STD Awareness: “Can STDs Lead to Infertility?”

Posted on April 22, 2013 by Anna

Being diagnosed with a sexually transmitted disease (STD) can be upsetting. Some take it as evidence that they’ve been cheated on; others wonder if they can ever have sex again. Some people who have long dreamed of having children might worry about what impact, if any, their STD could have on future fertility. The bad news is that certain STDs can make it difficult or impossible to have children. But the good news is that STDs are avoidable — and regular STD screening can ensure that infections are caught and treated before they have time to do damage.

It’s common for STDs not to have symptoms, and infections can cause tissue damage — unbeknownst to you!

Fertility can be impacted in several ways. The ability to become pregnant and bear children can be affected by a condition called pelvic inflammatory disease, which is usually caused by untreated gonorrhea or chlamydia infections. If you have a cervix, an infection with a high-risk strain of HPV can require invasive treatment, which in some cases might affect the ability to carry a pregnancy. If you have a penis, an untreated STD might lead to epididymitis, which in extreme cases can cause infertility.

Pelvic Inflammatory Disease (PID)

Many sexually transmitted infections are localized; for example, the bacteria that cause gonorrhea usually just hang out on the cervix. But untreated infections can spread on their own, and bacteria can also hitch a ride on sperm or the upward flow of a douche, which can take them into the cervix, through the uterus, down the fallopian tubes, and to the ovaries. At any of these locations, microbes can stake claim on your reproductive real estate, establishing colonies deep in your reproductive system. As these colonies grow, the bacterial infections become more widespread, and can cause scarring and other tissue damage. To keep these interlopers from getting through the front door, sexually active people can use barrier methods, such as latex condoms — especially with spermicides. There’s no need to host an open house for sexually transmitted bacteria in your uterus. Continue reading →

6 Myths About HPV

Posted on January 2, 2013 by Anna

When I was a high school student in the 1990s, human papillomavirus (HPV) didn’t get a lot of screen time in our sex education classes. They slapped a few scary pictures of genital warts on the overhead projector and called it a day, neither mentioning that other strains of HPV could cause cancer, nor elucidating the connection between the virus and Pap testing.

Since the introduction of the HPV vaccine, awareness of the virus has skyrocketed — but with that increased awareness has come a flurry of myths and misinformation.

1 Myth: Condoms are useless in protecting against HPV.
Fact: The consistent use of condoms decreases the risk for HPV transmission.

Many people claim that condoms are worthless protection against HPV, reasoning that because the virus lurks in skin cells and condoms don’t cover the entire genital region, HPV transmission can still result from skin-to-skin contact. There is a kernel of truth here, but it is an exaggeration that condoms are useless. Although latex condoms don’t necessarily cover the entire affected area, using them consistently and correctly lowers the risk of contracting HPV. While latex condoms are even more effective in protecting against fluid-borne sexually transmitted diseases (STDs) such as HIV and chlamydia, they can still reduce the spread of HPV.

One study found that over an eight-month period, females whose male partners used condoms each and every time were 70 percent less likely to acquire HPV than were females whose partners used condoms only 5 percent of the time. This is hardly a case against condoms!

Other studies have shown that condom use can promote the regression of both cervical-cell abnormalities and penile lesions, as well as increase the speed at which HPV is cleared by the immune system. Put in plainer English, even if you’re already infected with a cancer-causing strain of HPV, using condoms can decrease your chances of developing cervical or penile cancer.

2 Myth: If you abstain from sex until marriage, you don’t have to worry about STDs, including HPV.
Fact: Even if you only have had one sexual partner, you can still acquire an STD. Continue reading →

“I Didn’t Want to Believe It”: Lessons from Tuskegee 40 Years Later

Posted on November 15, 2012 by Matt

Located among longleaf pine and hardwood trees, low ridges, and broad floodplains, Tuskegee, Alabama, is a small town that’s been a big part of American history. Despite a modest population of less than 10,000 people, Tuskegee has been able to boast many notable residents who have made names for themselves in everything from sports to the arts. Among them have been the Tuskegee Airmen, the first African American Air Force unit, which served during World War II, and Rosa Parks, the icon of the civil rights movement, who sparked the Montgomery bus boycott in 1955.

