The human papillomavirus (HPV) is the most common sexually transmitted infection and it’s responsible for a number of negative health effects. In addition to genital warts, it has the potential to cause a number of cancers, including those of the cervix, anus, and throat. A vaccine that can prevent HPV (and, therefore, its associated health problems) has been around for nearly a decade; however, it continues to be widely underutilized in the United States.Read More
We are getting closer and closer to eradicating HIV, a sexually transmitted infection that has contributed to the deaths of at least 32 million people worldwide since the early 1980s. However, something that’s likely to surprise a lot of people is that scientists believe we may be able to eradicate HIV before we ever even find a cure for it. Yep, you read that right.Read More
The human papilloma virus (HPV) is one of the most common sexually transmitted infections. More than one hundred strains of HPV exist and, while most of them don’t cause problems, some do—and those problems are potentially quite serious. For example, HPV has been linked to cancers of the cervix, throat, and anus.
So what exactly happens inside the body when someone contracts one of the dangerous strains of HPV? How can you learn whether or not you’ve been infected? And what can you do to reduce the risk of contracting an HPV infection?Read More
Sex is seasonal.
Our patterns of sexual activity ebb and flow throughout the year, and right now we’re entering peak territory because it’s officially summer. Research from a variety of sources suggests that early summer is one of the busiest times for, well, getting busy. Here’s some of the evidence:
Gonorrhea is a relatively common sexually transmitted infection (STI) that can be passed along through oral, vaginal, and anal sex. It was once thought that these were the only sexual activities that posed a significant risk for this particular STI; however, a recent study suggests that gonorrhea can potentially be transmitted through kissing as well, regardless of whether any genital contact occurs.Read More
Some physicians argue that male circumcision should be a routine procedure because it can help fight the spread of sexually transmitted infections (STIs). Not only does circumcision reduce men’s odds of contracting STIs, they say, but it also lowers women’s risk of contracting STIs and developing cervical cancer.
But is male circumcision really that effective when it comes to protecting sexual health?Read More
In the last few years, Google Trends has become a favored research tools of sex scientists. Because not everyone is willing to participate in sex studies for various reasons, Google searches offer a handy means of looking at what a broader swath of the population thinks about sex. The appeal doesn’t stop there, though.
We also know that people don’t always answer survey questions honestly (even when they’re guaranteed anonymity) due to fear, shame, and embarrassment. For instance, some people may not honestly report their turn-ons because they’re embarrassed, while others might lie about how many people they’ve had sex with in order to look good to the researcher (some might overreport, while others might underreport). When people go to Google, however, they have a powerful incentive to tell the truth: if they don’t, they won’t find what they’re looking for.
Google searches are therefore thought to be very revealing because they can give us a glimpse into the things that people might not otherwise be willing to share. Several research papers have been published recently that explore the contents of Americans’ Google search histories. Here are five of the most fascinating things we’ve learned so far from this unique research tool.Read More
There's a scene in the movie Mean Girls in which high school health teacher Coach Carr gives his students a lesson in sex education. It pretty much consists of him saying: "Don't have sex, because you will get pregnant...and die!"
As much as I wish I could say Coach Carr's class bears no resemblance to how we teach kids about sex in the real world, the sad fact of the matter is that the primary message many U.S. educators are sending out about sex is to be afraid. Be very afraid. Unfortunately, it turns out that this approach to sex education is problematic on multiple levels.Read More
Condoms are one of the best tools we have available for reducing the spread of sexually transmitted infections (STIs) and preventing unintended pregnancies. Unfortunately, however, they don’t provide quite as much protection as they could. This is because people make a lot of mistakes when it comes to wearing and using condoms. These mistakes include using sharp objects to open condom packages, failing to check the expiration date, and taking the condom off before sex is over.
Why are these and other condom use errors so common? There are multiple reasons, not the least of which is a lack of knowledge about proper condom use, owing in large part to poor sex education. However, a study published in the journal Sexually Transmitted Infections suggests at least one other important contributor: rushed condom application.Read More
A few years ago, I decided to get the HPV vaccine. This vaccine didn’t hit the market until I was well into adulthood, so I didn’t have a chance to be vaccinated in my youth like most kids today (about 6 in 10 US parents are currently choosing to have their kids vaccinated against HPV). Unfortunately, I found that it was a ridiculously difficult and expensive process.
