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
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
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
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
Pre-exposure prophylaxis (also known as PrEP for short) is an increasingly popular method of HIV prevention among persons at the highest risk of infection. It involves taking one pill per day that combines two different drugs (tenofovir and emtricitabine). These are actually the same drugs used to treat people who already have HIV; however, when someone who is uninfected takes them, it makes it very difficult for HIV to establish an infection in the body should that person be exposed to the virus through sexual activity or injection drug use.
PrEP was originally approved by the FDA five years ago and it’s estimated that 136,000 people are now taking it—a figure that continues to climb significantly year over year. The vast majority of the people taking PrEP in the United States are gay and bisexual men, given that they’re the group that’s most at risk for contracting HIV here. However, as more men who have sex with men have begun taking PrEP, concerns have been raised over whether this drug might be changing their sexual behaviors.Read More
In the final budget proposal submitted by the Obama administration last year, funding for abstinence-only sex education was put on the chopping block. They proposed eliminating abstinence-only programs entirely and, although it didn't ultimately come to pass, their proposal at least showed recognition of the fact that we need a new approach to sex education in this country. Study after study has shown that promoting abstinence only just doesn’t work. In fact, if anything, it seems to be counterproductive. For example, research has found that the U.S. states with the most abstinence-only programs actually have the highest rates of teen pregnancy !Read More
Sexually transmitted diseases (STDs) are a massive public health issue in the United States. According to the Centers for Disease Control and Prevention (CDC), there are 110 million infections in the U.S. today. Furthermore, 20 million new infections are estimated to occur each year. All of these infections translate to significant healthcare costs: believe it or not, we spend an estimated $16 billion per year on STD treatment!
So what's going on with rates of STDs? Have they been increasing or decreasing over the last few years?Read More
As I watched last night’s U.S. election results come in, I was stunned and shocked. When I work up this morning, I was terrified.
These feelings are, in part, a function of my personal politics—the details of which I’ll spare you. However, I also feel these very same emotions in my capacity as a sex researcher and educator—and that’s what I’d like to talk about for a few moments. Here’s why what happened last night at all levels of government scares me.Read More
A reader submitted the following question:
“What is more probable in a random heterosexual encounter without protection: getting an STD or getting pregnant? I assume the answer will change with age (higher chances of STD for older people, higher chances of pregnancy for younger women) but I think would be interesting to know the answer for an average person.”
Thanks for this very interesting, but very complex question! There’s not a simple answer because there are a lot of unaccounted for variables here.Read More

Sex education is incredibly inconsistent throughout the United States. Some states require it, others don't. And in the states that mandate it, the information teachers are required by law to provide doesn't necessarily have to be useful, let alone correct. The fact of the matter is that American sex education is in poor shape and this is a big part of the reason why our teen pregnancy and STI rates are among the highest in the industrialized world. Check out the infographic below for a look at some frightening statistics about the current state of sex education in the U.S.Read More
My home state of Indiana has been in the news a lot lately, and most of the news coverage has portrayed it in a pretty unflattering light. This is due almost entirely to the actions of our elected officials, who appear to be out of touch with the views of everyday Hoosiers and with the scientific community on matters of sexuality and sexual health. Much has been said and written in recent weeks about passage of the Religious Freedom Restoration Act (RFRA) and the concern that its original wording was intended to license discrimination against gay, lesbian, and bisexual persons. This is a prime example of how the State government’s actions are out of step with the public, who overwhelmingly oppose discrimination against sexual minorities. Our elected officials’ disregard for science has not generated quite the same level of national attention as the RFRA law, but it is nonetheless just as concerning. In this article, I would like to take a look at the disconnect between our State government’s actions and the science, and consider its potential impact on the sexual health of Indiana residents.Read More
Anal sex is a sexual activity that is frequently reported by both men and women in America. For instance, a recent CDC survey reported that 44% of men and 36% of women in the U.S. have had anal sex at least once before in their lives. Despite the prevalence of this sexual activity, relatively little research has explored people’s motivations for trying it or what the experience is like, especially among heterosexual women. A new study in the Archives of Sexual Behavior offers a rare look into some of the reasons women report for having anal sex and their perceptions of the activity itself.Read More
In this TED talk, Elizabeth Pisani argues that, in order to prevent the spread of HIV, we need to start making policy decisions that are rational for public health instead of continuing business as usual and doing what is politically rational. Pisani uses scientific data to show how sex and drug policies that are made for political reasons can actually undermine our ability to prevent HIV and other sexually transmitted infections. Although Pisani's talk is going on five years old, I'm sharing it because her points still very much ring true. Indeed, in the last five years, politicians in the U.S. and many other parts of the world have (sadly enough) not significantly changed their positions on sex and drugs, and many of these positions remain counterproductive . Check out Pisani's full talk below for more on the importance of basing policy decisions on science instead of politics.Read More
Pre-exposure prophylaxis (or PrEP for short) has been in the news a lot lately. In case you are not familiar, PrEP refers to a new method of HIV prevention. Uninfected individuals simply take a medicine known as Truvada daily (Truvada is a combination of two different drugs, tenofovir and emtricitabine). This is actually the same medication used to treat people who are HIV-positive—and it works for them by dramatically lowering the level of the virus in the body (to be clear, this is not a cure--but it does help extend the life of an HIV-positive person significantly). However, when taken by someone who is uninfected, this drug appears to be effective at preventing the virus from ever taking hold. In fact, some studies have found that among individuals who take this drug consistently, their risk of contracting HIV is reduced by as much as 92%! A new study suggests that PrEP may have the positive side effect of protecting against other sexually transmitted infections as well.Read More
A new porn film entitled Viral Loads has earned quite a bit of attention for its graphic depictions of guys who are eager to give and receive HIV through man-on-man sex. I know some of you may be wondering how anyone could possibly find the prospect of contracting an incurable and deadly virus like HIV sexually arousing, but it turns out that there is a small subculture among men who have sex with men for whom HIV is fetishized. Before I go on, let me be perfectly clear: this is a small subculture and it is not a reflection of how the broader community of gay and bisexual men feel about HIV.Read More
