STD Awareness: The HIV Epidemic at Home

Posted on by

In the United States, we understand HIV — the virus that causes AIDS — using a common narrative, one that gives us the impression that its deadliest chapters belong in decades past or distant places. It goes like this:

The disease emerged in the 1980s, cutting down young gay men in their primes and blindsiding scientists as they scrambled to unravel the virus’ mysteries. While AIDS initially whipped up mass hysteria among the general public, LGBTQ folks demanded equality, pushing to find treatments and a cure. AIDS activism and scientific research eventually led to the development of antiretroviral drugs, which tamed the plague by turning a death sentence into a chronic disease. Now, with the right medication, people with HIV can live long, healthy lives. The hysteria has died down, as most people realize viral transmission is preventable, and the infection is manageable.

One thing hasn’t changed, however: Just as it was in the 1980s, AIDS is still thought of as a disease of the “other.” Back then, it was a disease of gay men, a population cruelly marginalized by the general public. Today, it’s thought of as a disease of sub-Saharan Africa, where HIV prevalence is highest.

That narrative, however, doesn’t tell the whole story. Right here in our own backyards, the HIV epidemic continues to spread in the face of chilling indifference from those not affected. African-American MSM — men who have sex with men, who may or may not self-identify as gay or bisexual — have an HIV prevalence that exceeds that of any country in the world. In Swaziland, for example, 27 percent of adults are living with HIV/AIDS, but if current transmission rates hold steady, half of African-American MSM are projected to be diagnosed with HIV in their lifetime. Instead of taking this projection as a wake-up call to invest in lifesaving health policies, however, state and federal responses are poised to let it become a self-fulfilling prophecy.

Contrary to racist and homophobic stereotypes, data show that black MSM aren’t more likely to engage in risky sexual behavior, use drugs and alcohol, or withhold their HIV status from partners. So why are they burdened with higher HIV rates? The answer lies beyond mere behavior, embedded in policies and practices that disproportionately harm people based on race, sexuality, and geography.

Do Birth Control Pills Cause Breast Cancer? The Latest Study

Posted on by

Last month, you might have seen headlines warning you that hormonal birth control increases risk for breast cancer. This news came from a study that examined the medical records of nearly 1.8 million Danish women — and the huge sample size lent heft to the findings, several of which stood in stark contradiction to commonly held beliefs about modern hormonal contraception.

Some types of hormonal contraception could increase breast cancer risk, while others may not. But the Pill also reduces risk for endometrial and ovarian cancers.

Birth control comes in two “flavors” — hormonal and nonhormonal. Hormonal contraception is among the most effective, and includes birth control pills, hormonal IUDs, the shot, the vaginal ring, the implant, and the patch. Nonhormonal contraception ranges from very effective, including surgical sterilization and the copper IUD, to the not-quite-as-effective, including condoms, diaphragms, and withdrawal. (With the exception of condoms, birth control does not provide protection against STDs.)

Hormonal contraception is one of the greatest achievements in the history of medicine, and offers those wishing to control their fertility an array of effective options. However, as with all effective medications, there is potential for side effects. And, because many forms of hormonal birth control contain types of estrogen, and exposure to estrogen is a risk factor for breast cancer, many people wonder if hormonal birth control might increase users’ chances of developing breast cancer later in life.

Most birth control pills contain a combination of two hormones: estrogen and progestin (synthetic progesterone). Other hormonal methods, such as the ring and the patch, also use combinations of these two hormones.

There are also pills that don’t contain estrogen, called POPs, or progestin-only pills — aka the “minipill.” Additionally, hormonal IUDs, the implant, and the shot are progestin-only methods.