Because the recommended age for the vaccine is only up to 26—and I was older than that—my insurance company wouldn’t cover it and many providers weren’t willing to give it to me, even though I said I would pay out of pocket (long story short: I eventually got it, and you can read all about the experience here). Fortunately, things look like they’re about to get easier (and cheaper) for the over-26 crowd.Read More
Many sex education programs in the United States fail to meet the needs of sexual and gender minority students. This is especially true for programs that have an abstinence-only focus. Research has found that LGBTQIA students who take such courses report that they not only reinforce negative stereotypes, but they are also seriously lacking when it comes to providing useful and relevant information and resources .
We need comprehensive and inclusive sex education—and there are a lot of wonderful people in my field who are working to change the way that we approach sex ed around the world; unfortunately, however, there’s a lot of political resistance and progress is slow. The good news, though, is that some sex educators have begun to put together valuable educational resources for LGBTQIA students that are readily available to anyone with an internet connection.Read More
In the United States today, 37 states mandate that information on abstinence be provided in sex education courses. As you might imagine, it’s not uncommon for students to be asked to take “purity” or virginity pledges as part of the sex ed. curriculum in these states.
Students are encouraged to take these pledges in order to reduce the spread of sexually transmitted infections, but also to prevent unwanted pregnancies. As it turns out, however, abstinence pledges don’t necessarily accomplish either of these goals. In fact, a recent study published in the Journal of Marriage and Family suggests that they might do just the opposite!Read More
Our sexual behavior patterns change with the seasons--and with the shift from spring to summer just around the corner, research suggests that a change in sexual behavior is likely to follow. Specifically, there seems to be a reliable peak in sexual activity during the summer months.Read More
How many people have had oral sex? Do men and women have similar feelings about this activity? Does oral sex "count" as sex? In this post, we'll take a look at the answers to these and other questions about oral sex.
1.) Most adults in the United States have engaged in oral sex before. A recent, nationally representative survey found that 86-87% of men and women say they have done it at least once.Read More
Today is World AIDS Day, a global public health campaign that began 29 years ago in order to increase HIV/AIDS awareness and education. In support of this campaign, I'm sharing a video created by our friends over at ASAP Science that offers some useful and important information on the subject. Specifically, this video details how HIV affects the body, it discusses why a cure has been so elusive, and it offers a glimpse into the future of HIV treatment. Check it out, and be sure to do your part in contributing to HIV awareness and education by sharing it.Read More
New research finds that the antibiotic doxycycline reduces the odds of contracting some bacterial sexually transmitted infections (STIs) if taken within 72 hours of condomless sex.
The findings, presented earlier this year at the Conference on Retroviruses and Opportunistic Infections, came from a study of 232 HIV-negative men who have sex with men (MSM). Half of the men were given a prescription for the drug and instructed to take two pills (100 mg) within three days any time they had sex without condoms. The remaining men did not receive the antibiotic regimen; however, everyone was given condoms and counseling about safer sex. All participants were tested regularly for STIs for several months afterward.Read More
In the modern world, we have a tendency to blame almost all of our problems on technology--and this is especially true when it comes to sexual problems. For example, I’ve written a lot about how we like to blame everything on pornography, from sexual violence to risky sex to erectile dysfunction, among other things. In all of these cases, porn serves as a convenient target, but it's not necessarily the right one.
Today, I want to focus on a different form of technology that's been getting a lot of blame for sexual problems: online dating apps. They’ve been in the news a lot lately, with many pointing to them as the culprit for rising rates of STDs. Headlines like this make it clear what I mean: “Tinder and Grindr Dating Apps are Causing Cases of Syphilis, Gonorrhea, and HIV to soar.”Read More
Sexually transmitted diseases (STDs) are a major public health concern in the United States. According to the Centers for Disease Control and Prevention (CDC), there are estimated to be 110 million infections in the U.S. today, with 20 million new infections occurring each year. So what's been happening with STD rates over the last few years? Have they been rising or falling? And is the pattern similar or different across various infections? For a look at the data, check out the infographic below, which includes selected figures complied from the CDC's website.Read More

This past summer, I taught a study abroad course on sex and culture in the Netherlands. We covered a lot of ground in this class, including an in-depth look at what a legalized prostitution system looks like and the implications of it for the mental and physical health of Dutch sex workers. In addition, we spent a lot of time talking about differences in sex education in the Netherlands compared to the United States. It turns out that these countries have radically different approaches to sex ed, and there’s a lot we can learn from the Dutch.Read More
