The earliest known illustration of a man using a condom during sexual intercourse is painted on the wall of a cave in France. It is 12,000–15,000 years old (Parisot, 1987). We know that condoms have been used to protect against sexually transmitted infection since the 16th century and to prevent unwanted pregnancy since the 18th century (Himes, 1963). Since the 19th century, American moralists — who have misunderstood or denied its public health benefits — have attacked condom use (Brodie, 1994).
As a result, those who promoted an abstinence- until-marriage agenda stymied public health efforts toward increased condom use in the U.S for most of the 20th century. During World War I, for example, U.S. allies, including New Zealand, gave their troops condoms to prevent sexually transmitted infection. But social hygienists in the U.S. forced the American Expeditionary Forces to adopt a chastity campaign — they were opposed to any prophylactic prevention of sexually transmitted infection. Consequently, in 1919 alone, U.S. troops reported a yearly admissions rate of 766.55 per 1,000 for sexually transmitted infection (Brandt, 1985).
In the last several years, certain anti-choice radicals have even distorted scientific fact in order to discourage condom use. Three myths propagated in this anti-condom misinformation campaign are particularly dangerous. The first myth purports that talking about condoms or giving people condoms will make them sexually promiscuous (Hartigan, 1997). The second claims that condoms cause AIDS because HIV allegedly passes through microscopic pores in the latex (A.L.L.). The third blames condoms for cervical cancer (Lerner, 1999; Cantu & Farish, 1999). These myths are now so widespread that they are recited in Congress and have been incorporated into the sexuality education programs of more than a third of U.S. schools (Darroch et al., 2000; Lerner, 1999; Landry et al., 1999). But none of these myths are true.
As this fact sheet will make clear, the effectiveness of condoms against unintended pregnancy and sexually transmitted infection has long been established (see below). Further, information about and access to condoms clearly do not increase sexual activity among adolescents (Kirby, 1997; Schuster et al., 1998). One World Health Organization review of 19 studies found no evidence that sexuality education programs lead to earlier or increased sexual activity among teens (NCHSTP, 1996).
But easy access to condoms does encourage condom use among teens that are already sexually active (Blake et al., 2003). A study of more than 4,000 sexually active adolescents showed that condom use at sexual debut is associated with a twofold increased likelihood of subsequent condom use (Shafii et al., 2004). In fact, adolescents who use condoms the first time they have vaginal intercourse do not have more partners, are more likely to protect themselves and their partners, and are less likely to get an STI than adolescents who don’t use condoms the first time they have vaginal intercourse (Shafii et al., 2007). And teens need protection — more than 60 percent of young women and men in the United States have had sexual intercourse by the age of 19 (Hebernick et al., 2010).
The truth about condoms is that they offer the best protection for the sexually active (Stone et al., 1999; CDC, 1998).
Nevertheless, scientifically based information about condoms **that was available on government health websites has been either taken down or replaced with politically driven, censored pages that emphasize abstinence and have an exaggerated focus on the potential risks of condom use. **For example, the Centers for Disease Control and Prevention (CDC) website expunged information showing that education about condoms does not result in increased or earlier sexual activity (Clymer, 2002).
The U.S. Public Health Service has included increased condom use as an objective in its Healthy People 2000 and 2020 campaigns to promote health and prevent disease. The federal government plans to “increase the proportion of sexually active persons 15 to 19 years who use condoms to both effectively prevent pregnancy and provide barrier protection against disease at first intercourse and at last intercourse (DHHS, 2010).” In fact, condom use among adolescent women and men has increased from 1991 to 2010, during which time 58.1 percent of women and 79.1 percent of men reported using condoms at last intercourse. And black and Latino women and men report more condom use than their white counterparts (Reece et al., 2010).
In June 2000, a number of federal agencies including the CDC, National Institutes of Health (NIH), U.S. Food and Drug Administration (FDA), and the U.S. Agency for International Development (USAID) sponsored a workshop to look at the scientific evidence of the effectiveness of latex condom use to prevent the spread of STIs during vaginal intercourse. The report that resulted from this meeting confirmed that condoms are the best method for sexually active people to prevent STIs. It states that research shows condoms to be effective against pregnancy, HIV, and gonorrhea, and that while there is research that finds condoms to be effective against other STIs, more research needs to be conducted to more firmly establish condom efficacy (NIAID et al., 2001). In fact, the CDC, which is the agency responsible for prevention messages, continues to promote condom use for general STI protection (CDC, 2004).
Condoms are effective because they block contact with body fluids that cause pregnancy and sexually transmitted infection. Most reports of condom failure are the result of inconsistent or incorrect use, not breakage (Macaluso et al., 1999). A recent study of college students found that condom use errors were very common — 40 percent of the young men surveyed reported that, within the previous three months, they had not left space for ejaculate at the tip of a condom, and 15 percent had taken a condom off before completing intercourse (Crosby et al., 2002). In the U.S., the actual breakage rate is a low two per 100 condoms (CDC, 1998).
High failure rates in some studies occur because many people over-report contraceptive use to shift the responsibility for an unintended pregnancy to a “faulty” contraceptive. Such over-reporting artificially inflates failure rates (Trussell, 1998). Condom failure rates are also inflated because some young people have been shown to inaccurately report condom uses, use condoms incorrectly, and respond to survey questions with what they perceive to be socially desirable answers (Rose et al., 2009). In fact, most people who use condoms do not experience breakage or slippage. Most condom failures occur among a minority of users because they are less experienced and/or less careful about using condoms than more successful users (Steiner et al., 1993, Steiner et al., 1994).
