All studies on condom efficacy in the United States were conducted with heterosexual couples performing vaginal sex. Differences in male and female brain size are relative to body size. Typically, male brains are more asymmetric than female brains. No leakage of HIV across latex condoms was demonstrable. However, all studies that have controlled for competing risk behaviors 35,36,38,40,69,70 have concluded that oral-vaginal sex is extremely low risk.

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. More recently, studies have suggested that exposure to infected pre-ejaculate through anal intercourse may also carry a high risk of transmission. Infectious HIV exists in saliva, tears, 14 and urine 15 ; however, it has only been recovered from these fluids at extremely low titers. This study controls for external societal influence by using monkeys as the subject, and projects results to humans, the closest animal relative. The model shows that individuals can reduce their risk by choosing a partner who has tested HIV negative, choosing a safer-sex act, using a condom, or some combination of these factors. Studies of the in vivo efficacy of N-9 have shown that N-9 reduces the risk of HIV transmission in some cases but not in others. Table 1 summarizes practical instructions for the use of barrier methods. However, should individuals accidentally or intentionally come in contact with HIV-infected breast milk during sex, care should be taken to avoid mucosal contact. Proper use of barrier methods can reduce the risk of transmission associated with many of these practices. Thus, the percentage of grey matter appears to be more related to brain size than it is to gender. In addition, no report has documented cases of HIV transmission by these fluids. Given the importance of sexual transmission in the HIV epidemic, many HIV prevention strategies have focused on identifying and promoting safer-sex practices. Most notably, males have a larger amount of white matter in the frontal and temporal perisylvian region, and in the temporal stem and optic radiation, of the left hemisphere, whereas females have a larger amount of gray matter in the superior temporal gyrus, planum temporale, Heschl gyrus, cingulate gyrus, inferior frontal, and central sulci margins, of the left hemisphere. This difference and other sensory differences like it could be because of the sex hormones that impact the fetal brain during development. This may be because the female auditory cortex is more dense than that of the male. Testosterone is the major active hormone in male development while estrogen is the dominant female hormone. There are also differences in the structure of and in specific areas of the brain. This association was no longer statistically significant once the authors controlled for other high-risk behaviors. Although female condoms are not approved for anal use, some MSM have nonetheless begun to use them for anal sex. With respect to language, males predominantly use their left hemisphere but females use both their right and left hemispheres. This innate mechanism is evolutionary in the sense that the hormones for females are concurrently passed down to other females, and the same with males. Most early studies did not demonstrate a statistically significant association between this practice and HIV infection among MSM. A review in Nature Reviews Neuroscience observed that "because it is easier to manipulate hormone levels than the expression of sex chromosome genes, the effects of hormones have been studied much more extensively, and are much better understood, than the direct actions in the brain of sex chromosome genes. Reasons for Condom Failure As the results of HIV transmission studies indicate, being made of material impermeable to HIV in a laboratory ie, latex or polyurethane is not sufficient to ensure that condoms will provide complete protection during real-life usage. On average, female brains have a larger ratio of grey matter to white matter than males particularly in dorsolateral prefrontal cortex and superior temporal gyrus , even when sex-differences in total intracranial volume are taken into consideration.

  1. Numerous studies suggest that, on average, female brains have more commissural tracts involved in inter-hemispheric connectivity than males. It is therefore important in high-prevalence settings to continue to encourage risk reduction behaviors that include both safer sex practices and HIV testing.

  2. Epidemiologic Studies and Case Reports Epidemiologic evidence in support of male-to-male, male-to-female, and female-to-male 31,33,36,39,40, sexual transmission of HIV infection is abundant.

  3. The gradual growth in sex difference throughout a person's life is a product of various hormones.

  4. When both sexual partners are HIV positive, it is still reasonable to consider safer-sex practices to reduce the likelihood of infection from other sexually transmitted diseases, such as herpes, gonorrhea, chlamydia, syphilis, and hepatitis B and C viruses. Comparing a man and a woman of the same body size, an average difference of grams in brain-mass is present, the man having the bigger and heavier brain.

  5. In addition, condom breakage or failure may occur. Decisions About Specific Sexual Practices Evidence shows that some sexual practices are associated with a greater risk of HIV transmission than others.
