STDs 101: An Introduction to Sexually Transmitted Diseases

It’s April, which for Arizonans means a gradual increase in temperature as we head toward summer. But at Planned Parenthood Arizona it also means that it’s time to focus on sexually transmitted diseases (STDs) in observance of STD Awareness Month. While we regularly provide information about sexual health with our monthly STD Awareness series, April is the time of year to fix the spotlight on sexually transmissible microbes and the infections they cause. April is also the time of year when Planned Parenthood Arizona offers coupons for discounted STD screening, so if you’ve been putting it off, now’s the time!

Symptoms of Sexually Transmitted Diseases

First, some basic facts. STDs can be transmitted through all sexual activities — vaginal, anal, or oral sex, as well as activities involving skin-to-skin contact. STDs are most commonly caused by viruses or bacteria, though they can be caused by other agents as well, including animals! Each STD is unique, with unique symptoms, but common symptoms include:

  • rashes, open sores, blisters, or warts in the genital area
  • swelling or tenderness
  • pus, bleeding, odor, or abnormal discharge
  • itching in the genital region
  • burning sensation during urination

It’s best not to focus too closely on symptoms, though – most people with STDs actually don’t experience any symptoms whatsoever! As they say in the biz, “The most common symptom of an STD is … no symptom.” For example, most people with herpes either have no symptoms or have mild symptoms that go unnoticed. Ten percent of males and 80 percent of females with gonorrhea don’t experience symptoms, and most people with chlamydia are asymptomatic. And HIV symptoms usually take a decade to show up. If you are, or have been, sexually active, you can’t assume that the absence of symptoms means you’re in the clear. To know for sure if you have an STD, the best thing you can do is to get yourself tested. Continue reading

Abstinence-Only Education Gives Birth to Arizona’s High Teen Pregnancy Rate

Arizona has an especially high teen-pregnancy rate. Arizona also promotes abstinence-only education in its public schools.

Arizona is known for a lot of things. The Grand Canyon, our universities, beautiful sunsets.

And, oh yeah, our truly awful teen pregnancy rate.

Ranked against the other 49 states, Arizona’s teen-pregnancy rate has been in the top 5 for years. And while you probably won’t see that fact emblazoned on a license plate anytime soon, teen pregnancy still has a significant impact on Arizona residents.


Abstinence-only education teaches that the only way to prevent pregnancy and STIs is to abstain from sex, which is not very helpful to the 70 percent of teenagers who have had intercourse by age 19.


As of 2009, Arizona had the fifth highest teen birth rate in the United States. This trend is on the rise — as of 2006 the rate had increased by 6.5 percent. In 2009, 12,537 teenagers became pregnant. Of those pregnancies, 10,952 resulted in live births. While the majority of those women were either 18 or 19, that’s still about 3,500 girls under the age of 17 giving birth, a number that varies every year but generally stays in the 4000s.

STD Awareness: “Can I Get an STD from Oral Sex?”

As tools to reduce risk for STD transmission, dental dams are not to be ignored.

Many consider oral sex to be a safer form of sexual activity compared to vaginal or anal intercourse. For this reason, they might put less emphasis on the use of latex barriers, such as dental dams and condoms, during oral sex. Unfortunately, this idea is misguided and can lead to the transmission of preventable infections.

It is generally true that oral sex presents less of a risk for contracting sexually transmitted diseases (STDs) — but this risk is not trivial, especially when people are under the impression that they don’t need to use barrier methods during oral sex. Most sexually transmitted diseases can be passed along by oral sex, including chlamydia, gonorrhea, syphilis, hepatitis B, herpes (which can be transmitted back and forth from the mouth, as cold sores, to the genital region, as genital herpes), human papillomavirus (HPV), and HIV. Even pubic lice can be transferred from the genital region to eyelashes and eyebrows! Additionally, intestinal parasites are more likely to be transmitted via oral sex than through vaginal sex. A microscopic amount of fecal matter containing parasites can be infectious, and can be unknowingly ingested when present on genitals.


Seventy percent of adolescents who reported engaging in oral sex had never used a barrier to protect themselves from STDs during oral sex.


Some bacterial STDs, such as gonorrhea and syphilis, can do permanent damage if not treated in time. Furthermore, gonorrhea of the throat is much more difficult to treat than gonorrhea in the genital or rectal areas. And some viral STDs can’t be cured (such as herpes and HIV), while others can cause chronic infections that have been linked to cancer (such as hepatitis, which is associated with liver cancer, and HPV, which is associated with throat cancer as well as cervical cancer and anal cancer).