What Previous Studies Have Shown

The connection between hormonal contraception and breast cancer is murky, because the association is difficult to study properly. There are so many different types of hormonal contraceptives, each with different dosages, different chemical formulations, and different ways of entering the body. We can’t tease these differences apart on the one hand, but make blanket statements about hormonal contraception as a whole on the other hand. But we can look at the available evidence and see where it points. Continue reading →

Ovarian Cancer, Endometrial Cancer, and the Pill

Posted on by

The most popular method of birth control in the United States is the Pill, followed by tubal ligation (permanent sterilization, or getting your tubes tied) and condoms. The Pill is a hormonal method of contraception, while sterilization and condoms are nonhormonal. The distinction between hormonal and nonhormonal methods of birth control are simply that the former contain synthetic versions of human hormones, while the latter do not.

By suppressing ovulation and thinning the uterine lining, the Pill can reduce risk of ovarian and endometrial cancers.

Glands in our bodies, called endocrine glands, produce hormones; additionally, testes and ovaries — which are parts of the human reproductive system — manufacture hormones. Human hormones are powerful chemicals, which do all sorts of jobs, from triggering puberty to helping us extract energy from the foods we eat. So it’s not a huge stretch to wonder if exposure to the hormones present in certain birth control methods — such as the Pill, in addition to the patch, the ring, the shot, the implant, and some types of IUDs — might have unintended effects on the body. Because hormones can play a role in cancer — either in protecting against it or aiding in its development — researchers are very interested to know if the Pill might increase or decrease risk for various types of cancer.

It’s actually a bit tricky to investigate the possible associations between the Pill and various types of cancer. First of all, there are dozens of types of birth control pills, all with different versions of synthetic hormones, at different dosages, and in different proportions to one another. Furthermore, the types of oral contraceptives on the market change over time — today’s birth control pill is not your mother’s birth control pill. Studying “the Pill” as a single entity could obscure differences between brands. Secondly, most cancers tend to develop later in life, many years after someone may have taken oral contraceptives. Researchers need to be careful to control for all the variables that might increase or decrease cancer risk. Continue reading →

Bacterial vaginosis, or BV, is the most common vaginal infection among people 15 to 44 years of age. It’s caused by an overgrowth of harmful bacteria, such as Gardnerella vaginalis. A healthy vagina hosts thriving populations of Lactobacillus bacteria species, but when these “good” bacteria are crowded out by certain types of “bad” bacteria, the vaginal ecosystem can be shifted, causing BV.

There is a lot of confusion about BV. Is it a sexually transmitted disease (STD)? What are the symptoms? How can you avoid it?

All good questions. Let’s examine them one by one.

Is BV an STD?

The consensus seems to be that BV isn’t officially an STD, but even reliable sources have somewhat contradictory information. Planned Parenthood doesn’t list BV as an STD on their informational webpages. The Centers for Disease Control and Prevention (CDC) does include BV on their STD website, but also says that “BV is not considered an STD.”

On the other hand, the Office on Women’s Health says that “BV can … be caused by vaginal, oral, or anal sex” and that “you can get BV from male or female partners.” And there’s an entire chapter devoted to BV in the premier medical textbook on STDs, and its authors say that, while sexually inexperienced females can get BV, “the weight of evidence supports sexual transmission” of G. vaginalis, the bacteria species most famously implicated in BV infections.

The same webpage on which the CDC declared BV not to be an STD also says that it can be transferred between female sexual partners. Indeed, women who have sex with women have higher rates of BV. Since vaginal fluid could spread BV, partners can change condoms when a sex toy is passed from one to another, and use barriers like dental dams when engaging in cunnilingus (oral contact with the female genitalia) or rimming (oral contact with the anus).

Is Douching Safe?

Posted on by

This vintage douche ad claims that its product is “safe to delicate tissues” and “non-poisonous.”

Douching is the practice of squirting a liquid, called a douche, into the vagina. Many people believe it helps keep the vagina clean and odor-free, and some are under the impression that it helps prevent pregnancy and sexually transmitted diseases. An estimated 25 percent of American women 15 to 44 years old douche regularly. But just because douching is widespread doesn’t mean it’s safe; indeed, there are two possible mechanisms by which douching might be harmful.

