7 common infections that can be caused by sex

  • INSIDER consulted experts on the most common infections to look out for

Practicing safe sex is an important part of protecting your reproductive health and warding against unpleasant infections. Though most people are aware that you can contract STIs such as chlamydia and gonorrhea through sex, there are actually several more infections that can be tied to sexual activity.

INSIDER consulted with Dr. Damian Jacob Sendler, chief of the division of clinical research at Felnett Health Research Foundation, about a few of the most common infections that can be caused by sex.

Chlamydia is a very common infection, but it can have serious consequences.

Chlamydia is the most commonly diagnosed STI in the United States. The Centers for Disease Control and Prevention (CDC) estimates that there about 1.7 million new cases each year.

Symptoms of chlamydia include abnormal vaginal discharge and the sensation of itching or burning. However, people don’t experience any symptoms at all. „The most concerning problem [with chlamydia] is getting pelvic inflammatory disease (PID),“ Dr. Sendler told INSIDER. „Untreated PID leads to scarring of the tissues inside the uterus and Fallopian tubes, preventing women from becoming pregnant. It is the number one cause of infertility among women.“

Pregnant women can also pass chlamydia to their infants during delivery, which can lead to blindness and pneumonia in the child.

HPV is also very common and can lead to cancer.

The human papilloma virus, or HPV, is a sexually transmitted virus that can lead to cancer in all sexes.

According to the CDC, there are over 40 distinct types of HPV. HPV types 16 and 18 are responsible for about 66% of cervical cancers in the US, while HPV types 6 and 11 account for approximately 90% of genital warts. Though many people infected with HPV don’t exhibit any symptoms, the virus often leads to crusty, elevated warts on the skin of the penis, vagina, or anus.

Dr. Sendler revealed that the majority of sexually active people are actually carriers of the virus. „Nearly 80% of sexually active people have acquired HPV at some point in their life. Thanks to efficient immunological protection, most of us don’t experience any negative symptoms associated with the infection,“ Dr. Sendler explained.  

This is why it’s important that people with a cervix get an annual Pap smear to detect abnormal cells, which can indicate an elevated risk of developing cervical cancer in the future. „Thankfully, it takes anywhere between 10-20 years to develop full-blown cancer, so annual Pap smears are sufficient to detect abnormal changes before the patient develops cancer,“ Dr. Sendler told INSIDER.

Even if you don’t have a cervix, you may want to consider getting an HPV vaccine. Dr. Sendler told INSIDER that it is an effective way of preventing a range of different cancers, including penile and anal cancer.

Gonorrhoea can cause burning discharge and infertility.

Gonorrhea is the second most common STI in the US. It’s also a major cause of PID, which can lead to infertility and chronic pelvic pain. The most common symptom is mucosal inflammation of the cervix or the penis, which leads to clear discharge, Dr. Sendler explained to INSIDER. Most people also report burning during sex or burning discharge coming out of the tip of the penis.

„Gonorrhea often co-occurs with chlamydia. Therefore, it is very important to receive treatment for both of these STDs. The treatment should also include your sexual partner, as they might be infected as well,“ advised Dr. Sendler. „Needless to say, if one of the partners is untreated and continues to be infected, you are more likely to experience re-infection.“

The CDC reported that in 2017, 50% of reported gonorrhea cases in the US occurred in just 70 counties. Rates of infection are highest among people 15 to 29 years of age.
