Women and HIV
Vaginal sex is one of the primary ways a person can become infected with HIV. According to the U. Globally, the figures are even more dismaying. While the sexual transmission of HIV in the U.
This is especially true in Africa where most new infections are among heterosexuals. In these populations, vaginal sex is the predominant route of infection. From a purely statistical standpoint, anal sex is considered the highest risk activity with an almost fold greater risk of infection compared to vaginal sex. But this assessment is somewhat misleading, at least from an individual perspective. Consider for a moment that women are three to four times more likely to get HIV from men than the other way around.
Conversely, there are some men who are far more likely to get HIV than others. Vulnerabilities vary by individual, so assessing what the real risk of vaginal sex requires a better understanding of the factors that place some women and men at greater risk than others.
The risk of HIV from unprotected vaginal sex is higher among women for a number of reasons. From a physiological standpoint, the tissues of the vagina epithelium are far more susceptible to HIV than those of the penis.
HIV is able to pass through these tissues when the immune system recognizes the invading virus and send defensive cells called macrophages and dendritic cells to "grab and drag" them through the lining to be destroyed. By doing so, the body helps facilitate its own infection. And, because the surface area of the vaginal epithelium is far greater than that of the male urethra, the opportunity for infection is increased, often exponentially.
Other physiological vulnerabilities include:. While the daily use of an HIV drug called pre-exposure prophylaxis PrEP can dramatically decrease the risk of HIV in an uninfected partner, there is evidence that works less well in women. Research published in suggests the level of the active drug molecule in vaginal tissue isn't near as high as in rectal tissue. None of this, of course, takes into account any of the social vulnerabilities that can place women at increased risk.
These include sexual violence in relationships which not only steals a woman's chance for self-protection but can result in damage to delicate vaginal tissue. All of these contribute to higher rates of HIV in women.
The fact that men are less susceptible to HIV than women shouldn't underplay the fact that they also have vulnerabilities that can increase their personal risk of infection. We know, for example, that an uncircumcised penis can facilitate infection due to the bacteria-rich environment beneath the foreskin.
Sexually transmitted infections and genital tract infections can further increase the risk of HIV. It creates a double standard that can place a man at greater risk of HIV by associating virility with multiple partners or other high-risk behaviors.
Among them:. A high viral load during acute infection the stage immediately following exposure is associated with an increase in HIV risk. Drinking alcohol or taking drugs can lower inhibitions and affects a person's ability to make safe choices, such as using condoms or remaining adherent to HIV drug therapy. From the perspective of per-exposure risk the chance of getting HIV from a single sexual act , risk can vary based on gender, the viral load of the HIV-positive partner, and even the part of the world you live in.
These figures do not take into account any other factors that can increase risk, including the presence of an STI, injecting drug use, or a co-existing infection like hepatitis C. Assessing your personal risk for HIV should never be a numbers game.
Doing so may entirely erase the risk of transmission. And don't forget the tried-and-true condom, which is associated with a decrease in risk if used correctly and consistently. By formulating a holistic approach to prevention, you can continue to enjoy a healthy sex life while protecting yourself or a loved one from the risk of HIV.

What Is the Risk of HIV From Vaginal Sex?
During a median follow-up period of 1. No HIV transmissions occurred. The investigators concluded that the risk of HIV transmission through vaginal intercourse in these circumstances was effectively zero Rodger.

How Is HIV Transmitted?
When it comes to contracting HIV, some acts are riskier than others. Here are the HIV transmission rates by type of exposure. It takes only one instance of exposure to become infected with the human immunodeficiency virus, or HIV. Here, approximately, are the odds of getting HIV , broken down by type of exposure — and how to reduce your risk. The reason is that needles, syringes, and other equipment can contain blood, and therefore HIV, which can then be directly transmitted into the bloodstream. Under the right environmental circumstances, the virus can survive in a used needle for up to 42 days, according to the U. Department of Health and Human Services.
Vaginal Sex and HIV Risk
Q: What are the chances of a man being infected after condomless sex with a woman who has HIV? In general, the risk of a man getting HIV from an HIV-positive woman during vaginal intercourse in the United States is low--probably less than 1 of 1, exposures will result in actual infection. This risk may be higher depending on certain factors, such as whether the woman is having her period or whether the man is uncircumcised, and it also may be higher in poor countries.
Can You Get HIV From Having Sex With Someone Who Has AIDS?
Harm reduction during a pandemic. Now more than ever, we need a safe supply of drugs. What do the latest studies tell us about this risk? And how should we interpret and communicate the results?
Vaginal sex intercourse involves inserting the penis into the vagina. Some sexual activities are riskier than others for getting or transmitting HIV. Activities like oral sex, touching, and kissing carry little to no risk for getting or transmitting HIV. In addition to HIV, a person can get other sexually transmitted diseases STDs like chlamydia and gonorrhea from vaginal sex if condoms are not used correctly. Even if a condom is used, some STDs can still be transmitted through skin-to-skin contact like syphilis or herpes.
Several factors can increase the risk of HIV in women. For example, during vaginal or anal sex, a woman has a greater risk for getting HIV because, in general, receptive sex is riskier than insertive sex. HIV is spread through the blood, pre-seminal fluids, semen, vaginal fluids, rectal fluids, or breast milk of a person who has HIV. Age-related thinning and dryness of the vagina may also increase the risk of HIV in older women. A woman's risk of HIV can also increase if her partner engages in high-risk behaviors, such as injection drug use or having sex with other partners without using condoms. However, birth control and pregnancy are two issues that can affect HIV treatment in women. Birth control Some HIV medicines may reduce the effectiveness of hormonal contraceptives, such as birth control pills, patches, rings, or implants. Women taking certain HIV medicines may have to use an additional or different form of birth control.