First, douching might alter the pH of the vagina, changing its ecosystem. You might not think of a vagina as an “ecosystem,” but the bacteria and other microscopic organisms that live there sure do — and altering their habitat can harm the beneficial microbes that live there, opening the door for disease-causing microbes to take over the territory. Frequent douching can result in the vagina’s normal microbial population having difficulty reestablishing its population.

Douching increases risk for infections and fertility problems, and has no proven medical benefits.

Second, a douche’s upward flow might give pathogens a “free ride” into the depths of the reproductive tract, granting them access to areas that might have been difficult for them to reach otherwise. In this manner, an infection might spread from the lower reproductive tract to the upper reproductive tract. Douching might be an even bigger risk for female adolescents, whose reproductive anatomy is not fully formed, leaving them more vulnerable to pathogens.

While douching is not guaranteed to harm you, there is no evidence that it is beneficial in any way. Establishing causation between douching and the problems that are associated with it is trickier — does douching cause these problems, or do people who douche also tend to engage in other behaviors that increase risk? So far, the best evidence indicates that douching is correlated with a number of diseases and other problems, including sexually transmitted diseases (STDs), bacterial vaginosis, pelvic inflammatory disease, fertility and pregnancy complications, and more.

Over 90 Percent of What Planned Parenthood Does, Part 24: Miscarriage Management and Counseling

Posted on by

Welcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl never knew about.

holding handsMiscarriage. It’s a common occurrence — at least 10 to 15 percent of all pregnancies end this way — but one that is not often spoken about. When carrying a wanted pregnancy, its sudden loss can trigger a range of emotions. During this time, Planned Parenthood can help.

There is no “right” or “wrong” way to feel after having a miscarriage.

What Is Miscarriage?

When a pregnancy ends before it has reached the 20-week mark, a miscarriage has occurred; most miscarriages occur within the first eight weeks of pregnancy. Pregnancy loss after the 20-week mark is called stillbirth, and while it isn’t as common as miscarriage, stillbirth occurs in 1 out of 160 pregnancies.

Signs of a miscarriage include vaginal bleeding or spotting, severe abdominal pain or cramping, pain or pressure in the lower back, or a change in vaginal discharge. These symptoms aren’t specific to miscarriage — they could indicate other problems, so visit a health-care provider if you experience them during your pregnancy.

After a miscarriage, you might have pregnancy-related hormones circulating in your body for one or two months. Your period will most likely return within 4 to 6 weeks. While you may be physically ready to get pregnant again after you’ve had a normal period, you might want to consult with a health-care provider about the need for medical tests. You also might need to think about when you will be emotionally ready to try for another pregnancy. Continue reading →

STD Awareness: Do Sexually Transmitted Diseases Increase HIV Risk?

Posted on by

virion HIVYou might have heard that having an STD like syphilis, herpes, or gonorrhea can make it easier to catch HIV, the virus that causes AIDS. But have you ever wondered if this was true? Maybe it’s just a simple correlation — for example, someone who doesn’t practice safer sex would be more likely to catch HIV along with any other STD. That doesn’t mean that one causes the other, does it?

Common STDs like herpes and trichomoniasis can increase HIV risk.

But it’s not a mere correlation. If you take one person with an STD and one person without an STD and expose them both to HIV through sexual contact, the person with the STD will be at least two to five times more likely to become infected with HIV. Why is that? First, many STDs can make you more susceptible to an HIV infection. Second, the immune response triggered by many sexually transmitted infections can summon the types of immune cells that HIV targets.

Furthermore, if a person with HIV is co-infected with another STD, he or she is more likely to transmit HIV to a partner. In other words, STDs can make a person with HIV more infectious. HIV is more likely to appear in their genital secretions, making it easier to transmit HIV through sexual activity. Continue reading →
