to-male transmission from the vagina, 39,40,43,61,62 with estimates in three studies ranging from 1. Infectious HIV exists in saliva, tears, 14 and urine 15 ; however, it has only been recovered from these fluids at extremely low titers.

The risk of HIV infection among women who have sex with women appears to be largely attributable to other risk factors sex with men, injection drug use. In general, it was asserted that polyurethane condoms were more prone to breakage and slippage, and this delayed the approval by the U. Decisions About Partner Selection Sexual contact with many persons increases the probability of coming in contact with an HIV-infected partner. Univariate analysis showed an increased risk of HIV infection associated with oral-anal sex. In addition, laboratory evidence suggests that improper use of latex condoms eg, applying an oil-based lubricant can make condoms more susceptible to breakage. There is not yet a clear understanding of the probability of superinfection at the individual or population level, nor do we fully understand its impact on the long-term health of HIV-infected individuals. Transmission of HIV to the receptive partner probably occurs as a result of the deposition of HIV-infected semen on traumatized rectal mucosa. Hence, saliva, tears, and urine are highly unlikely sources of HIV transmission. It is believed that condom failure rates may be higher for anal sex. Permeability to Viruses Several laboratory experiments were conducted to test the ability of latex condoms to provide an effective physical barrier against HIV. Women in some developing countries may be more infectious due to higher prevalence of sexually transmitted infections STIs and untreated HIV disease, although the authors state that evidence for the relative importance of these factors is unclear. Whether being the inserting partner in unprotected penile-anal sex is an independent risk factor for HIV infection is not well understood. With this privilege comes the responsibility to be respectful and nonjudgmental. It is important to keep in mind that safety and efficacy have not been demonstrated in anal use, and that female condoms are neither recommended nor approved for this purpose. Based on the scientific evidence discussed in this chapter, Table 2 classifies sexual practices by their level of risk for HIV transmission. As efforts to develop even more effective treatments and preventive vaccines continue, it is critical to continue aggressive prevention efforts as a vital component of the battle against HIV. In a large multicenter cohort study of MSM, the investigators devised a composite variable called "rectal trauma," composed of enema usage, receptive fisting, report of blood around the rectum, and evidence of scarring, fissure, or fistula on examination. These latex squares can be purchased at condom specialty stores and some drugstores available in different flavors , or similar barriers can be made by cutting a latex condom or a latex glove. Estimating precise per-act risk is difficult because so few people practice oral sex to the exclusion of other, higher-risk sexual activities. Proper use of barrier methods can reduce the risk of transmission associated with many of these practices. Studies of male-to-female and female-to-male transmission provide strong epidemiologic evidence that heterosexual transmission of HIV does occur via penile-vaginal intercourse. Condoms are therefore recommended as an important HIV prevention measure. Thus, prevention remains the main line of defense for these individuals. In addition, although theoretical models have suggested that ART may combat the HIV epidemic on a population level, models that assumed steady or increased levels of safer-sex practices were more likely to predict reduction in new HIV infections than models that assumed decreased levels of safer sex. Decisions About Specific Sexual Practices Evidence shows that some sexual practices are associated with a greater risk of HIV transmission than others. One study has shown that the structural integrity of female condoms is not significantly damaged in up to five uses if disinfected in diluted household bleach and water 1 part bleach to 4 parts water for not more than 30 minutes, washed in diluted dishwashing liquid or bar soap and water, and air dried or dried carefully by hand. Researchers have explored whether polyurethane female condoms can be reused.