The Tuskegee syphilis experiment, conducted from 1932 to 1972, examined the natural progression of untreated syphilis in poor, rural black men — without their informed consent.

Tuskegee, though, is also remembered for one of the worst chapters in the history of medical research. Forty years ago, in 1972, newspapers revealed the story of a syphilis study that was callous in its deception of research participants, and damaging, even today, in the distrust it sowed among black Americans. The study had started another 40 years prior, in 1932, when the United States Public Health Service (USPHS) needed to rescue a financially troubled syphilis intervention in Macon County, Alabama. The intervention was first established in partnership with a Chicago-based philanthropic organization, but its future was uncertain when the organization’s funds dried up during the Great Depression.

Syphilis, the sexually transmitted disease caused by the bacterium Treponema pallidum, was the subject of conflicting scientific hypotheses at the time, including the hypothesis that the disease behaved differently in blacks and whites. Interested in testing those hypotheses and faced with disappearing funds for treatment, the USPHS turned its project into a study of untreated syphilis. Also influencing the decision was the fact that the USPHS was discouraged by the low cure rate of the treatments at the time, mercury and bismuth. But by the mid-1940s, penicillin was in use as a proven treatment for syphilis. In spite of that medical advance, the USPHS withheld treatment from a total of 399 infected patients by the time the study ended in 1972. Continue reading →

STD Awareness: Sexually Transmitted Diseases and Pregnancy

Posted on August 21, 2012 by Anna

Every month since January 2011, we’ve been sharing installments of our STD Awareness series, and each month, we’ve encouraged you to protect yourself from sexually transmitted diseases (STDs) by using dental dams and condoms. But what if you’re trying to get pregnant? In that case, you’re probably not using condoms! However, it is very important that partners know their STD status — being screened and treated for STDs prior to pregnancy is a good idea for your health, and can protect your future baby.

If you and a partner are trying to get pregnant, you might consider being screened for STDs together.

When present during pregnancy, certain STDs can have negative health effects for you or your future baby (including preterm labor, stillbirth, low birth weight, pneumonia, certain infections, blindness, and liver disease), especially if they are not cured or treated in time. Receiving prenatal care can help prevent these problems, so it is important to be screened and treated for STDs prior to or early in your pregnancy.

During pregnancy, the immune system undergoes changes, which are probably necessary to ensure that the body doesn’t reject the fetus — normally, the immune system recognizes non-self cells as potential pathogens and attacks. These immune system changes might make a pregnant person more susceptible to disease. Latent viral infections, like genital warts or herpes, might come out of dormancy. Additionally, anatomical changes lead to a larger exposed area of the cervix, which is potentially more vulnerable to initial infections. Continue reading →

Over 90 Percent of What Planned Parenthood Does, Part 6: Vaccinations

Posted on August 14, 2012 by Anna

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 doesn’t know about.

You know what they say: An ounce of prevention is worth a pound of cure. Public health experts agree that vaccines are one of the most important advancements in medicine, and are incredibly safe and effective in preventing infectious disease. Many infectious diseases that used to lay waste to their victims are now unknown to many of us in the developed world — polio, whooping cough, measles, and rabies struck fear in the hearts of our forebears, but most young people today barely know what they are (although low rates of vaccination can still lead to outbreaks, such as 2008’s measles outbreak in Tucson). Smallpox, once a terrifying scourge, has been wiped off the planet thanks to vaccination campaigns.

We offer vaccinations against hepatitis A and B, as well as HPV.

Vaccines work by introducing antigens to your immune system. An antigen is a substance, such as a protein on the surface of a virus, that the immune system can recognize as dangerous. It is then able to attack the pathogen and, often, create a “memory” of that pathogen so it can attack it in the event of reinfection. The antigens in vaccines are very safe, and can be derived from many sources, such as inactivated (dead) or attenuated (weakened) pathogens, or fragments of pathogens. Some vaccines, such as those protecting against human papillomavirus and hepatitis B, are made with laboratory-synthesized fragments of the surface proteins of viruses, which are sufficient to produce immune response despite being completely noninfectious.