Condoms are an effective, inexpensive form of birth control. Of 100 women whose partners use condoms inconsistently or imperfectly, 18 will become pregnant in the first year of use. Only two will become pregnant if condoms are used perfectly (Trussell, 2011). Unlike many other forms of birth control, condoms also protect against sexually transmitted infection. Additional advantages of condoms as birth control include low cost, easy access, simple disposal, minimal side effects, and longer-lasting sex play. Using condoms can also enhance sexual pleasure by reducing anxieties about the risk of infection and pregnancy (Warner & Hatcher, 1998).
Condoms offer effective protection against most serious sexually transmitted infections by preventing the exchange of body fluids (Cates & Stone, 1992; CDC, 1998; Stone et al., 1999). Such fluids — semen, genital discharge, or infectious secretions — are the primary routes of transmission (Stone et al., 1999). While latex condoms may not completely prevent skin-to-skin contact, they offer the best protection possible because the glans and shaft of the penis are the major portals of exit and entry of sexually transmitted infections (Stone et al., 1999). (In order to be effective, condoms must be used consistently and correctly, put on prior to genital contact, and used throughout contact [Cates & Stone, 1992; CDC, 1998]).
Condoms offer good protection against sexually transmitted bacterial infection — chlamydia, gonorrhea, trichomoniasis, and syphilis (Stone et al., 1999; Judson et al., 1989). During the 1980s, genital chlamydia became the most prevalent bacterial STI in the U.S., and by 1996 there were an estimated three million new cases — this made chlamydia the most frequently reported infectious disease in the country (KFF, 1998). A 2006 review of the literature on condom use to prevent transmission of chlamydia and gonorrhea found that most studies associated condom use with demonstrable risk reduction (Warner et al., 2006). Increased condom use will help reduce the incidence of all these infections (Stone et al., 1999; Cates & Stone, 1992).
Condoms are effective against viral infections such as HIV, hepatitis B, cytomegalovirus, and herpes simplex virus 2, which are transmitted by semen, urethral fluids, and genital sores ( CDC, 2004; Judson et al., 1989; Cates & Stone, 1992)
Herpes simplex virus (HSV) type 2 causes genital herpes. Studies have shown that opposite sex couples who used condoms during one out of four acts of intercourse reduced the risk of infection with HSV 2 for the woman — but not the man — by 92 percent. Infection was even rarer among women and men who used condoms during every act of intercourse (Holmes et al., 2004)
The Centers for Disease Control and Prevention has long recommend condom usage as a way to reduce the risk of herpes infections (CDC, 1998). In fact, using condoms for every act of intercourse significantly reduces the risk of infection (Wald, 2005).
Given the serious consequences of HIV infection, much of the research about condom efficacy has focused on HIV transmission. The condom is recognized as a highly effective barrier against HIV infection (CDC, 2004).
Condom-use opponents, however, have manipulated the findings of flawed laboratory tests to create public doubt about the condom’s effectiveness against HIV. For example, one study erroneously concluded that latex condoms leak HIV virus even though it used particles that were 100 million times smaller than the HIV particles found in semen (Stone et al., 1999). In fact, the risk of HIV transmission with a condom is reduced — as much as 10,000-fold (Carey et al., 1992; Cavalieri d’Oro et al., 1994; Weller, 1993).
In a study of couples in which one partner was HIV positive, only one case of infection (two percent) occurred among those who remained sexually active and used condoms consistently and correctly. In contrast, the incidence of HIV infection was 14 percent with inconsistent use (Deschamps et al., 1996). A similar study that followed couples for an average of 20 months found there were no new cases of infection among couples who used condoms consistently (de Vincenzi, 1994). Another study found that among a group of couples who used condoms consistently, two percent of the uninfected partners contracted HIV over the course of the two-year study. This contrasts with 12 percent of partners who became infected in couples that reported inconsistent or no condom use (Saracco et al., 1993). A meta-analysis of 25 studies on HIV transmission and condoms found an average efficacy rate of 87 percent against HIV infection. However, efficacy rates can range from 60 percent to 96 percent (Davis & Weller, 1999).
Condoms provide some protection against the human papilloma viruses (HPV) that infect the general genital area (CDC, 2004). The Centers for Disease Control and Prevention recommend condom usage as a way to reduce the risk of HPV infections (CDC, 1998).
Since HPV and herpes viruses ‘shed’ beyond the covered area, however, condoms do not provide as complete protection as they do for other pathogens, but two recent Dutch studies have found that condom use has been shown to clear HPV infections in women as well as the abnormal cell growths they cause on the cervix and penis (Hogewoning et al., 2003; Bleeker et al., 2003).
Few HPV infections lead to cervical cancer. Of at least 100 types of HPV, only a handful are associated with cervical cancer (Kiviat et al., 1999; Koutsky & Kiviat, 1999). Most HPV infections are short-lived, and many women appear to develop immunity to different HPV infections. Nearly a third of women may recover from the infection within six months. Persistent infection and reinfection seems to be the higher risk factor for cervical cancer (Ho, et al., 1998).
The claims of condom use opponents regarding HPV are false and alarmist. Condom use cannot be blamed for the high prevalence of HPV or cervical cancer among women in the U.S. In fact, studies have shown an association between condom use and a reduced risk of HPV-associated diseases, including cervical cancer (CDC, 2004). As stated above, condom use has been shown to clear HPV infections and the abnormal cell growth they cause on the cervix and on the penis (Bleeker et al., 2003; Hogewoning et al., 2003). While condoms may not eliminate the risk of transmitting the HPVs that cause cancer, the CDC recommends condoms for risk reduction (CDC, 1998).
Failure to use condoms has been shown to be among the most significant risk factors for pre- cancerous conditions related to certain types of HPV (Wang & Lin, 1996).
Clearly, despite the claims of abstinence-until- marriage proponents, condoms offer the best risk reduction for sexually transmitted infections among sexually active women and men. They also provide significant protection against unintended pregnancy.