Planned Parenthood Arizona offers vaccinations against hepatitis A, hepatitis B, and human papillomavirus (HPV). All three of these viruses can be transmitted sexually, and hepatitis B and HPV can cause cancer if the infections become chronic. The hepatitis vaccines have led to all-time lows in rates of hepatitis A and hepatitis B; the HPV vaccine is still new, but emerging evidence suggests a possible decrease in HPV rates as herd immunity grows. Vaccination doesn’t just benefit you and your partner(s) — it benefits society as a whole. Continue reading →

World Hepatitis Day: The History of the Hepatitis B Vaccine

In the early 1970s, Ted Slavin, a hemophiliac, learned his blood was special. Over a lifetime of transfusions, he had slowly amassed a huge collection of antibodies, which are proteins produced by the immune system that attach to invaders, such as viruses and bacteria. When he started receiving transfusions in the 1950s, blood wasn’t screened for diseases, which meant that he’d been repeatedly exposed to some pathogens. His immune system manufactured large amounts of protective antibodies to battle these constant invaders, one of which was hepatitis B virus (HBV) — resulting in blood with extremely high concentrations of hepatitis B antibodies.

After sunshine and smoking, hepatitis B is the most common cause of cancer.

His physician relayed this discovery to Slavin — most doctors wouldn’t have bothered, and in fact might have surreptitiously sold his blood to researchers. Back then, scientists were at work on a hepatitis B vaccine, and hepatitis B antibodies were a hot commodity. Likewise, Slavin needed money — his medical condition precluded regular work, and treatments were costly. He contracted with labs and pharmaceutical companies to sell his antibodies directly, for as much as $10 per milliliter and up to 500 milliliters per order.

When someone has a chronic HBV infection, the virus has “hijacked” some of his or her cells, “tricking” them into manufacturing copies of the virus. A virus consists of an outer protein shell housing genetic information — the blueprint that cells follow when they produce virus copies. When hepatitis B viruses are manufactured in cells, an excess of surface proteins is produced — these waste products litter the bloodstream, and testing for their presence allows people to be diagnosed with HBV infections. These surface proteins are called antigens — and as luck (or evolution) would have it, the antibodies our immune systems produce can attach to viral antigens, helping us to keep pathogens at bay.

STD Awareness: HPV in Males

Posted on June 13, 2012 by Anna

Human papillomavirus, or HPV, can affect both males and females.

Human papillomavirus, or HPV, affects people of all genders.

Whether it’s worries over Gardasil making girls go wild, or it’s somber discussion about cervical cancer, discourse about human papillomavirus (HPV) centers around its impact on females. But who are most of these females getting HPV from? For the most part, they’re getting it from male partners. And despite the fact that cervical cancer is the most common cancer associated with HPV, it is not the only one. A high-risk strain of HPV can lead to cancers of the penis, anus, mouth, and throat; additionally, there are strains of HPV that cause genital warts, which affect males and females equally. So why don’t males figure very prominently in discussions of HPV and the preventive vaccine, Gardasil?

Mouth, throat, penile, and anal cancers can all be caused by HPV.

Some people think that if they remain abstinent until marriage, they will be able to avoid sexually transmitted diseases (STDs) — but not very many people can say with certainty that their spouses have never had any other sexual partners. Eva Perón, the second wife of Argentine president Juan Perón and a leader in her own right, was made famous here by the musical Evita. According to physician and writer Shobha S. Krishnan, she died in 1952 of cervical cancer — the same fate that befell her husband’s first wife. Many believe that Juan Perón was the source of both women’s ultimately fatal HPV infections.

While one’s own sexual behavior can increase risk for acquiring an STD, it is not the only factor — the sexual history of one’s partner also plays an important role. HPV is especially tricky because there is currently no FDA-approved test for HPV in males — despite the fact that more than half of sexually active males are estimated to have been infected with HPV at some point in their lives. And, because it is so often asymptomatic, a male can carry this virus without knowing it, unwittingly infecting his partners. Continue reading →
